Seems inherit the same limitation of RobinHood: you can't do short selling. Not sure how actually they could do a free commission order, so not sure why short selling is not supported, but it limits the use of long only strategy.

Interesting. I suppose it's a much more involved process where you need to locate shares to borrow. You need to maintain a list of easy to borrow and hard to borrow names. ETFs by definition are hard to borrow.

I used to work next to the stock loan desk at a bank. The equity markets are generally pretty tech driven these days but stock loan is still operating in a 1980s mentality.
