The macroeconomic regime matters. Regardless of style, if you tilt to industries that have historically had higher Sharpe ratios in different economic regimes, investors can add value to their portfolio. Call it industry business cycle rotation, but accounting for simple macro regimes to industry allocations will improve portfolio performance.
Industries will perform differently across the business cycle, but many have viewed that predicting the macro regime is difficult. A careful research paper takes a relatively simple approach to address this problem and show macro timing value. (See "Does History Repeat Itself? Business Cycle and Industry Returns".)
Industry Sharpe ratios can be categorized across business cycle regimes. Given this information, the researchers make a judgement of the macro regime based on the output gap at the end of the year for the next year. Sorting the industries between long and short portfolios, it is found that buying high Sharpe ratio industries conditional on regime will outperform the market portfolio and a short portfolio.
