Not sure if this is the right forum for this, but just a couple of questions: I'm interested to know under what circumstances a 'forced buy in/buy to cover' situation typically occurs when one holds a short stock position. 1) Ie, do such buy-in demands usually occur during advances in stock price (potentially leading to the dreaded 'short squeeze'), or can you get hit with a demand to cover your position at any time, even when price is declining? 2) If anyone cares to comment, how in general how common is it to get hit with forced buy-ins? Is it that 'it hardly ever happens unless the share price increases a lot', or is it 'happens all the time, pal, totally at random', or is the frequency somewhere in between? ==== I'm mainly curious because I'd like to write some covered puts (on highly liquid, large-cap equities, btw), and am just trying to get some idea of how likely it is that I'd find the underlying short closed, leaving me with a naked put! Thanks for any input you may wish to offer!
