If you enter into a short sale at time 0 and cover at time T, you get paid interest on your collateral or margin requirement by the lender of the asset. This is called the short rebate or (in the bond market) the repo rate. As the short seller, you’ll be required to pay the time T asset price along with lease rate, which is based on the dividends or bond coupons the asset pays out from 0 to T.
So, if no dividends/coupons are paid out, it’s theoretically possible for you to profit from selling short despite no change in the underlying asset price.
