Screening Newer Stocks by Auction Value and Daily Price Range

Summary

This Chinese equity screening note combines three conditions: daily price amplitude greater than 1, ranking among the five highest stocks by that day’s auction value, and listing in 2021. The stated rationale is that a larger range may accompany greater upside potential, while high auction value is intended to avoid names with very little trading activity. Recent listings are treated as a possible source of investment opportunities. The note includes formula and Python examples, although parts of the code do not clearly implement the stated ranking and listing criteria.

The strategy is a selection rule rather than a complete entry and exit system. It does not describe a holding period, position sizing, or risk controls, and it explicitly notes that it ignores company fundamentals. Its suggested refinements include adding valuation and industry measures and choosing an appropriate evaluation period. No backtest or performance evidence is reported, so the proposed link between range, auction activity, and opportunity is not demonstrated. The screen may also concentrate exposure in newer, more volatile stocks.

Key ideas

• The screen selects stocks with daily amplitude above 1, high auction value, and a 2021 listing year.
• The author treats auction value as a way to favor stocks with more trading activity.
• The rule omits company fundamentals and does not specify a full trade-management process.
• Valuation and industry indicators are suggested as additions to the screen.
• No backtest or quantified evidence is given to support the proposed opportunity rationale.
