yeap, i have stress-tested and backtested this to death (since 2021)Indeed, as long as you can keep your puts out of assignment range they usually go OTM at some point, calls, not necessarily - I have a friend, used to post here sold -c135's against everything early 2023 and that was that, don't think he even got out of them in the last sub-140, problem is that you're always thinking "it's going to go lower", as indeed it should haven but didn't, then it reverses and the moment is gone
assuming no early assignment, 100% of rolled -p will eventually go OTM
-c is much more dangerous when ITM (higher chance of 'max' loss)
TSLA Rolling - does it work? Part 3
Compared to puts, calls take longer to OTM if rolled
if my 7DTE short call is breached, (for ex 2023-06-09 i have a 10% OTM bet -c235.36 but it closed at 244.39):
if one is selling 10% or 12% OTM calls, any breached call will take at most 6 rolls before it goes OTM (5-strike improvement every week, total $30 improvement) ie move -c200 into -c205 into -c210 into -c215 into -c220 into -c225 into -c230
- if i roll with no strike improvement (assuming no early assignment), i can close it in 10 weeks; this means rolling to the same strike 10 times
- if i roll with 5-strike improvement every week, it will go OTM in 3 weeks (week 1 -c240.36, week 2 -c245.36, week 3 -c250.36); this means rolling 3 times and going up total 15
- if i roll with 10-strike improvement every week, it will go OTM in 1 week (week 1 -p245.36); this means rolling 1 time and going up total 10
if one is selling 15% OTM calls, any breached call will take at most 2 rolls before it goes OTM (10-strike improvement every week, total $20 improvement) ie move -c200 into -c210 into -c220
if one is selling 8% OTM calls, there is a 15.82% chance that it will go ITM.
summary:
- rolled puts go OTM faster than rolled calls, especially if there is a 5- or 10- strike improvement every week
- assuming no early assignment, there is no "max loss" when rolling puts - 100% will eventually go OTM (since 2021)
- assuming no early assignment, "max loss" is possible when rolling calls
- "max loss" means you can roll up to today or for a long time, and it will still be ITM (might as well take the loss)
- translation: i should be more afraid of rolling calls than puts
