Question: What happens to those shorted shares if the owner wants to sell their share, does the shorter have to buy them back before they can sell.
Can you tell your institution that you dont want your shares leant out for shorting.
I have VOC and have bought them thru comsec. can Comsec lend my shares out and if they can can I instruct comsec not to do that. Does not make sense to me that an individual would like to see their share price go down. Sorry in advance if these questions are too much work It's hard to find exactly what happens with shorted shares.
