Most shorter's are just playing the current market for a short term gain when the price runs up, betting in the short term there will be profit taking.(unless the company is in financial trouble and they may hold be short longer). I believe ( not 100% positive) Aurora shares bought on margin are loanable by the broker since you are borrowing the money and do not need your approval. Cash accounts need you approval and they will pay you interest. Don't think there is a problem to find a loaner of ACB since there is appox. 1 billion share float.
Options have time limits, shorting against your long position does not. Just safer. Everything in the market is a risk. Just buying a long position is a risk. Some stocks have less risk than others, but still a risk.As you know there is no guarantee in the market.
