The institutional grade mean-reversion strategy trades the S&P 100 stocks in short-term long-only mode. Backtests show that the strategy has had robust performance, especially during major stock market corrections and it has outperformed the S&P 500 total return by a very wide margin on both absolute and risk-adjusted basis.
The strategy (MRSP100) is long-only with entry signals generated based on our proprietary PSI5 algo also used in our mean-reversion signal service with no changes in the parameters. A maximum of 30 open positions can be held at a time but this rarely happens. The strategy shows superior absolute and risk-adjusted returns with no losing years since 2000 based on backtest results. Note that this is not a data-mined strategy but based on a mathematical model of stock price action. Risk management is very conservative with position size of all trades set equal to one hundredth of available equity in order to avoid equity curve-fitting and selection bias.
