Traders can initiate a Moderately Bearish strategy with reduced premium outflow & lower breakeven point called Debit Put Spread or Bear Put Spread for 20th January Expiry wherein trader will buy one lot of 18,000 Put strike @ 83 and simultaneously sell one lot of 17,800 Put strike @ 15, so that net outflow or maximum loss will be restricted to up to Rs 3,400. If Nifty on expiry closes below 17,932 the strategy will start making profit, however, as there is one out of the money sold put which has helped to bring down the cost of Long Put and converted the strategy into limited risk & profits. The maximum gains will be restricted up to Rs 6,600 because the gains of long 18,000 strike Put will be offset by the sold 17,800 strike Put if Nifty closes below 17,800 on expiry.
