New Evidence on Stock Price Effects Associated with Changes in the S&P 500 Index

Lynch, Anthony W., Mendenhall, Richard R.·1997·The Journal of Business

Abstract

Since October 1989, Standard and Poor's has (when possible) announced changes in the composition of the S&P 500 index one week in advance. Because index funds hold S&P 500 stocks to minimize tracking error, index composition changes since this date provide an opportunity to examine the market reaction to an anticipated change in the demand for a stock. Using post-October 1989 data, the authors document significantly positive (negative) postannouncement abnormal returns that are only partially reversed following additions (deletions). These results indicate the existence of temporary price pressing and downward-sloping long-run demand curves for stocks and represent a violation of market efficiency.

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.
