Why is Corporate Merch falling/rising?

As of 20-Jun, Corporate Merchant Bankers Ltd is experiencing a price increase, with its current price at Rs. 60.04, reflecting a rise of 1.17 or 1.99%. The stock has hit a new 52-week and all-time high today, and it has outperformed its sector by 0.42%. Over the past week, the stock has shown a return of +4.02%, and over the past month, it has increased by +21.76%. However, there are concerns regarding erratic trading, as the stock did not trade on 4 out of the last 20 days, and there has been a significant drop in delivery volume, which fell by -16.67% against the 5-day average. The stock is currently trading above all its moving averages, indicating a strong upward trend.
In the broader market context, the stock's performance has significantly outpaced the benchmark Sensex, which has only increased by +1.59% over the past week and +1.50% over the past month. Year-to-date, Corporate Merchant Bankers Ltd has achieved an impressive return of +261.03%, compared to the Sensex's +5.46%. This stark contrast highlights the stock's strong performance relative to the market. Despite the positive price movement, the declining investor participation and erratic trading patterns may raise concerns about the sustainability of this upward trend.
