SEBI has prescribed a framework to the exchanges for adjustment of corporate actions in derivative contracts at the time of the corporate action. The exchange has published everything regarding the adjustments in the case of corporate actions here. The adjustments are carried out so that the value of the position of the market participants, on the cum and ex-dates for the corporate action, continues to remain the same as far as possible.
Here’s how the adjustment works:
The adjustment factor for the stock split of A: B is defined as (A/B). In the case of CANBK, the adjustment factor is (5/1) = 5, since the split ratio is 5:1.
Adjustment of 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 6750.
Example: If you are holding a position in CANBK MAY FUT and on pre-ex-date (May 14, 2024) futures close at 700, on ex-date the price will be adjusted to 140 (Price on pre-ex-date: 700 / Adjustment Factor: 5). While the lot size will be adjusted to 6750 (Current lot size: 1350 * Adjustment Factor: 5).
Adjustment of 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 6750.
Example: If you are holding a position in CANBK 650 CE, the current lot size is 1350. On ex-date, the 650 CE will be adjusted to 130 CE (Strike Price: 650 / Adjustment Factor: 5), and the lot size will be adjusted to 6750 (Current Lot Size: 1350 * Adjustment Factor: 5).
While those holding positions in F&O contracts are not eligible for corporate action benefits. If you are holding equity shares of CANBK on the record date (May 15, 2024), you will be eligible to receive the split shares.
The credit of shares can take up to 2 working days from the record date (May 15, 2024). You can check out more details here.
