We study how market sentiment is dynamically related to a range of risk premia in the short-run, using three measures of sentiment (the implied volatility index, investment advisor sentiment, and individual investor sentiment) and four factor premia (market, size, value, and momentum) for the...

This paper examines return predictability of the U.S. stock market using portfolios sorted by size, book-to-market ratio, and industry. A novel panel variance ratio test is proposed and employed to evaluate time-varying return predictability from 1964 to 2011. It is found that the stock returns...

We evaluate the empirical validity of popular asset-pricing models in explicit consideration of statistical power, by employing the adaptive significance level and equal-probability test. Past studies often use samples from a large cross-section of portfolios over a long time period, conducting...

We conduct the extreme bounds analysis (EBA) to evaluate the robustness or fragility of a range of stock market anomalies, using U.S. daily data from 1960. The EBA is a large-scale sensitivity analysis, able to isolate the effects of potential data-mining or p-hacking under model uncertainty....

We study return predictability of the Dow Jones Industrial Average indices from 1900 to 2009. We find strong evidence that time-varying return predictability is driven by changing market conditions, consistent with the implications of the adaptive markets hypothesis. During market crashes, no...

This study measures the degree of short-horizon return predictability of 50 international equity markets and examines how its variation is related to the indicators of equity market development. Two multiple-horizon variance ratio tests are employed to measure the degree of return...

Evidence of a negative relationship between extreme positive returns and future returns has been reported in developed markets; a result that has been attributed to mispricing (Bali, Cakici, & Whitelaw, 2011; Zhong & Gray, 2016). This study examines this MAX anomaly across advanced emerging markets,...

Despite an extensive number of studies documenting evidence of seasonal anomalies in developed markets, only a few studies have comprehensively examined these anomalies within emerging markets. Testing the robustness of seasonal anomalies in emerging markets would first, help to examine the...
