SPX Strangle - High Loss Threshold - 52 DTE

This post looks at selling one-lot options strangles on the S&P 500 Index (SPX), initiated at 52 days-to-expiration (DTE).  The results in this post were derived from more than 2300 individual trades entered by the backtester.

For background on the setup for the backtests, as well as the nomenclature used in the charts and tables below, please see the introductory article for this series: Option Strangle Series - Higher Loss Thresholds

In the trade metrics tables, I have highlighted some of the metrics rows to indicate values that are in the upper half of the readings.  One of the metrics to note is the average P&L per day in percentage terms (Trade Details (%) - Avg. P&L / Day).  This is a measure of the P&L per day normalized to the maximum initial portfolio margin (initial PM) required for that trade run...it tells us the effectiveness of theta with respect to our margin requirement.

Also note, that all of the blog posts for the SPX strangle series have equity curves with identical y-axis scales.

With the 52 DTE tests, the highest average P&L per day readings occurred with the 4 delta short strike variations.  In the next post we will look at these same deltas and exits, but on the SPX 59 DTE short strangle.
