Chinese Stock Screening with a Rising 30-Day Average and Auction Volume

Summary

This stock screen combines a rising 30-day moving average with a measure of trading activity. It ranks candidates by a proposed capital-strength measure: yesterday’s turnover rate multiplied by today’s opening-auction volume divided by yesterday’s volume. The stated filter keeps values above 0.5 and below 2, aiming to select stocks with moderate activity alongside an upward trend. The discussion also mentions turnover and auction volume as indicators of stock activity.

The document offers a rationale and possible refinements, but no historical test, performance data, or detailed definition of how the inputs are calculated. It cautions that moderate activity and an upward moving average do not ensure a price increase, since other factors can change a stock’s direction. The proposed screen is therefore an illustrative selection rule rather than evidence of a validated trading strategy.

Key ideas

• The screen looks for stocks whose 30-day moving average is rising.
• It ranks stocks using yesterday’s turnover rate and the ratio of today’s auction volume to yesterday’s volume.
• The proposed capital-strength filter is greater than 0.5 and less than 2.
• The document suggests adding other activity and trend measures, but provides no backtest evidence.
