So im curious. I did see this. When does the securities have to be bought? What was the reason they were sold? I never dug deep into it. Im smooth i just buy and hold.

It’s how short selling works. They borrow a security for a fee and sell it at its current price, then repurchase the security later and return it to the lender. If the price has gone down, they profit the difference 

It’s been a standard financial practice for centuries
