Screening Main Board Stocks by RSI, Daily Gain, and Recent Limit-Up

Summary

The document presents a daily stock screen combining a relative strength index below 65, a gain greater than 1% on the current day, main-board membership, and at least one limit-up move during the preceding month. It frames these filters as a way to find stocks with positive short-term movement and recent market attention. The limit-up condition is illustrated using a price-change threshold and a lookback of 22 trading sessions; a Python example describes retrieving market and historical data, applying the filters, and returning selected stock fields.

The article cautions that simple screening rules can produce false signals, that recent sharp advances may be followed by volatile trading, and that changing earnings or market themes can undermine a selection. It suggests adding other indicators or market-capitalization criteria and monitoring exposure. These are screening ideas, not a tested trading system: the document supplies no performance analysis, and its asserted links between limit-up moves, company quality, and institutional interest are not substantiated with evidence.

Key ideas

• The screen requires an RSI below 65 and a current-day gain above 1%.
• It restricts candidates to main-board stocks with a limit-up move in the past month.
• The example counts qualifying limit-up events over 22 trading sessions.
• The article notes that the filters may miss changing fundamentals and may select stocks vulnerable to volatility.
• It suggests adding indicators or capitalization filters, but provides no strategy performance evidence.
