RESEARCH Open Access Timing the market: the economic value of price extremes Haibin Xie 1 and Shouyang Wang 2* * Correspondence: [email protected] 2 Academy of Mathematics and Systems Science, Chinese Academy of Sciences, Beijing 100190, China Full list of author information is available at the end of the article Abstract By decomposing asset returns into potential maximum gain (PMG) and potential maximum loss (PML) with price extremes, this study empirically investigated the relationships between PMG and PML. We found significant asymmetry between PMG and PML. PML significantly contributed to forecasting PMG but not vice versa. We further explored the power of this asymmetry for predicting asset returns and found it could significantly improve asset return predictability in both in-sample and out-of-sample forecasting. Investors who incorporate this asymmetry into their investment decisions can get substantial utility gains. This asymmetry remains significant even when controlling for macroeconomic variables, technical indicators, market sentiment, and skewness. Moreover, this asymmetry was found to be quite general across different countries. Keywords: Price extremes, Return decomposition, Asymmetry, Return predictability Introduction It is well known that price extremes contain valuable information for estimating and forecasting the volatility of financial assets. Parkinson (1980), Beckers (1983), Garman and Klass (1980), Wiggins (1991), Rogers and Satchell (1991), Kunitomo (1992), and Yang and Zhang (2000), among others, demonstrated the superiority of using price range (defined as the difference between high and low extreme prices) as a volatility estimator as compared with standard methods. Sassan et al. (2002) show that a range-based volatility estimator is not only highly efficient but also approximately Gaussian and robust to microstructure noise. Chou (2005) proposed the conditional autoregressive range model (CARR) and found that it provided sharper volatility estimates compared to a standard GARCH model. Brandt and Jones (2006) proposed a range-based EGARCH model and found substantial forecastability of volatility. Martens and Dijk (2007) showed that realized range is a more efficient estimator of volatility than realized volatility. It remains unknown whether price extremes contribute to forecasting asset returns. Despite a great deal of research on range-based volatility, few studies, to our knowledge, have related asset returns to price extremes. In an intriguing study, George and Hwang (2004) noted that traders appear to use the 52-week high as a reference point against which they evaluate the potential impact of news. Hence, nearness to the 52-week high is positively associated with expected returns in the cross section. Further, Li and Yu (2012) suggested traders may use the historical high as another anchor Financia l Innovation © The Author(s). 2018 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

against which they evaluate information. They also showed that the 52-week high and the historical high contain information about future market returns that is not captured by traditional macroeconomic variables. George and Hwang (2004) and Li and Yu (2012) both hinted that price extremes might have additional information in explaining asset returns. This study attempted to relate asset returns to price extremes through intuitive decomposition. The next section will show that asset returns can be decomposed into potential maximum gain (PMG) and potential maximum loss (PML). The idea of decomposing asset returns into PMG and PML was motivated by both psychological and empirical findings. Mounting evidence shows that investors have different and asymmetric reactions to gains/good news and losses/bad news. Kahneman and Tversky (1979), for example, found that “the value function is normally concave for gains, commonly convex for losses, and is generally steeper for losses than for gains.”This finding indicates that traders’reactions to good news should be different from their reactions to bad news. Veronesi (1999) showed that with correct beliefs, rational investors may overreact to bad news in good times and underreact to good news in bad times when the market shifts between two unobservable states. Andersen et al. (2003) used a new dataset of exchange rate quotations, macroeconomic expectations, and macroeconomic realizations to explore real-time price discovery in a foreign exchange. They found that exchange markets react to news in an asymmetric way, and bad news has a greater impact than good news. Nguyen and Claus (2013) explored heterogenous consumers’reactions to a range of financial and economic news and found asymmetry in the responses to news, where consumers reacted to bad news but not good news. Thus, we expect that decomposing asset returns into PMG and PML could provide a new and different profile of the dynamics of asset returns. We found that both PMG and PML displayed very interesting time series properties. First, there is high persistence in both PMG and PML. It is well documented that asset returns, especially for monthly and quarterly observations, display no or low persistence. However, we found significant persistence in PMG and PML, and PML is more persistent than PMG. This finding seems to be consistent with Hong and Stein (1999), who claimed that information diffuses gradually, and with Hong, Lim, and Stein (2000), who reported that bad news travels slowly. Second, we found a significant asymmetry between PML and PMG. The Granger causality test (Granger, 1969) showed that PML caused PMG but not vice versa. Further empirical evidence showed that PML positively predicted PMG, which means that a larger potential loss implies future large potential gains. This finding suggests that investors overreact to bad news. The asymmetry found in this study is valuable for timing the market. We found that such asymmetry can be used to improve the predictability of stock returns in both in-sample and out-of-sample forecasting. Financial economists have sought to identify variables that forecast aggregate stock market returns. Welch and Goyal (2008) found that a long list of predictors from the literature was unable to deliver consistently superior out-of-sample forecasts relative to a simple forecast based on historical average. Thus, it would be of great interest to investigate the forecasting power of this asymmetry. We found a sharp increase in return predictability in both in-sample and out-of-sample forecasting once asymmetry was considered. For monthly data, the in-sample R-square ranged from 1.57% to 1.89%, and the out-of-sample R-square Xie and Wang Financial Innovation (2018) 4:30 Page 2 of 24
ranged from 0.098% to 1.46%. Similar results were obtained for quarterly data. The R-square ranged from 2.60% to 12.54% for in-sample fitting and from 0.97% to 3.87% for out-of-sample forecasting. We also investigated the economic value of this asymmetry and found that it can provide substantial utility gains. Suppose a mean-variance investor with a risk aversion of 3 invests over the market portfolio and the Treasury bill. Using asymmetry to predict the market return, the investor can obtain 0.378%–2.41% (for monthly horizon) and 2.95%–4.85% (for quarterly horizon) more annualized certainty equivalent return (CER) relative to the strategy using the historical return average as the expected market return estimate. The Sharpe ratio provides further evidence that this asymmetry generates economic value. The asymmetry between PMG and PML cannot be explained by business-cycle-related variables, technical indicators, market sentiment, and skewness. Rapach, Strauss, and Zhou (2010); Henkel, Martin, and Nardari (2011); and Dangl and Halling (2012), among others, found significant asymmetry in return forecasting. Macroeconomic variables usually show significant out-of-sample forecasting in bad times but insignificant or weaker forecasting in good times. However, we found that asymmetry cannot be attributed to business cycle. Asymmetry remains significant, even when controlling for the commonly used macroeconomic variables. Baker and Wurgler (2006) found that market sentiment has strong forecasting power for a large number of cross-sectional stock returns. Baker, Wurgler, and Yuan (2012) provided further international evidence for the cross-section forecasting power of investor sentiment. Huang et al. (2016) presented two technical indicators that significantly predict stock returns: the mean reversion indicator and the good state indicator. Huang et al. (2015) provided evidence of market sentiment predicting aggregate stock returns. However, we found that asymmetry cannot be explained by either market sentiment or technical indicators. We also investigated whether asymmetry can be explained by skewness in stock returns and found it cannot. This study is related to George and Hwang (2004) and Li and Yu (2012). However, we differ from them in at least three aspects. First, both 52-week high and historical high were constructed from closing price. In this paper, the high price extreme refers to the highest trading price over a specified time interval. Second, both 52-week high and historical high served mainly as proxies for news levels. For example, if nearness to the 52-week high is high, it is more likely that the firm experienced good news in the recent past. That is, 52-week high and historical high are used to measure the certainty of the news. In this study, the highest trading price was used as a proxy for news uncertainty. The higher the highest trading price, the more uncertainty in the price changes. Third, George and Hwang (2004) and Li and Yu (2012) focused on the effect of investors’psychology on asset pricing. This study focused instead on the time series properties of asset returns. The main contributions of this paper are summarized as follows. First, we present new evidence confirming the economic value of price extremes in forecasting asset returns. Second, we document a new asymmetry in asset returns; PML has a larger impact on PMG than PMG has on PML. This asymmetry could be used to improve return predictability. The rest of the paper is organized as follows. Section 2describes the empirical methodology. Section 3provides empirical results showing significant asymmetry between Xie and Wang Financial Innovation (2018) 4:30 Page 3 of 24
PMG and PML. Section 4shows the power of asymmetry for predicting asset returns along with its economic value in investment. Section 5presents potential explanations for asymmetry. Section 6presents global evidence for asymmetry across the main stock indices. Section 7concludes the paper. Econometric Methodology Return Decomposition Traditionally, the literature on stock returns has been exclusively based on closing price: rt¼ln Ct ðÞ−ln Ct‐1 ðÞ;ð1Þ where C t is the closing price at time t, and r t is the logarithmic return over a holding period from t-1 to t. A problem with Equation (1) is that it ignores price movements from time t-1 to t, which means there is missing information. To alleviate this problem, we propose decomposing the stock returns with the high price extreme: rt¼ln Ct ðÞ−ln Ct‐1 ðÞ ¼ln Ot ðÞ−ln Ct‐1 ðÞ½þln Ht ðÞ−ln Ot ðÞ½−ln Ht ðÞ−ln Ct ðÞ½ ¼OVRtþPMGt‐PMLt; ð2Þ where O t and H t are, respectively, the opening price and the high price over [t-1, t]. This shows that stock returns over [t-1, t] comprise three components: Overnight returns (OVR t ). OVR t =ln(O t )-ln(C t-1 ). The overnight return gauges the return due to overnight information. Potential maximum gain (PMG t ). PMG t =ln(H t )-ln(O t ). The potential maximum gain measures the possible maximum profit from the opening price to the high price extreme. Potential maximum loss (PML t ). PML t =ln(H t )-ln(C t ). The potential maximum loss measures the possible maximum loss from the high price extreme to the closing price. Equation (2) indicates not only the returns but also the equity risk. In this paper, we call Equation (2) the return decomposition. PMG and PML measure the uncertainty of price changes or the equity risk. From Equation (2), it can also be seen that PMG and PML can be used as proxies for good news and bad news. Therefore, the time series dynamics of PMG and PML describe how good news and bad news are incorporated into equity prices or the price-discovery process. The return decomposition technique was mainly based on Kahneman and Tversky (1979), George and Hwang (2004), and Li and Yu (2012). Kahneman and Tversky (1979) showed that investors behave differently when facing possible gains and losses. George and Hwang (2004) and Li and Yu (2012) found that investors use high prices as anchors. Therefore, we conjecture that high price extremes can help us to better understand the dynamics of asset returns. For data observations of low frequency, overnight returns contribute very little to variations in asset returns and thus can be neglected. In the next section, asset returns, unless specified otherwise, refer to returns with the overnight returns removed. Xie and Wang Financial Innovation (2018) 4:30 Page 4 of 24
Dynamics of Asset Returns For time series data, the most commonly used econometric tool is covariance analysis. The covariance between asset returns r t and r t-i can be presented as follows: Cov rt;rt‐i ðÞ¼Cov PMGt‐PMLt;PMGt‐i‐PMLt‐i ðÞ ¼Cov PMGt;PMGt‐i ðÞþCov PMLt;PMLt‐i ðÞ½ ‐Cov PMGt;PMLt‐i ðÞþCov PMLt;PMGt‐i ðÞ½ This equation shows that the covariance in asset returns is determined by two parts: the autocovariances in PMG t and PML t (Cov(PMG t ,PMG t-i ), Cov(PML t , PML t-i )), and the cross covariances between PMG t and PML t (Cov(PMG t ,PML t-i ), Cov(PML t ,PMG t-i )). Each part has an economic sense. The autocovariances in PMG t and PML t measure, to some extent, the persistence of good news and bad news, respectively. The larger the autocovariance, the more slowly news travels. The cross covariances between PMG t and PML t measure the interactions between PMG t-i (PML t-i ) and PML t (PMG t ). Therefore, the return decomposition shows that the time series dynamics of asset returns have very complicated and subtle intrinsic structures. We modeled the autocovariance in PMG and PML with an ARMA(l, m)-GARCH(p, q) model: St¼μþXl i¼1φiSt‐iþXm j¼1θjμt‐jþμt μt¼σtut σ2t¼ωþXp i¼1αiσ2t‐iþXq j¼1βjμ2t‐j utN0;1ðÞ;i:i:d; ð3Þ where S t = PMG t ,PML t . GARCH(p, q) was used because financial markets are notoriously well known for their heteroscedasticity. The Granger causality test (Granger, 1969) test was applied to the cross covariance. The Granger causality test is used to determine whether one time series is useful for forecasting another. A time series Xis said to Granger-cause Yif it can be shown that those Xvalues provide statistically significant information about future values of Y.The test for causality in the Granger sense is based on the following equations: Yt¼α0þXm j¼1αjYt‐jþutð4Þ Yt¼β0þXm j¼1βjYt‐jþXm i¼1γiXt‐iþvtð5Þ where u t and v t are independent, series-uncorrelated random variables with zero means and finite variances. Whether XGranger-causes Yis based on a test of the null hypothesis that γ 1 =γ 2 =…=γ n = 0. Rejection of the null hypothesis means Xcauses Yin the Granger sense. Analyzing the cross covariance between PMG t and PML t is of greater interest. First, cross covariance between PMG t and PML t can be used to describe how investors form their expectations on future gains (losses) conditional on historical losses (gains). Thus, it is related to the literature on investors’asymmetric reactions to gains and losses. Second, it is highly related to return predictability. Predicting stock returns r t conditional on the historical information set can be presented as Xie and Wang Financial Innovation (2018) 4:30 Page 5 of 24
Er tΩt−1 j ðÞ¼E PMGt−PMLt ðÞΩt−1 j ½;ð6Þ where ῼ t ={r t ,r t-1 ,….} Equation (6) shows that, unless investors predict PMG t and PML t using the same information and the same model, modeling stock returns as a unit may produce misleading results. For example, if PML Granger-causes PMG and not vice versa, then modeling stock returns as a unit is not equivalent to modeling PMG and PML: ErtΩt−1 j ðÞ¼E PMGt−PMLt ðÞΩt−1 j ½ ≠E PMGtΩdt−1 −E PMLtΩdt−1 ; where Ωdt−1¼PMGt;PMLt ðÞ;PMGt−1;PMLt‐1 ðÞ;…: fg To further quantify the interaction between PMG and PML, we performed the following regression: χt¼cþηiψt‐iþςt;ð7Þ where χ t and ψ t-i are filtered PMG t or PML t . The filtered χ t and ψ t-i were obtained by first removing the autocorrelations in PMG and PML and then standardizing the residuals. The coefficient η i directly measures the impact of unit ψ t-i on χ t . Empirical Results Data We collected the monthly index data of the Standard and Poor’s 500 (S&P 500) for the sample period January 1950 to December 2015 with 792 observations. The data set was downloaded from the finance subdirectory of the website Yahoo.com. 1 For each month, four pieces of price information—opening, closing, high, and low—are reported. Since the website does not provide quarterly index data, we constructed quarterly index data from monthly observations. The construction is presented as follows: Lqt¼MintfLm3t‐1ðÞþ1;Lm3t‐1ðÞþ2;Lm3t;Hqt¼MaxtHm3t‐1ðÞþ1;Hm3t‐1ðÞþ2;Hm3t ; Oqt¼Om3t‐1ðÞþ1;Cqt¼Cm3t;t¼1;2;3;… The labels qand mrepresent, respectively, the quarterly and monthly observations. For quarterly index data, there were 264 observations. From the collected and constructed data, the stock returns, potential maximum gains (PMG), and potential maximum losses (PML) were calculated by their definitions. Table 1presents the summary statistics on the stock returns PMG and PML. The kurtosis coefficients of the stock returns PMG and PML on either monthly or quarterly observations are larger than 3, indicating a strong deviation from the normal distribution. It is interesting to observe the difference in the values of the ACFs and the Ljung-Box Qstatistics for stock returns PMG and PML. The Qstatistics for stock returns on either monthly or quarterly observations are small and statistically insignificant at the level of 10%, indicating no significant persistence in stock returns. Meanwhile, the Qstatistics for PMG and PML are statistically significant at the level of 10%, indicating evidence of persistence in PMG and PML. The persistence in PMG and PML is consistent with Hong and Stein (1999), who suggested that information diffuses gradually. Consistent with Hong, Lim, and Stein (2000), who reported that bad news travels slowly, the Qstatistics also show more persistence in PML than in PMG. Table 2presents the correlation statistics among stock returns (r t ), PMG, PML and stock return with overnight return included (r° t ). The high correlations between r t and Xie and Wang Financial Innovation (2018) 4:30 Page 6 of 24
r° t (0.997 for monthly observations and 0.999 for quarterly observations) indicate that r ° t can be perfectly approximated by r t . Regressing r° t on r t , we found that r t can almost fully explain the variation of r° t .TheR-squares for monthly observations and quarterly observations were 99.4% and 99.8%, respectively, which means overnight returns contribute very little to variations in stock returns and thus can be omitted in our empirical analysis. The correlation between PMG and PML, instead of being uncorrelated, is reported to be significantly positive. Autocorrelations in PMG and PML The summary statistics in Table 1show that the distributions of PMG and PML are severely skewed and far from normal. In this study, we alleviated skewness by using squared root transformation on both PMG and PML. Possible heteroscedasticity was Table 1 Summary Statistics on Stock Returns, Potential Maximum Gains, Potential Maximum Losses Panel A. Monthly Index Data Panel B.

also taken into consideration. We used Equation (3) to describe the dynamics of PMG and PML. Different ARMA(l, m)-GARCH(p, q) (l=1, 2; m=1, 2; p=1, q=1) models were used, and the final models were determined by the Akaike Information Criterion (AIC). The modeling results are presented in Table 3. The results show heteroscedasticity in monthly observations but not in quarterly observations. It is interesting to note the differences in the R-square values. We found, for both quarterly and monthly observations, that PML was more predictable than PMG. The predictability of PML is almost twice that of PMG. Table 4presents the summary statistics on filtered PMG and PML. The results show that the kurtosis and J-B statistics decreased significantly after filtration compared to the results in Table 1. For PMG, the J-B statistics indicate that the null hypothesis of normal distribution cannot be rejected. The values of ACFs and Ljung-Box Qstatistics for PMG and PML are small and statistically insignificant, indicating that the autocorrelations have been well filtered. Cross Correlation Between PMG and PML Granger causality tests were employed to investigate the cross correlation between PMG and PML. Since Granger causality tests are sensitive to lags, different lags are used for robustness. We performed Granger causality tests on both unfiltered and filtered observations. Table 5reports the test results. For the unfiltered data, the null hypothesis that PML does not Granger-cause PMG is consistently rejected at the significance level of 5% for both monthly and quarterly data observations. The results for the null hypothesis that PMG does not Granger-cause PML are mixed. For monthly data, the null hypothesis is rejected when lag = 2; otherwise the null hypothesis cannot be rejected at the significance level of 5%. For quarterly data, the null hypothesis is rejected when lag = 2, 4. The results for filtered data are similar to the unfiltered ones, except that the null hypothesis that PMG does not Granger-cause PML cannot be rejected, and the null hypothesis that PML does not Granger-cause PMG is rejected. This finding is interesting as it indicates an asymmetry between PMG and PML. For monthly data, the historical PML helps to predict PMG but not vice versa; for quarterly Table 3 Autocorrelation Analysis on PMG and PML Filtered Panel A. Monthly Index Data Panel B.

Potential Explanations We demonstrated an asymmetry between PMG and PML in Section 3and the economic value of the asymmetry in Section 4. This section explores whether this asymmetry can be explained by business cycle, technical indicators, skewness, or market sentiment. Business Cycle A business cycle is an asymmetric economic condition that is long in expansion and short in recession. Thus, a potential explanation for asymmetry is that it is correlated with macroeconomic variables related to business cycle. Indeed, Chen, Roll and Ross (1986); Keim and Stambaugh (1986); Campbell and Shiller (1988); Fama and French (1988); Campbell (1991); Ferson and Harvey (1991); Lettau and Ludvigson (2001a, 2001b); and Li (2001) found evidence that the stock market can be predicted by variables related to business cycle, such as default spread, term spread, interest rate, inflation rate, dividend yield, consumption–wealth ratio, and surplus ratio. For the monthly data, 13 representative business-cycle-related predictors were collected for the time period January 1950 to December 2015. The 13 economic variables are the following: Book-to-market ratio, BM. Ratio of book value to market value for the Dow Jones Industrial Average. Dividend-payout ratio (log), D/E. Difference between the log of dividends and the log of earnings. Default yield spread, DFY. Difference between BAAand AAA-rated corporate bond yields. Dividend-price ratio (log), D/P. Difference between the log of dividends paid on the S&P 500 index and the log of stock prices (S&P 500 index), where dividends are measured using a one-year moving sum. Dividend yield (log), D/Y. Difference between the log of dividends and the log of lagged stock prices. Earnings-price ratio (log), E/P. Difference between the log of earnings on the S&P 500 index and the log of stock prices, where earnings are measured using a oneyear moving sum. Inflation, INFL. Calculated from the CPI (all urban consumers). Long-term return, LTR. Return on long-term government bonds. Long-term yield, LTY. Long-term government bond yield. Net equity expansion, NTIS. Ratio of 12-month moving sums of net issues by NYSE-listed stocks to total end-of-year market capitalization of NYSE stocks. Stock variance, SVAR. Sum of squared daily returns on the S&P 500 index. Treasury bill rate, TBL. Interest rate on a three-month Treasury bill (secondary market). Term spread, TMS. Difference between the long-term yield and the Treasury bill rate. For quarterly data, two more predictor variables were collected 3 : Xie and Wang Financial Innovation (2018) 4:30 Page 15 of 24
Investment-to-capital ratio, IK. Ratio of aggregate (private nonresidential fixed) investment to aggregate capital for the entire economy (Cochrane, 1991). CAY. CAY is defined as in Lettau and Ludvigson (2001a). Tables 10 and 11 present, respectively, the summary statistics on correlations for monthly and quarterly data observations. Except SVAR, the results show low correlations between PML (PMG) and business-cycle-related variables. Tables 12 and Table 13 present, respectively, regression results for monthly and quarterly observations with business-cycle-related variables controlled. The regression results show that asymmetry cannot be explained by business-cycle-related variables. Technical Indicators Recent empirical literature has shown that some technical indicators are informative for forecasting stock returns. Huang et al. (2016) constructed two indicators from historical price—the mean reversion indicator and the good time indicator—and found that stock returns can be significantly predicted in both good and bad times. The mean reversion indicator and the good time indicator are defined as follows: Mean reversion indicator, MRI. This indicator has been found to be informative for predicting stock returns (Huang et al., 2016): MRIt¼rt‐12→t‐uðÞ=σt‐12→t; where r t-12→t is the cumulative market return over the past year (from month t-11 to month t), u is the long-term mean (mean of the past 30 years), and σ t-12→t is the annualized moving standard deviation estimator (Mele, 2007). Good time indicator, I MA . This indicator is the 200-day moving average. It takes a value of 1 when the S&P 500 index is above its 200-day moving average (Huang et al., 2016). Table 14 reports the regression results for monthly data in panel A and for quarterly data in panel B. The results show that PML still significantly predicts PMG, even when MRI and IMA are controlled. George and Hwang (2004) and Li and Yu (2012) showed, respectively, that 52-week high and historical high predict stock returns. Following George and Hwang (2004) and Li and Yu (2012), the 52-week high and historical high are presented as follows: Nearness to the Dow 52-week high, H 52 . George and Hwang (2004) suggested that traders might use the 52-week high as an anchor when assessing the increment in stock value implied by new information. Suppose there are 250 trading days in 52 weeks; the nearness to the 52-week high was computed in this study as the ratio of the current S&P 500 index and its 250-day high: H52t¼pt=p250;t; where p t denotes the level of the S&P 500 index at the end of day t, and p 250,t denotes the 250-day high at the end of day t.

and historical-high indicators. The coefficients of filtered bad extreme returns decreased from 0.136 to 0.053 and to 0.021, and became insignificant. For quarterly data observations in panel B, the results show that the 52-week high and historical high only partly explained the asymmetry in covariances. A superior explanation of 52-week high and historical high in relation to asymmetry pertains to the similarities among PML, H 52t ,andH maxt .Allofthesethree indicators are constructed from high price. Actually, the correlation between PML and H 52t (H maxt ) was -0.606 (-0.449) for monthly data and -0.817 (-0.594) for quarterly data. However, the out-of-sample R-squares in Li and Yu (2012)werereported to be 0.1% for monthly data and 0.8% for quarterly data when both nearness to historical high and nearness to 52-week high were used as predictors, which are much smaller than our results. Market Sentiment Baker and Wurgler (2006) constructed an investor sentiment index and found that it had strong forecasting power for a large number of cross-sectional stock returns. Stambaugh, Yu, and Yuan (2012) found that investor sentiment predicted the short legs of long–short investment strategies. Baker, Wurgler, and Yuan (2012) provided further international evidence for the cross-section forecasting power of investor sentiment. Huang et al. (2015) found that an aligned sentiment index had much greater power in predicting the aggregate stock market than the Baker and Wurgler (2006) index. We collected both the sentiment index of Baker and Wurgler (2006) and the aligned sentiment index of Huang et al. (2015) and investigated whether asymmetry could be explained by sentiment. 4 The results are presented in Table 16. Consistently, we found that asymmetry could not be explained by sentiment. Skewness Recent empirical results have shown that skewness predicts stock returns. Among others, Boyer, Mitton, and Vorkink (2010) found that expected idiosyncratic skewness Table 15 Regression with 52-week High and Historical High Controlled Panel A.

and returns were negatively correlated. Amaya and Vasquez (2015) found that skewness from high-frequency data predicted the cross-section of stock returns. Using data on individual stock options, Rehman and Vilkov (2012) found that the currently observed option implied that ex ante skewness is positively related to future stock returns. We constructed the skewness indicator as follows: SKt¼X200 i¼1rtþ1‐i‐ut ðÞ=σt ½ 3=200 ut¼X200 i¼1rtþ1‐i=200 σt¼X200 i¼1rtþ1‐i‐ut ðÞ 2=200; where SK t is the skewness indicator, and r t s are daily log returns. Similar to Huang et al. (2016), we used 200 as the moving window length. Table 17 reports the results, which show that asymmetry cannot be explained by skewness. Global Evidence To see if the asymmetry discovered in this study is only applicable to the US S&P 500 stock index, we also performed a comprehensive empirical study on the main global stock indices. For Asian countries, this included the Chinese Shanghai Stock Exchange Composite index (SSEC), Hongkong Hangseng Index (HS), Taiwan Stock Exchange Corporation index (TSEC), Singapore Strait Times Index (ST), Japanese Nikkei 225 Stock Average Index (NIKKEI 225, NK), Korea Stock Exchange Kospi Index (KOSPI). For European countries, we used the British Financial Times Stock Exchange 100 Index (FTSE 100, FT), German Deutscher Aktien Index (DAX), and French Cotation Assistee en Continu 40 Index (CAC 40, CAC).

Securities Dealers Automated Quotations Index (NASDAQ). All data sets were downloaded from www.finance.yahoo.com. Table 18 reports the Granger causality testing results on PMG and PML when stock returns were decomposed with high price extremes. Almost unanimously, we found that PML Granger-caused PMG but not vice versa. This global evidence indicates that the asymmetric reactions between PMG and PML are general. For robustness, Granger causality tests were also performed when stock returns were decomposed with low price extremes; the results were similar. We didn't report the results for saving space. Conclusions It is well known that price extremes are valuable for estimating and forecasting the volatility of financial assets. However, little is known about whether price extremes contribute to forecasting asset returns. This study decomposed asset returns with price extremes into potential maximum gains (PMG) and potential maximum losses (PML) and empirically investigated the relationship between the two. We found significant asymmetry between PMG and PML. PML had a large impact on the time series dynamics of PMG but not vice versa. This asymmetry cannot be explained by macroeconomic variables, technical indicators, market sentiment, or skewness. We also explored the economic value of this asymmetry and found that investors can significantly improve their utility gains if this asymmetry Table 18 Granger Causality Tests on PMG and PML: Decomposition with High Price Extremes Panel A: Monthly Data Observations Panel B: Quarterly Data Observations Lags 2 4 6 2 4 6 HS: PMG /→PML 0.069 0.033 0.068 0.078 0.551 0.797 HS: PML /→PMG 0.000 0.000 0.001 0.175 0.132 0.155 ST: PMG /→PML 0.924 0.524 0.417 0.726 0.730 0.811 ST: PML ST /→PMG 0.000 0.000 0.000 0.000 0.000 0.000 NK: PMG /→PML 0.463 0.842 0.904 0.815 0.601 0.453 NK: PML /→PMG 0.000 0.000 0.000 0.024 0.075 0.210 FT: PMG /→PML 0.894 0.919 0.304 0.478 0.364 0.501 FT: PML /→PMG 0.000 0.000 0.000 0.006 0.031 0.028 NASDAQ:PMG /→PML 0.001 0.004 0.055 0.614 0.022 0.124 NASDAQ:PML /→PMG 0.000 0.000 0.000 0.000 0.000 0.000 SSEC: PMG /→PML 0.056 0.016 0.006 SSEC: PML /→PMG 0.032 0.080 0.310 TSEC: PMG /→PML 0.719 0.655 0.218 TSEC: PML /→PMG 0.000 0.000 0.000 KOSPI: PMG /→PML 0.055 0.334 0.059 KOSPI: PML /→PMG 0.000 0.000 0.000 DAX : PMG /→PML 0.508 0.944 0.690 DAX: PML /→PMG 0.000 0.000 0.000 CAC: PMG /→PML 0.271 0.328 0.269 CAC: PML /→PMG 0.000 0.000 0.000 Note: X /→Ymeans the null hypothesis that Xdoes not Granger-causes Y.

is used in investment decisions. Moreover, this asymmetry was found to be quite general across the main global stock markets. This study’s findings have some interesting implications. First, there are elaborate intrinsic structures in the dynamics of asset returns, and these structures can hardly be captured by the univariate time series modeling technique. Thus, more subtle models are needed to describe the time series dynamics of asset returns. Second, the information contained in price extremes is valuable for asset pricing. Our future efforts will focus on incorporating price extremes into asset returns modeling and asset pricing.
