Lending fee
Trading & ordersThe price of borrowing stock through SLB, quoted in rupees per share for the tenure and published daily by the exchange.
In plain terms
Divide it by the share price to get the cost as a percentage of the position, then weigh that against the move you expect. India publishes no short interest report, so a fee that has moved from a few paise to several rupees is the clearest public evidence that borrowing demand has risen.
