Stock Event Strategy Based on Earnings Growth Announcements

Summary

This event-driven equity strategy buys stocks at the open after financial results are announced, selecting companies whose year-over-year net profit attributable to parent shareholders has grown by more than 30%. Eligible stocks are ranked by growth, and the portfolio holds up to 50 positions. Each position is sold after 40 trading days, with the described exit executed at the following day's open. The workflow joins financial data with report publication dates, applies the growth filter and ranking, and removes records with missing data.

The implementation outline also describes tracking entry dates, available cash, transaction fees, and slippage, then allocating available cash in equal proportions among selected stocks. The document explains the intended timing on the assumption that announcements generally arrive after market hours. It offers no reported backtest results, and the text does not clarify how publication timing, restatements, execution constraints, or overlapping holding periods are handled. The thresholds and holding period are strategy choices, not demonstrated evidence of an edge.

Key ideas
