Formula

New shares ≈ old × (1 + bonus%). Adjusted cost ≈ old cost ÷ (1 + bonus%). Theoretical ex ≈ price ÷ (1 + bonus%).

Classroom: 500 shares, 20% bonus, price 120

After 20% bonus you hold 600 shares. Theoretical ex-bonus is PKR 100. The real ex-print is a market number, not this worksheet.

Actual ex-price is a market print. This is classroom math.

FAQ

Is the result a buy or sell signal?

No. It is classroom arithmetic. Compare with filings and a licensed broker before any real order.

Is theoretical ex a target?

No. It is classroom math so bonus % is not mistaken for a free lunch.
