融入全球化的中国：世界生产贸易大逆转及其原因剖析

16世纪以后，以中国为代表的东方文明和西方文明出现分野，东方的科学技术越来越落后子西方，历史称之为“李约瑟之迷”，进入21世纪后，中国正在以前所未有的速度走出这个迷团。2011年，中国制造业产值为2．05万亿美元，而美国制造业为1．78万亿美元，首次超过美国成为全球第一，贸易也是如此，2012年中国货物进出口总额38670亿美元，美国为38628亿美元，也已经超过美国成为世界第一。分析这个大逆转的厚因，一是从体制上解放了了生产力，社会主义市场经济体制是人类社会主义伟大实践的创举；二是对外开放；三是坚定不移地贯彻了科学技术是第一生产力的伟大国策；四是融入了了全球的货币体系。     

Short-term overreaction to specific events: Evidence from an emerging market

This paper investigates the short-term overreaction to specific events and whether stock prices are predictable in the Egyptian stock exchange (EGX). We find evidence of the short-term overreaction in the EGX. Losers (“bad news” portfolios) significantly outperform winners (“good news” portfolios) and investors can earn abnormal return by selling the winners and buying losers. Terrorist attacks have negative and significant abnormal returns for three days post event followed by price reversals on day four post event. Whereas, the tensions in the Middle East region have a negative and significant abnormal returns on event day followed by price reversals on day one post event. Moreover, the formation of a new government has no effect on the average abnormal returns post event in the EGX. The results also show that small firms tend to have greater price reversals compared to large firms. Overall, our results provide evidence of the leakage of information in the EGX.     

The long-run reversal in the long run: Insights from two centuries of international equity returns

We perform the most comprehensive test of long-term reversal in national equity indices ever done. Having examined data from 71 countries for the years 1830 through 2019, we demonstrate a strong reversal pattern: the past long-term return negatively predicts future performance. The phenomenon is not subsumed by other established cross-sectional return patterns, including the value effect. The long-term reversal is robust to many considerations but highly unstable through time. Finally, our findings support the overreaction explanation of this anomaly.     

The Expiration Effects of Stock-Index Derivatives: Empirical Evidence from the Taiwan Futures Exchange

Five index derivatives with the same expiration days, settlement days, and settlement systems have been consecutively traded on the Taiwan Futures Exchange (TAIFEX) since 1998. This paper examines the expiration effects of TAIFEX index derivatives on the underlying stock market between 1998 and 2002. Our empirical findings show no significant expiration effects on the expiration day, but evidence demonstrates that expiration effects have strengthened as more relative index derivatives are listed on the TAIFEX. Meanwhile, the expiration effects seem to shift to the opening of the settlement day. In general, the expiration effects in Taiwan are not as significant as those in U.S. markets but are stronger than those in the Hong Kong market. The special settlement procedures adopted by the TAIFEX may account for the difference.     

The Beauty Contest and Short‐Term Trading

Short‐termism need not breed informational price inefficiency even when generating beauty contests. We demonstrate this claim in a two‐period market with persistent liquidity trading and risk‐averse, privately informed, short‐term investors and find that prices reflect average expectations about fundamentals and liquidity trading. Informed investors engage in “retrospective” learning to reassess inferences (about fundamentals) made during the trading game's early stages. This behavior introduces strategic complementarities in the use of information and can yield two stable equilibria that can be ranked in terms of liquidity, volatility, and informational efficiency. We derive implications that explain market anomalies as well as empirical regularities.

The market under-and-overreaction story

Using non-overlapping historical monthly returns from 1963 to 2007, this study shows that a trading portfolio that goes long on past winning stocks and short on prior losing stocks earns an average monthly return of 0.88 percent over the ensuing 12 months. However, this momentum profit is entirely wiped out by subsequent return reversals, particularly in the second and third post-formation years. A result of the three-factor Fama and French regression extended by the market momentum effect shows that the Year 1 return and the long-term price reversal （returns in Year 2 through Year 5） move in diametrically opposing directions. This evidence indicates that the market under-and-overreaction anomalies are a manifestation of a market overreaction.     

Institutional herding and its price impact: Evidence from the corporate bond market

We examine the extent to which institutional investors herd in the U.S. corporate bond market and the price impact of their herding behavior. We find that the level of institutional herding in corporate bonds is substantially higher than what is documented for equities, and that sell herding is much stronger and more persistent than buy herding. The price impact of herding is also highly asymmetric. While buy herding facilitates price discovery, sell herding causes transitory yet large price distortions. Such price destabilizing effect of sell herding is particularly pronounced for speculative-grade, small, and illiquid bonds, and during the financial crisis.
