Screening 2021-Listed Stocks by Amplitude and Listing Age

Summary

This stock-selection note proposes screening for shares with price amplitude above one, a listing age greater than a year, and a listing year of 2021. The rationale offered is that newer listings may attract more market attention and could have stronger prospects than older stocks. It suggests adding growth, valuation, or business-condition measures to refine the candidate set, and considering relative volatility when looking for potential breakouts.

The accompanying Python example obtains listed-stock records and recent daily prices, filters by listing date and year, then calculates a high-low range relative to the prior close. It does not complete the final selection step: the code leaves additional filters as a placeholder and returns a list without defining ranking or position rules. The note warns that newer stocks may have weak liquidity or small market values, and that poor overall market conditions can still produce losses. No backtest, return figures, or validation evidence is supplied, so the screen is a hypothesis rather than a demonstrated strategy.

Key ideas

• The proposed screen combines a minimum amplitude threshold with listing age and a 2021 listing year.
• The example estimates amplitude from the daily high-low range relative to the prior close.
• Growth, valuation, and business measures are suggested as possible additional filters.
• New listings may have low liquidity or small market values, and market declines can still cause losses.
• The code leaves the final selection criteria incomplete and reports no tested performance.
