Bonus changes the share ledger
It increases units by ratio, but the economic value still needs a dated price reference to become a rupee answer.

Bonus vs Split vs Dividend in India: What Actually Changes for Investors?
A practical guide to the three most-confused corporate actions in Indian equities: what each event changes, what it does not, and how to audit the result properly.
Direct answer
A bonus changes units held, a split changes denomination and share count, and a dividend creates cash per share. None of them should be treated as the same thing, and none should be presented as free return without a dated ledger.
Why this query matters
Many investors know these terms in isolation but still get confused when a long-term return claim combines them. That confusion is exactly where bad spreadsheets, misleading posts, and inflated return claims are born.
Split is not the same as bonus
Both may increase share count, but split changes denomination mechanics while bonus is a separate corporate-action event.
Dividend belongs in cash
Unless reinvestment is modeled explicitly, dividend should remain in the payout ledger rather than being hidden in a rewritten chart.
Method
How to verify this claim without relying on hype.
- Step 1
Map every corporate action to its effective trading-date treatment.
- Step 2
Update shares for bonus and split separately rather than merging them into one adjustment bucket.
- Step 3
Record dividend as cash payout with per-share logic.
- Step 4
Recompute the portfolio value only after the share and cash ledgers are both updated.

FAQ
Questions investors usually ask next.
Do bonus and split mean the same thing?
No. Both can increase share count, but they come from different mechanics and should remain separate in any serious return analysis.
Why should dividends stay separate from the price chart?
Because the raw chart should stay raw. Dividend is a cashflow event, so mixing it directly into the price line makes the return decomposition harder to audit.
Can corporate actions happen on non-trading days?
Yes, which is why serious tools need an explicit rule for how non-trading-day events map onto the next relevant trading date.
