A stock trades at ₹500 in the spot market. The one-month futures on it trades at ₹506. A trader sells the futures and buys the stock at spot, holding until expiry (ignoring costs and dividends). What is the gain locked in at expiry per share?

The locked-in gain is ₹6 per share. The trader buys at ₹500 in spot and sells futures at ₹506; at expiry, futures converge to spot, so the position is effectively sold at ₹506. This cash-and-carry arbitrage profit equals the ₹6 difference.

Explanation

Buy spot at 500 and sell futures at 506. At expiry the futures price converges to spot, so the futures sale and the stock position together deliver 506 for a stock bought at 500. The locked-in gain is 506 - 500 = ₹6. Option ₹12 doubles the basis; ₹0 would apply only if futures equalled spot.
