Stock options understanding

Suppose,

I sell infy call options, on expiry, if i don’t square of the position i have to give the delivery which means infy stocks will be debited from my demat account?
I buy infy call options, on expiry,if i don’t square of the position i have take the delivery which means infy stocks will be credited to my account?

I sell infy put options, on expiry,if i don’t square of the position i have take the delivery which means infy stocks will be credited to my account?
I buy infy put options, on expiry,if i don’t square of the position i have to give the delivery which means infy stocks will be debited from my account?

Is my understanding correct?

Yes, your understanding is correct. In all the above cases, physical settlement will happen only if the Options expire ITM, if Options are OTM, it will expire worthless and there won’t be any physical settlement. You can check out more information on physical settlement here.

So,

Lets say, I sell infy oct 1800 call option and 1600 put option.
Assuming oct monthly expiry . Infy is at spot 1700. Both my option are OTM . so i am not obligated to give delivery or take delivery after 28-10-2021 3:30 P.M. if i dont square up my position.

I can collect premium.

Right. If your options expire OTM, thise will expire worthless, there will be no physical settlement and as an option seller, you will get to keep the entire premium received.

My main concern is , Can i have the position as it is and not square up.
Because on monthly expiry spreads may become wider.

Yes, you can let your position expire. As explained above, if the position expires OTM, there will be no physical settlement and you will get go to keep the premium received.

Hi @ShubhS9

Lets say i have 100 infy shares in my holding.
I sell 1900ce infy (lot size is 300) for nov expiry.

If infy spot on nov expiry is 1950. instead of squaring the call options positions ,
Can i buy 200 infy stocks on expiry day and use the total 300(200+100) for delivery?

No…I don’t think that will do because you must have the whole lot in your demat…so you must buy 200 shares two days before expiry I believe…some expert can throw more light on this…

You need to have sufficient shares in your demat account on the day of expiry, else it will result in short delivery. Explained here.
