SPX statistical arbitrage
The expected move in the S&P 500 for the next 35 days is approximately 5%, which is considered a one standard deviation move. If the price breaks through this level, it indicates a significant deviation from the expected range, and the trade should be exited to avoid further losses. This approach is based on statistical analysis of market movements and assumes that the market will revert to the mean within the given time frame.
