Why is Chandan Healthca falling/rising?

As of 17-Nov, Chandan Healthcare Ltd is experiencing a price increase, currently at 337.30, reflecting a rise of 23.9 or 7.63%. The stock has outperformed its sector by 5.21% today and is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating strong upward momentum. Over the past month, the stock has gained 15.12%, significantly outperforming the Sensex, which only rose by 1.18%. However, there has been a notable decline in investor participation, with delivery volume dropping by 54.05% compared to the 5-day average, which may raise concerns about the sustainability of the price increase.
In the broader market context, Chandan Healthcare's short-term performance of +1.60% over the past week is slightly below the Sensex's return of +1.72%. Despite this, the stock's strong performance over the past month and its current price movement suggest positive investor sentiment, although the falling delivery volume could indicate a potential slowdown in interest. Overall, while the stock is rising, the decrease in trading volume may warrant caution regarding future price stability.
