Two recent IPOs, Billionbrains Garage Ventures (Groww) and Pine Labs, have shown contrasting post-listing performances. Groww experienced massive initial gains driven by FOMO and a short-squeeze, followed by a sharp correction ahead of its Q2 results, facing regulatory and competitive headwinds. Pine Labs is struggling due to market saturation and intense competition from larger players like Paytm, despite its early mover advantage and a more palatable valuation.
