Building and Testing a Multi-Rule Oversold Stock Strategy

Summary

This article describes a customizable stock selection strategy built from five rules, chiefly intended to identify oversold shares that may be stabilizing, with some rules aimed at possible upward moves. It contrasts AI-generated strategies, which are easier to start with but harder to interpret and tune, with coded rules that are more transparent and easier to modify but require programming. The shared implementation is described as holding positions for two days and concentrating heavily in one stock.

The suggested workflow is to define factors and combinations, test individual selection rules, inspect daily holdings and returns, investigate both winners and losers, and then check whether results persist over a different backtest period. The article reports a historical annualized return of 112% and cumulative two-year return of 327%, but offers no detailed assumptions, benchmarks, costs, drawdowns, or independent validation. It also flags that the article and implementation are outdated, so the figures should not be treated as current or as evidence of future performance.

Key ideas

• The strategy combines five stock selection rules focused mainly on oversold shares that may be stabilizing.
• Coded selection rules are presented as more transparent and tunable than an automatically trained AI strategy, though harder to begin using.
• The suggested research process tests rules individually, reviews winners and losers, and checks results on another period.
• The described implementation holds positions for two days and concentrates heavily in one stock.
• Reported returns lack supporting test assumptions and the source marks its implementation as outdated.
