Adjustment of F&O contracts of PATANJALI on account of bonus.
As per the circular, effective from September 11, 2025, the PATANJALI F&O contracts will be revised based on the bonus adjustment factor.
Calculation of the adjustment factor:
The adjustment factor for a bonus issue of A: B is defined as (A+B)/B. For PATANJALI, the adjustment factor is (2+1)/1 = 3 since the bonus issue ratio of 2:1.
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 900.
For example:
Assume you are holding a position in PATANJALI SEP FUT and on pre-ex-date (Sep 10, 2025), futures close at 1830, on ex-date, the price will be adjusted to 610 (Price on pre-ex-date: 1825 / Adjustment Factor: 3)
While the lot size will be adjusted to 900 (Current lot size: 300 * Adjustment Factor: 3).
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 900.
For example:
Assume you hold a position in PATANJALI 1800 CE. The current lot size is 300. On ex-date, the 1800 CE will be adjusted to 600 (Strike Price 1800 / Adjustment Factor 3), and the lot size will be adjusted to 900 (Current Lot Size: 300 * Adjustment Factor 3).
