Does the Stock Market See a Zero or Small Positive Earnings Surprise as a Red Flag?
研究发现，在2000年代早期和中期，盈余惊喜在0到1美分范围内的盈余反应系数显著低于相邻范围，表明投资者对此类惊喜持怀疑态度，且未来盈余惊喜与当前惊喜的负相关关系更强。
ABSTRACT This study shows that firms collectively incur a cost for managing earnings and analyst expectations to meet earnings forecasts. We compare the coefficient in the regression of abnormal stock returns on earnings surprise (the earnings response coefficient [ERC]) across ranges of earnings surprises. The ERC for earnings surprises in the range [0, 1¢] is significantly lower than ERCs for earnings surprises in adjacent ranges for firm‐quarters in the early and mid 2000s, but not for those in the 1990s. The results are robust to controlling for the sign of estimated discretionary accruals and the trajectory of analyst earnings forecasts. We further find that investors are right to be skeptical about earnings surprises in the range [0, 1¢]. The relation of future earnings surprise with current earnings surprise is more negative for current earnings surprises in that range than for those in any other range. Evidence also suggests analysts react negatively to earnings surprises in that range.
