The persistence of earnings per share

The persistence of earnings per share The persistence of innovations to accounting earnings per share, EPS, has important implications for equity valuation, yet it remains a largely neglected subject.

Abstract

The persistence of innovations to accounting earnings per share, EPS, has important implications for equity valuation, yet it remains a largely neglected subject. This paper employs various empirical tests in order to measure the persistence of shocks to EPS for the S&P 500 index. Within the I(0)/I(1) paradigm the empirical evidence rejects the I(1) specification, supporting instead a trend-stationary representation. When fractional orders of integration are considered, the results indicate that the detrended series is long memory (d  >  0) and mean reverting (d < 1). The responses decay slowly to zero, albeit 50 quarters after an initial shock the responses remain significantly different from zero. Likewise, the variance ratio evidence suggests that the effect of a shock persists over time spans characteristic of the business cycle.
