When an investor makes money on a short, who loses the money?
The correct answer to this question is:  the person who the short sells the stock to. Here's why this is the case.  Say we have A, who owns the stock and lends it to B, who then sells it short to C. After this the price drops and B buys the stock back from D and returns it to A. The outcome for A is neutral.  Typically stock that is sold short must be held in a margin account; the broker can borrow the shares from A, collect interest from B, and A has no idea this is going on, because the shares are held in a street name (the brokerage's name) and not A. If A decides during this period to sell, the transaction will occur immediately, and the brokerage must shuffle things around so the shares can be delivered.  If this is going to be difficult then the cost for borrowing shares becomes very high. The outcome for B is obviously a profit: they sold high first and bought (back) low afterwards. This leaves either C or D as having lost this money.  Why isn't it D? One way of looking at this is that the profit to B comes from the difference in the price from selling to C and buying from D.  D is sitting on the low end, and thus is not paying out the profit.  D bought low, compared to C and this did not lose any money, so C is the only remaining choice. Another way of looking at it is that C actually "lost" all the money when purchasing the stock.  After all, all the money went directly from C to B.  In return, C got some stock with the hope that in the future C could sell it for more than was paid for it.  But C literally gave the money to B, so how could anybody else "pay" the loss? Another way of looking at it is that C buys a stock which then decreases in value.  C is thus now sitting on a loss.  The fact that it is currently only a paper loss makes this less obvious; if the stock were to recover to the price C bought at, one might conclude that C did not lose the money to B.  However, in this same scenario, D also makes money that C could have made had C bought at D's price, proving that C really did lose the money to B. The final way of seeing that the answer is C is to consider what happens when somebody sells a stock which they already hold but the price goes up; who did they lose out on the gain to?  The person again is; who bought their stock.  The person would buys the stock is always the person who the gain goes to when the price appreciates, or the loss comes out of if the price falls.
