How does a 1:2 Bonus Issue affect my holdings?

A 1:2 bonus issue gives you one free share for every two you own, increasing your share count but decreasing the price per share proportionally, so the total value of your investment stays the same initially, rewarding you by boosting your holdings for future growth. For example, 100 shares at ₹100 become 150 shares at around ₹66.67 each, keeping the total investment value at ₹10,000.
