Combining Industry Momentum and Valuation in Index Enhancement

Summary

This research tests Chinese industry rotation signals based on cross-sectional momentum and valuation. It reports stronger industry momentum over a one-month lookback and compares industries grouped by the percentile of their current valuation relative to their own history. The high-valuation group is reported to outperform the low-valuation group by 6.90% annualized excess return.

The combined model assigns industries in the bottom third for both momentum and valuation to a short group and the remainder to a long group. Its long-short portfolio is reported at 8.68% annualized return, a 0.93 information ratio, and a 67.74% monthly win rate. For index enhancement, it trims short-group benchmark weights and redistributes them equally among long-group industries. The reported annualized excess return rises by 0.54 percentage points for CSI 500 enhancement and 0.47 points for CSI 300 enhancement versus industry-neutral versions. These are historical test results; the report cautions that market structure can change and past performance may not persist.

Key ideas

• The study finds stronger cross-sectional industry momentum with a one-month lookback.
• It measures industry valuation as a percentile of each industry's historical valuation range.
• Industries ranked in the bottom third on both momentum and valuation form the short group, while the rest form the long group.
• The model reduces benchmark weights in short-group industries and reallocates the removed weight equally to long-group industries.
• Historical tests report improved excess returns for CSI 500 and CSI 300 index enhancement, with market-structure change as a key limitation.
