All-Time High Breakouts in U.S. Stocks with ATR Trailing Stops

Summary

This strategy selects liquid U.S.-listed stocks above a minimum price and enters when a stock’s closing price reaches or exceeds its previous highest close. It holds qualifying positions in an equally weighted portfolio, adjusts allocations daily, and uses a trailing stop based on a 10-period average true range. The implementation describes a universe of the 100 most liquid stocks, a long historical lookback for highs, and transaction cost assumptions intended to reflect commissions and slippage.

The document provides implementation details rather than performance evidence: it gives no backtest results, benchmark, or evaluation of risk-adjusted returns. The code’s universe selection, history lookback, signal tracking, and position counting may affect how the stated strategy behaves in practice. Its stated cost assumption is not necessarily representative of actual trading, and the stop and portfolio rules would need careful validation before drawing conclusions about effectiveness.

Key ideas

• The entry signal is a closing price at or above the stock’s recorded historical closing high.
• The described universe favors higher-priced, liquid U.S. stocks.
• A 10-period average true range informs the trailing exit stop.
• The portfolio is equally weighted and rebalanced daily, with transaction costs accounted for in the strategy description.
• The document supplies code but no results establishing profitability or robustness.
