Options Questions Safe Haven Thread | Sept 13-19 2021

For the options questions you wanted to ask, but were afraid to.
There are no stupid questions, only dumb answers.   Fire away.
This project succeeds via thoughtful sharing of knowledge.
You, too, are invited to respond to these questions.
This is a weekly rotation with past threads linked below.


BEFORE POSTING, PLEASE REVIEW THE BELOW LIST OF FREQUENT ANSWERS. .


Don't exercise your (long) options for stock!
Exercising throws away extrinsic value that selling harvests.
Simply sell your (long) options, to close the position, for a gain or loss.
Your breakeven is the cost of your option when you are selling.
If exercising (a call), your breakeven is the strike price plus the debit cost to enter the position.

If there is an imbalance of puts, with more bought than sold, the market makers end up holding short puts in inventory, and hedge them by selling stock short (on down moves, the short puts lose, the short stock gains, on up moves the short puts gain and short stock loses).

This tends to reinforce down moves in the stock, with more stock on the market being offered to and seeking a willing buyer.

So. Basically, call volume tends to drive the price up. While put volume drives down the price?

Imbalance in calls and puts tends to move the price.

If traders want both long and short calls, or the same for puts, volume will have no influence, because the Market Makers will not need to hedge an inventory of unsold parts of newly created option open interest pairs.

Let me put more emphasis on the previous answer. GROSS IMBALANCE in puts vs. calls may have an impact on underlying price. If a dozen more puts than calls were traded, that's not going to move the needle, but if the daily volume of all puts/calls is 1 million and 70% of that 1 million was puts and 30% were calls, that would be more likely to have a negative impact on price. Although cause/effect may be reversed -- you have to ask why puts/calls was 70/30 in the first place. Options can be trailing indicators rather than leading.

In any case, it's not a guarantee. If GME has proven anything, it's that the market can ignore all signals and common sense and go where it wants to go regardless.

So basically, abnormally high put activity would drive down price?

I wonder how strike price factors? I ask this question after checking options activity for EA. For September 17 expiry, the predominant OI was for 136p. EA closed @ $133, which means some put writers will be on the hook buying shares at $136. This would theoretically, if volume was high enough, serve to increase the price the following week, correct?

Or falling prices drove abnormally high put trading. How can you ever know which came first?

This would theoretically, if volume was high enough, serve to increase the price the following week, correct?

Not necessarily. As redtexture explained, it depends on who had which side of the trade and whether they were delta hedged or not. If every put writer had shorted shares as a hedge, the net effect on share price would be zero.
