The expansion of investment strategies and capital markets is altering the significance and empirical rationality of the Efficient Market Hypothesis. The vitality of capital markets is essential for efficiency research. The authors explore here the development and contemporary status of the efficient market hypothesis by emphasizing anomaly/excess returns. Investors often fail to get excess returns; however, thus far, market anomalies have been witnessed and stock prices have diverged from their intrinsic value. This paper presents an analysis of anomaly returns in the presence of the theory of the efficient market. Moreover, the market efficiency progression is reviewed and its present status is explored. Finally, the authors provide enough evidence of a data snooping issue, which violates and challenges the existing proof and creates room for replication studies in modern finance.

This paper explores the relationship between media coverage and stock returns using monthly data of news reports from major Chinese newspapers. We find that firms with higher media coverage in the current month have higher sustainable stock returns in the following months over a one-year period compared with those with lower media coverage, which means that media coverage has a more significant and positive influence on sustainable stock returns in the markets, dominated by individual/immature investors. These results are largely robust to various robustness checks. Further empirical results demonstrate that in the Chinese stock market, a higher level of media coverage might cause higher sustained investor attention, which may drive up the buying pressure and thus lead to higher sustainable stock returns in the following year. Our results show that the effect of media coverage on stock returns depends on the characteristics of investors.

This study examines the impact of regulatory capital requirements and ownership structure on bank lending in Emerging Asian Markets. The findings of the study imply that banks with excess capital are less affected by capital constraints and enjoy opportunities to extend their credit portfolios. The monitory policy indicator has the expected negative and significant impact on bank lending. In case of well-capitalized banks, the interaction between the excess capital and monetary policy indicator has a significant positive relation with bank lending, which means that banks with excess capital have capability to raise uninsured financing and shield their loan portfolios as compared to less-capitalized banks that reduce their lending in the period of monetary tightening. In the case of bank ownership structure, banks with excess capital ratios and ownership concentration lead towards an increase in lending activity. The findings also show that well-capitalized banks with managerial ownership tend to reduce lending which validates agency theory of corporate governance.

This paper uncovers a new finding of sustainable cross-sectional variations in stock returns explained by mood fluctuations across the days of the week. Long/short leg of illiquid anomaly returns are extensively related to the days of the week, and the magnitude of excess returns is also striking [Long leg refers to portfolio deciles that earn higher excess returns. Historical evidence suggests that more illiquid stock earn higher excess returns (Amihud, 2002; Corwin and Schultz, 2012)]. The speculative leg of illiquid anomalies is the long leg (Birru, 2018) [The speculative leg falls into the long leg of anomaly because more illiquid stocks are sensitive to investor sentiment (Birru, 2018)]. Therefore, the long (speculative) leg experiences more sustainable high returns on Friday than the short (non-speculative) leg. At the same time, relatively higher long (speculative) leg returns were witnessed on Friday than Monday with a greater magnitude difference. These cross-sectional variations in illiquid stocks on specific days are consistent with the explanation of the limit to arbitrage. The observed variations in cross-sectional returns are sustained and consistent with plenty of evidence from psychology research regarding the low mood on Monday and high mood on Friday.
