2. Why the Bonus Issue? – Fundamental Analysis

3. What’s the Impact on Stock Price? – Analysis
In the short term, the bonus issue is likely to act as a positive catalyst for the stock price. The increase in the number of outstanding shares and the resulting decrease in price per share can stimulate investor buying interest. However, the potential for short-term volatility should also be considered. In the long term, while there’s no direct impact on the company’s intrinsic value, the increased liquidity and the effort to enhance shareholder value can be interpreted as positive signals.
- Short-term impact: Potential for stock price increase, increased short-term volatility, possible improvement in trading volume.
- Long-term impact: No change in intrinsic value, minimal concern about dilution of shareholder value, potential for positive interpretation.
4. What Should Investors Do? – Investment Strategy
Short-term investors can consider capitalizing on the potential stock price increase driven by expectations surrounding the bonus issue, but should be mindful of price volatility around the listing date. Long-term investors should focus on the company’s fundamentals and growth prospects when making investment decisions.
- Short-term investment: Consider buying (beware of volatility).
- Long-term investment: Maintain a positive outlook (focus on fundamentals and growth potential).
