Backtesting Earnings Growth Events in Chinese Equities

Summary

This article outlines an event-driven strategy for Chinese equities, using quarterly reports as the trigger. It treats a published year-over-year increase of more than 30% in attributable net income as a positive event, buys qualifying stocks when reported, holds each position for up to 40 trading days, and caps the portfolio at 50 holdings. The approach checks for new qualifying disclosures each day. The article also describes other possible event categories, including earnings forecasts, dividends, insider transactions, share unlocks, restructurings, and rating changes.

The author reports that the backtest showed a positive long-term return profile, but supplies no detailed performance figures or methodology in the text. Exposure can remain below full investment because qualifying reports do not arrive continuously. The article says orders are dated one day before the stated disclosure date to reflect an assumption that reports are released the prior evening. That timing convention, data availability, transaction costs, and survivorship or reporting biases could affect whether results carry over to live trading. The discussion of ST Intercontinental is background, not the tested signal.

Key ideas

• The strategy buys companies after quarterly attributable net income growth exceeds 30% year over year.
• Positions are held for up to 40 trading days, with no more than 50 stocks held at once.
• The backtest is described as producing long-term positive returns, but detailed performance evidence is absent from the text.
• Portfolio exposure varies because qualifying earnings disclosures are intermittent.
• The backtest places orders a day before the listed disclosure date based on an assumed evening release.
