2021 A-Share Factor Rotation, Strategy Ideas, and Hedging Conditions

Summary

This market review describes a year of changing styles in Chinese equities: cyclical and growth themes led during the recovery, followed by a shift toward value later in the year. It argues that a high earnings base and flattening growth expectations could weaken growth and profitability factors, while factor performance showed tension between fundamentals and value. Proposed stock-selection directions include relative-value approaches, expected high-payout shares, A/H premium models, and earnings-surprise strategies based on analyst forecast differences or improving results.

The report also outlines a lower-frequency deep-learning approach that uses a weighted information-coefficient objective, plus an ETF allocation framework scoring earnings trends, price trends, and institutional behavior. It reports historical excess-return, information-ratio, and drawdown figures for these strategies, alongside futures and options hedging-cost observations. These are period-specific results and conditions, not guarantees of future performance; the review flags model risk, major shifts in expectations, and policy changes. Its detailed conclusions depend on the 2021 market regime and the cited test periods.
