An Anatomy of Trading Strategies: Evidence from China

Using a pooled cross-sectional time series approach, we evaluate profits of momentum strategies and identify the sources of profits in China's stock market. Momentum strategies generate significant and negative returns in the A-share market on investment horizons at one month and at and above nine months. In the B-share market, momentum strategies yield significant and negative returns at and above twelve months. Decomposition analysis finds that the negative returns are predominately attributed to the time series profitability of stock returns. Although momentum strategies generate significant and positive returns over the period after China opened its once foreign-restricted B-share market to domestic individual investors, the relative importance of the time series predictability and the cross-sectional variation does not change.

CEO/CFO turnover and subsequent remediation of information technology material weaknesses

Adding to prior research on internal control material weaknesses (ICMW), our study investigates whether information technology material weaknesses (ITMWs) are associated with CEO/CFO turnover, and whether their turnover will promote subsequent remediation. We find that disclosures of ITMW are positively associated with CEO/CFO turnover; however, only CEO turnover promotes subsequent remediation. Our findings on ITMW are different from the prior findings on ICMW – aligned with prior research on ICMW, ITMWs are associated with CEO/CFO turnover; however, unlike prior research on ICMW suggests, dismissals of CFOs do not promote subsequent remediation of ITMW. Thus, future research should consider ICMW and ITMW separately in the examination of their consequences and remediation.
