Stock split vs bonus issue — why did the price suddenly drop?
A split or bonus increases your share count and lowers the price proportionally — your total value is unchanged. A falling price here is mechanical, not a loss.
Sometimes a stock’s price drops sharply overnight with no bad news at all. Often the cause is a stock split or a bonus issue — corporate actions that increase the number of shares and reduce the price per share in proportion. Your total holding value does not change.
In a stock split, one share is divided into several (say, one ₹1,000 share becomes ten ₹100 shares). In a bonus issue, the company gives existing shareholders extra free shares from its reserves (a 1:1 bonus doubles your shares and halves the price). Either way, you own more shares at a lower price, and the maths nets to zero on day one.
Companies do this mainly to make the share price look more affordable and improve liquidity, which can attract more small investors. So if you see a stock "crash" 50% and the filings show a 1:1 bonus or 1:2 split, do not panic — check the corporate action before assuming something went wrong.
Example
You hold 10 shares at ₹2,000 (₹20,000 total). After a 1:1 bonus you hold 20 shares — but the price adjusts to ~₹1,000, so you still have ₹20,000. Nothing was lost; you simply have more shares.

Common questions
Do I make money from a bonus or split?
Not directly on the day — your total value is unchanged. The potential benefit is liquidity and, over time, the chance to gain if the now-cheaper, more-liquid stock attracts more buyers.
How do I know if a price drop was a split or real?
Check the company’s official filings/corporate actions (we decode these on each company page). A split or bonus will be announced with a record date; a real fall will have news behind it.
