How is it free when I pay £9.99 a month?
There is a risk that if there is a short squeeze you lose your shares. For example. I own stock in a battered medtech company. This company has a very unhealthy share price but is having a lot of success and would be a buyout target. Any buyout offer could be at high multiple of the SP. No guarantee that’s the short could cover that and I get my stock back
