Bharat Petroleum goes ex-bonus in ratio 1:2 on 13th July. Please explain how it affects the average price and P&L of my holdings and F&O positions.
BPCL goes ex-bonus in the ratio 1:2 on 13 July 2017, i.e. 1 bonus share issued at Rs.0 for every two shares held in the Demat account of all eligible shareholders.
Effect on Holdings:
When a bonus is issued, the share price drops, in this case by a factor of (1+2)/2 = 1.5. So if you held BPCL shares at an average price of Rs.600, the price of each share after bonus would adjust to 600/1.5 = Rs.400. You’ll be given 1 share at Rs.0 for every two shares at Rs.400, thereby maintaining your overall investment value.
Please note that a bonus issue only increases liquidity and not your investment value.
Until the bonus shares are credited to your Demat, your Holdings will show an artificial drop in P&L of approximately 33%. Once the bonus shares are credited at an avg price of Rs.0, your P&L in Kite/Q will be restored to its correct value.
You will receive an SMS from CDSL when your bonus shares are credited to your Demat which could take upto 2 weeks.

Effect on F&O positions:
Option strike prices are divided by the factor of 1.5. A strike price of 720 becomes 480, 740 becomes 493.35 and so on. F&O lot sizes are multiplied by the factor of 1.5. The old lot size of 1200 will be revised to a new market lot of 1800.
The future and option prices are divided by the factor of 1.5 to maintain the same contract value as of before the bonus issue.
