Lyft seems to have a lot of shorting. People are heavily betting against it. They expect its price to drop. However, while it may be true that in the long term lyft will loose value, something weird can happen in the short term: Shorting requires borrowing shares. You pay a fee, borrow the share. If it looses value you make money. But if it gains value, and you are asked to return those shares back, you can loose a lot of money. Also, the act of asking for those shares back could raise the value, creating a negative feedback look. Disastrous for the short seller. Why might we see lots of shorts being asked to return the shares back? Due to the large amount of shorting and the bank wanting those shares for other purposes.
