Small-Cap Equity Screening with Profitability and Limit-Down Signals

Summary

This note outlines a stock screen for companies with positive net profit and market capitalization below a stated ceiling, combined with a daily amplitude threshold and a prior-day 9:15 matching-price condition described as limit-down behavior. The article interprets smaller capitalization as potential growth, positive profit as a quality filter, and the opening-price signal as possible short-term pressure that could precede a rebound.

It offers example screening expressions and a Python-style sketch, but the matching-price condition in the examples appears to compare a value with a fraction of itself, so the implementation may not capture the stated signal. No historical performance data or validation is presented. The article warns that high volatility and short-term pressure can indicate risk, while a narrow screen can ignore longer-term trends, valuation, and fundamentals. It suggests combining broader measures such as profitability growth, valuation, and trend context, without demonstrating that these improve results.

Key ideas

• The proposed screen combines price amplitude, a market-cap ceiling, positive earnings, and a prior opening matching-price signal.
• The article treats the opening signal as possible short-term pressure that might be followed by a rebound.
• The example condition for the matching-price signal appears internally inconsistent with its description.
• No backtest or evidence of profitability is provided, and the screen may omit broader financial and trend information.
