MACD, Stochastic Oversold, and Company Filters for Stock Selection

Summary

This note describes a stock screening rule that combines a positive MACD reading, a company or concept filter, and a stochastic K value below 20. The intended logic is to select shares with an upward trend signal while looking for an oversold condition that might precede a rebound. The article also gives a formula example and Python-oriented implementation guidance, then suggests adding valuation or profitability measures and adjusting the K threshold.

Its explanation is conceptual rather than empirical: it provides no backtest, return series, benchmark, or validation of the proposed signals. A low stochastic reading can persist during a decline, and a positive MACD reading does not ensure continued gains. The company filter is not clearly defined in the prose, while the formula example refers to a new-energy-vehicle concept. Readers would need to resolve that ambiguity and test the screen with point-in-time data, transaction costs, and a defined portfolio method.

Key ideas

• A positive MACD value is used as a filter for shares with an upward trend signal.
• A stochastic K value below 20 is treated as an oversold condition that may offer rebound potential.
• The company or concept filter is underspecified in the prose and should be defined before implementation.
• The article offers no performance evidence, and oversold readings can occur during continuing declines.
