Adjustment of F&O contracts of BAJFINANCE on account of bonus and split
As per the circular, effective from June 16, 2025, the BAJFINANCE F&O contracts will be revised based on the bonus and split adjustment factor.
Calculation of the adjustment factor:
The adjustment factor for a bonus issue of A: B is defined as (A+B)/B. For Bajaj Finance Ltd, the adjustment factor is (4+1)/1 = 5, since the bonus issue ratio of 4:1.
The adjustment factor for the stock split of A: B is defined as (A/B). For Bajaj Finance Ltd, the adjustment factor is (2/1) = 2, since the split ratio is 2:1.
Therefore, the final adjustment factor for Split and Bonus in the security in the above ratios will be: 5 x 2 =10.
Adjustment for Futures Contracts:
Futures base price: The adjusted futures base price is arrived at by dividing the settlement price of the future one day before the ex-date by the adjustment factor.
Futures lot size: The adjusted market lot will be arrived at by multiplying the old market lot by the adjustment factor. The revised market lot would be 1250.
For example:
Assume you are holding a position in Bajaj Finance Ltd JUL FUT and on pre-ex-date (Jun 13, 2025) futures close at 9600, on ex-date the price will be adjusted to 960 (Price on pre-ex-date: 9600 / Adjustment Factor: 10)
While the lot size will be adjusted to 1250 (Current lot size: 125 * Adjustment Factor: 10).
Adjustment for Options Contracts:
Strike Price: The adjusted strike price is calculated by dividing the old strike price by the adjustment factor.
Lot Size: The adjusted lot size is arrived at by multiplying the old market lot by the adjustment factor. The revised lot size would be 1250.
For example:
Assume you hold a position in Bajaj Finance Ltd 9600 CE, the current lot size is 125. On ex-date, the 9600 CE will be adjusted to 960 (Strike Price 9600 / Adjustment Factor 10) and the lot size will be adjusted to 1250 (Current Lot Size: 125 * Adjustment Factor 10).
Also, if you hold equity shares of BAJFINANCE in your demat account as of June 16, 2025, you will be entitled to receive the bonus and split shares, which will be credited to your demat account usually within 2 days from the record date.
