ABSTRACT When coupled with a stock's current price, a readily available piece of information—the 52‐week high price–explains a large portion of the profits from momentum investing. Nearness to the 52‐week high dominates and improves upon the forecasting power of past returns (both individual and industry returns) for future returns. Future returns forecast using the 52‐week high do not reverse in the long run. These results indicate that short‐term momentum and long‐term reversals are largely separate phenomena, which presents a challenge to current theory that models these aspects of security returns as integrated components of the market's response to news.

We examine whether and how managers use loan loss provisions to smooth income and to signal their private information about their banks' future prospects. Our paper highlights that the use of the loan loss provision to accomplish more than one objective gives rise to situation‐specific costs and benefits of manipulating the provision up or down. We hypothesize that relatively undervalued banks have greater incentives to signal their future prospects than fairly valued banks and that banks' incentives to smooth intensify as premanaged earnings deviate from norms. On the basis of these conjectures, we categorize sample banks into subgroups that are predicted to use loan loss provisions consistent with their situation‐specific incentives. This allows us to refine the research methods used in prior research to examine heterogeneous incentives. While we find evidence consistent with the use of loan loss provisions to smooth earnings, particularly when premanaged earnings are extreme, our evidence on signaling is less consistent. In particular, our signaling results depend on the introduction of an interaction term that has not been used in prior research. We also document that the intensity of smoothing (signaling) is not uniform across the sample. In addition to being a function of the incentive to smooth (signal), it also is a function of the incentive to signal (smooth).

This paper compares the comovement of individual stock returns across emerging markets. Campbell et al. and Morck et al. have shown that the United States saw rising firm-specific stock return variations, and thus declining comovement, over the second half of the twentieth century. We detect a similar, albeit weaker, pattern in most, but not all, emerging markets. We further find that higher firm-specific variation is associated with greater capital market openness, but not goods market openness. Moreover, this relationship is magnified by institutional integrity (good government). Goods market openness is associated with higher marketwide variation.
