How do corporate actions influence a stock’s price? 

Corporate actions cause stock prices to adjust because they change the share structure, cash value, or business composition. These price movements are mechanical in nature and help realign the stock with its revised fundamentals. 

  • Bonus Issue/Stock Split: The number of shares increases, so the share price adjusts downward proportionately to distribute the same value across more shares.  

  • Dividend: The stock price typically declines on the ex-date to reflect the cash payout made to shareholders.  

  • Rights Issue: New shares issued at a discounted price may lead to a temporary price decline due to dilution. 

  • Buyback: A reduction in outstanding shares can support or increase the stock price by lowering market supply. 

  • Merger/Demerger/Spin-off: The stock price adjusts to reflect changes in business structure, ownership, and valuation.
