Model Overview - The strategy is based on a deviation correction model with a callback-type stop-loss mechanism, assuming a cyclical deviation-regression pattern in the price movements of the target relative to a benchmark [4][5] - The model uses historical drawdown data to determine buy thresholds and employs a tiered stop-loss system once a buy signal is triggered [4][5] Performance Evaluation - Total return of the strategy during the backtest period (January 4, 2010 - March 18, 2025) was 108.52% [4] - The buy-and-hold return for the target was 152.35%, resulting in an excess return of -43.84% [4] - The maximum drawdown recorded was 51.27%, with the longest drawdown period lasting 2261 trading days [4] Strategy Applicability - The strategy was tested with a parameter of X=7 and is noted to be less effective in the computer industry, which is characterized by long-term volatility and occasional explosive growth due to technological iterations [5]
