Actually space....at bottoms, shorts cover. That means they are buying the shares they borrowed, when they went short.....higher. When the shorts cover, they then are on the long side of the trade and they return the shares they borrowed to the lender of those shares....and pocket the difference.
Stock xxx is considered high at 20.00. A short will sell any shares they have there, then short/borrow shares at that point. Ideally(for the short) the shorted stock goes down to $15. The short buys or covers the shares he borrowed(which returns the shares to the lender) and is ready to go long again. He pockets the difference.... 5 bucks in this case. He loses if the price goes up from $20. Not as risky for small stocks whose puts occur early in the month....but the payoff isn't all that either.
If the difference on the day is .003 short/borrow to cover/buy on 1.5M shares, you are looking at $4500 on the day.
If that is what happened, then price will go up as shorts are reloaded on the long side(which merely means the opposite of the short side) They have shares expecting price to go up. Some don't hold but for a few minutes or days. So when someone says they are long...they could immediately sell afterward saying they are long, and be truthful. And by the time you read what they posted they don't own shares.
Just a long way(and the lingo) of saying the shorts didn't sell to you today. They were buyers.
