Why is Senores Pharma. falling/rising?

As of 16-Oct, Senores Pharmaceuticals Ltd is experiencing a price increase, currently at 739.15, reflecting a rise of 19.85 or 2.76%. The stock has recently hit a new 52-week and all-time high of Rs. 755.1, indicating strong upward momentum. Over the past week, the stock has gained 2.74%, and over the last month, it has risen by 8.02%. Additionally, the company has demonstrated impressive financial performance, with net sales growing at an annual rate of 85.60% and operating profit increasing at 130.72%. However, there has been a notable decline in investor participation, with delivery volume dropping by 45.65% compared to the 5-day average, which may raise concerns about sustainability.
In the broader market context, Senores Pharmaceuticals has outperformed the Sensex, which has increased by 1.58% over the past week and 1.32% over the past month. The stock's year-to-date return of 29.93% significantly surpasses the Sensex's 6.82% during the same period. Despite the positive growth indicators, the stock's high valuation, reflected in a Price to Book Value of 4.3 and a return on equity of 7.4, suggests that it may be considered expensive. This valuation concern, combined with the recent drop in trading volume, could impact investor sentiment moving forward.
