A Metaverse Stock Screen with Contradictory Concentration Filters

Summary

This post describes an A-share stock screen combining membership in the metaverse theme with a close above the previous day’s low. It also specifies a 21-period concentration ratio that must be at least 70 and below 20, an impossible condition, so the stated rules cannot select any stocks. The same contradiction appears in the indicator and Python examples.

The accompanying discussion presents the price comparison as a short-term strength filter and suggests considering financial measures, market capitalization, and value measures to broaden the screen. It provides no performance data or evidence that the strategy works. The screening logic is therefore mainly an example of how a poorly specified condition can invalidate a strategy; the concentration thresholds must be corrected before the screen is usable. The post also mentions position allocation and a stop level in sample code, but those do not resolve the selection problem.

Key ideas

• The screen combines metaverse theme membership with a close above the prior session’s low.
• The concentration condition requires a value to be both at least 70 and below 20, making the screen unsatisfiable.
• The post offers no backtest results or evidence of profitability.
• It suggests adding financial and valuation measures to complement concentration.
