Adjustment of F&O contracts of CAMS on account of Split

As per the circular, effective from December 05th, 2025 (ex-date), the CAMS F&O contracts will be revised based on the split adjustment factor.

Calculation of the adjustment factor: The adjustment factor for the stock split of A: B is defined as (A/B). In the case of CAMS, the adjustment factor is (5/1) = 5, since the split ratio is 5:1.

Adjustment for Futures Contracts:

Futures base price: The adjusted futures base price will be 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 750.

Example: If you are holding a position in CAMS NOV FUT, and on the pre-ex-date (December 04, 2025) the future closes at 3900, then on the ex-date the price will be adjusted to 780 (Price on pre-ex-date: 3900 / Adjustment Factor: 5). The lot size will be adjusted to 750 (Current lot size 150 × Adjustment Factor 5).

Adjustment for Options Contracts:

Strike Price: The adjusted strike price will be arrived at by dividing the old strike price by the adjustment factor.

Lot Size: The adjusted lot size will be arrived at by multiplying the old market lot by the adjustment factor. The revised lot size would be 750.

Example: If you are holding a position in CAMS NOV 4000 CE, the current lot size is 150.
On the ex-date, the 4000 CE will be adjusted to 800 CE (Strike Price: 4000 / Adjustment Factor: 5), and the lot size will be adjusted to 750 (Current lot size 150 × Adjustment Factor 5).

Also, if you hold equity shares of CAMS in your demat account as of December 05th, 2025 (ex-date), you will be entitled to receive the split shares, which will be credited to your demat account usually within two working days from the ex-date.
