Why Did Individual Stocks Become More Volatile?*

Open access
Wei, Steven X., Zhang, Chu·2006·The Journal of Business

Abstract

The fact that stocks become more volatile on average is documented by Campbell et al (2001) and Morck et al (2000) for the U.S. since 1960s. In this paper, we investigate why individual stocks become more volatile. Our inquiry focuses on the 1976-2000 period during which quarterly accounting data are available at the firm level. We report that corporate earnings have deteriorated on average and their volatility has increased over the sample period. This is more evident for newly listed stocks than for existing stocks. The stock return volatility is negatively related to the return-on-equity (scaled earnings) and positively related to the volatility of the return-on-equity in cross-sections. The upward trend in average stock return volatility is fully accounted for by the downward trend in the return-on-equity and the upward trend in the volatility of the return-on-equity. Other variables that have cross-sectional explanatory power, such as firm equity size and firm age, do not contribute to the increase of stock return over time.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
