Shares of Billionbrains Garage Ventures, known as Groww, dropped sharply by over 9% on Thursday, extending previous day's losses. This follows a significant five-day post-listing rally that boosted the stock nearly 90% above its issue price. Investors are now keenly awaiting Groww's first quarterly results on Friday, November 21, 2025, which are seen as a crucial catalyst. The expiry of the one-month shareholder lock-in period on December 10, 2025, is also a key event to monitor.
