Why is Corporate Merch falling/rising?

As of 24-Sep, Corporate Merchant Bankers Ltd is experiencing a price increase, currently at Rs. 180.95, which reflects a rise of Rs. 3.5 or 1.97%. The stock has been on a positive trajectory, gaining for the last 21 days and achieving a remarkable 51.02% return during this period. Additionally, it has 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 significant decline in investor participation, with delivery volume dropping by 95.41% against the 5-day average, which may raise concerns about sustainability in the stock's upward movement.
In the broader market context, Corporate Merchant Bankers Ltd has significantly outperformed the Sensex, with a 1-week return of +10.30% compared to the benchmark's -1.18%. Over the past month, the stock has surged by 54.03%, while the Sensex has only increased by 0.50%. Year-to-date, the stock's performance is exceptional at +988.09%, contrasting sharply with the Sensex's modest gain of 4.58%. This stark difference in performance highlights the stock's strong appeal in the current market environment, despite the noted decline in delivery volume, which could suggest a potential risk if it continues.
