In this post we’ll take a look at the backtest results of opening one DIS short put 0 DTE cash-secured position each trading day from Jan 3 2007 through Dec 27 2019 and see if there are any discernible trends. We’ll also explore the profitable strategies to see if any outperform buy-and-hold DIS.
There are 10 backtests in this study evaluating over 9,400 DIS short put 0 DTE cash-secured trades.
Let’s dive in!
Systematically opening DIS short put 0 DTE cash-secured positions was profitable for 6 out of 10 strategies.
None of the DIS short put 0 DTE cash-secured strategies outperformed buy-and-hold DIS with regard to total return.

Managing trades early outperformed holding till expiration with regard to win rate. 5D is an exception due to commission drag.
The higher the delta the lower the win rate.
Worst Monthly Return
Average P/L Per Day
Average Trade Duration
Managing trades at 50% max profit improved the efficiency of capital and shortened the average trade duration.
Time in Market
Not depicted in the chart and table above, the majority of the time spent out of the market was between January 3 2007 through September 30 2013.
Compound Annual Growth Rate
Profit Spent on Commission
18.6% – the blended average percent of profits spent on commission across profitable strategies.
Early management underperformed holding till expiration with regard to total P/L. 50D was an exception.
The higher the delta the higher the total P/L. 10D was an exception.
Six out of 10 option strategies were profitable.
The combination of order-entry mechanics and available CBOE options products (only monthlies existed for several of the early years of the backtest duration) caused the strategy to experience:
- ~42% of time in the market
- material amounts of timing luck
As highlighted in the methodology section, the “ultra short” 0 DTE strategy calls for options with 0-3 DTE horizons. 0 DTE would equate to a position opened and expiring same day whereas a 3 DTE position would equate to a position opened on Friday and closed on a Monday (Fri = 0 DTE, Sat = 1, Sun = 2, Mon = 3).
DIS, unlike SPY, does not have Monday-expiring or Wednesday-expiring options. Therefore, positions are opened Tues (3 DTE), Wed (2 DTE), Thurs (1 DTE) and Fri (0 DTE) so long as a delta exists in the respective range.
