Screening Shenzhen Main Board Stocks by Recent Returns and Valuation

Summary

This document outlines a Chinese stock screen combining a reported increase in buying activity, Shenzhen main-board membership, valuation limits, and a positive but capped 10-day return. It also specifies price-to-earnings and price-to-book ranges. The accompanying explanation interprets increased buying as a possible sign of fund inflows and the valuation bounds as a way to focus on comparatively lower-valued stocks. A partial Python example shows how market data might be filtered, but the code is truncated and does not fully demonstrate the stated rules.

No backtest or return evidence is presented, and the buying-activity measure is not validated as a predictor. The text cautions that the screen cannot reliably forecast market direction and may omit important company financial and operating conditions. It suggests adding profitability, leverage, and technical indicators, while leaving implementation details and portfolio or exit rules unspecified.

Key ideas

• The proposed screen combines buying activity, Shenzhen main-board membership, valuation bounds, and a capped positive 10-day return.
• The valuation conditions use both price-to-earnings and price-to-book ratios.
• The code example is incomplete and does not establish that every stated condition is implemented correctly.
• The document provides no evidence of profitability and notes that company fundamentals and market direction remain sources of risk.
