Understand the impact of bonus share issues on your investment. When a company issues bonus shares, the stock price is adjusted downwards in proportion to the bonus ratio. This tool helps you calculate the theoretical ex-bonus price and demonstrates the concept of 'Wealth Neutrality'—showing that while the number of shares you own increases, the total value of your investment remains theoretically the same immediately after the adjustment.
