MobiKwik shares, after a 37% surge post-debut and reaching Rs 605, dipped 5.7% to Rs 510.30 on Friday due to profit-booking. The fintech firm's IPO, oversubscribed 119 times, fueled optimism about its profitability and the digital payments sector. Experts advise profit-booking given high listing gains, suggesting a stop-loss around Rs 400 for long-term holders.
