Screening for Volatile Stocks with Recent Large Daily Gains

Summary

This proposed stock screen combines an amplitude threshold above 1, a listing age greater than one year, and at least one daily gain of 10% or more during the previous 25 trading days. The post treats a recent large gain as evidence of short-term strength and includes amplitude and listing age as additional filters. It also outlines a formula and data-based selection procedure, but gives no backtest or realized performance results.

The article warns that a single sharp rise may reflect a temporary spike rather than a durable trend, leaving selected stocks exposed to reversals. It recommends considering trading volume and conducting broader research to assess longer-term prospects. The supplied text has some specification limits: the amplitude unit and precise calculation are not explained, and the sample-data procedure’s date handling does not clearly match a 25-trading-day window. This is best read as a screening idea that needs validation, rather than a complete trading strategy.

Key ideas

• The screen requires amplitude above 1 and more than one year since listing.
• A stock qualifies if it had a daily gain of at least 10% during the prior 25 trading days.
• The post gives no test results or evidence that the conditions predict future returns.
• A sharp recent gain may be temporary and expose a selected stock to reversal risk.
• Volume and broader company research are proposed as additional checks.
