Using Earnings Revisions in Leading Stocks for Industry Rotation
Summary
This report studies whether changes in leading companies’ expected earnings can help select industries for rotation. Its premise is that revisions to a sector leader’s expected fundamentals may influence subsequent returns across related stocks. The analysis constructs signals from changes in forecast EPS and ROE, ranks industries, and evaluates both grouped long-short portfolios and long-only rotation portfolios. It contrasts this approach with using industry-wide earnings revisions, which the report says tend to follow the initial move in sector returns rather than anticipate it.
The reported evidence includes positive associations between leaders’ forecast revisions and next-month industry returns, along with positive results for portfolios formed on EPS and ROE changes. A combined strategy using historical ROE information is reported to distribute excess returns more evenly than the single-factor version. The excerpt does not provide the full underlying tables or a complete specification of the data and portfolio construction, and one reported correlation value is missing. The authors warn that historical relationships can change and statistical models can fail.
Key ideas
- Industry-wide forecast revisions may lag the start of sector returns, limiting their use as a timely rotation signal.
- Upward EPS revisions for industry leaders are associated with stronger subsequent industry returns in the report’s analysis.
- ROE revisions are tested as an alternative earnings signal and also show reported industry-selection value.
- Combining current and historical ROE information is reported to spread excess returns more evenly.
- The evidence is historical, and the excerpt omits some model details and one correlation statistic.
