Why is Corporate Merch falling/rising?

As of 29-Sep, Corporate Merchant Bankers Ltd is experiencing a price increase, currently at Rs. 191.95, which reflects a rise of Rs. 3.75 or 1.99%. The stock has been on a positive trajectory, gaining for the last 21 days and achieving a remarkable 50.98% return over this period. It has also reached a new 52-week and all-time high today. The stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating strong upward momentum. However, there has been a notable decline in investor participation, with delivery volume dropping by 95.54% against the 5-day average, which could suggest a potential concern for future sustainability of this price movement.
In the broader market context, Corporate Merchant Bankers Ltd has significantly outperformed the benchmark Sensex, which has seen a decline of 2.18% over the past week while the stock itself has surged by 10.32%. This stark contrast highlights the stock's strong performance relative to the market. Additionally, the stock's year-to-date return of 1054.24% far exceeds the Sensex's 2.85%, further emphasizing its exceptional growth. While the stock's liquidity appears sufficient for trading, the falling investor participation may pose a risk to its continued rise if not addressed.
