Thanks. I've read the 50% ITM comment several times. So let's say the SP gets to $975 on 1/21. And I decide to roll. What new position would you roll into?
Well, ideally you roll BEFORE you're at fully 50% ITM... just the wider spread means you can go lower before you get to that.... AT 50% you're probably looking at adding 1 week for the same strike and about even on cost, hoping the stock goes up next week.
If you'd rolled before that (say "only" 25% into the spread width) you'd have a lot more options, and what you'd roll to would depend on your situation and what you think will happen... for example (these are made up #s just to give you an idea of the type of choices) you might be able to roll a 25% into the spread spread to:
1 week out, same strike, pocketing another net credit of X dollars (if you think stock will bounce back decently)
1 week out, a little lower strike, pocketing another net credit of Y dollars- Y being less than X. (if you think stock will bounce but not a ton)
1 week out, an even lower strike, but at even cost (if you think stock will mostly go sideways or maybe even down a bit more)
How much lower you can do the strikes or how much credit will depend on a slew of factors including how far into the spread it is, where IV is, how much time value is left on current spread, etc...
There might be other options you find appealing depending on what's going on, current IV, current or upcoming news, and what you think the stock will do...including potentially adding more time, though I personally try to stick to weekly for BPS when possible.
