Moving-Average Alignment, Limit-Up History, and Trend Filters

Summary

This document outlines a Chinese equity screen using three conditions: at least five moving averages overlap, the stock has reached the daily price limit at least twice within 500 days, and its 30-day average is rising. It explains the averages as indicators of price behavior over different horizons and interprets their convergence as relatively stable recent trading. Past limit-up moves are treated as a sign of buying interest, while the rising average is intended to capture an upward trend. The final rules also add price-to-earnings below 20 and price-to-book below 2.

These interpretations are hypotheses rather than demonstrated results: the document supplies no backtest or performance data, and its sample code is incomplete. It flags limited attention to longer-term price behavior and company fundamentals, and suggests adding longer moving averages and valuation measures. The screen may therefore need validation and more complete implementation before its usefulness can be assessed.

Key ideas

• The screen combines overlapping moving averages, repeated limit-up events, and a rising 30-day average.
• The final selection rules add price-to-earnings and price-to-book thresholds.
• The document interprets average convergence as price stability and limit-up history as evidence of buying interest.
• No empirical results are given, and the code excerpt is incomplete.
