Pidilite Industries (₹3,048.30) has announced a bonus with a ratio of 1:1. So, the adjustment factor will be 2. The bonus issue will lead to necessary adjustments in the futures and options (F&O) contracts on this stock on the record date.
The company has decided September 23 as the record/effective date. On this day, the stock price and all derivatives contracts on Pidilite Industries will be adjusted appropriately.
