Screening Chinese Mainboard Stocks by Range, Market Value, and Profitability
Summary
The screen targets Chinese stocks whose tickers begin with 60, with daily high-low range above 1%, market value no greater than 10 billion yuan, and positive net profits in each of the latest four quarters. It combines a price-activity filter with a size limit and a basic profitability requirement. The document includes example formula and Python-style implementation references, but reports no backtest, sample results, or evidence that the criteria predict returns.
The author notes that the filters may leave few candidates, exclude newer listings, and encourage short-term speculation if technical activity receives too much weight. Suggested refinements include considering valuation and return-on-equity measures, broadening the eligible ticker set, adding other market and technical indicators, and reviewing company history. The proposed final screen also mentions market heat, position limits, and stop-losses without defining their calculations. These additions are suggestions rather than tested components, and the document gives no rules for execution or portfolio construction.
