Why is Senores Pharma. falling/rising?

As of 24-Sep, Senores Pharmaceuticals Ltd is currently priced at Rs 709.00, reflecting a decrease of Rs 8.85 or 1.23%. Today, the stock has underperformed its sector by 0.78%, having touched an intraday low of Rs 699.2, which represents a decline of 2.6%.

Despite this recent dip, the company has demonstrated strong long-term growth, with net sales increasing at an annual rate of 85.60% and operating profit growing at 130.72%. However, the stock's valuation appears expensive with a Price to Book Value of 4.2, and there has been a slight decrease in institutional investor participation, which may be contributing to the stock's current downward pressure.
In the broader market context, the Sensex has experienced a decline of 1.18% over the past week, indicating that while Senores Pharmaceuticals has outperformed the benchmark in this timeframe, it has not maintained this momentum today. The stock's year-to-date performance remains strong at 24.63%, compared to the Sensex's 4.58%, suggesting that the company has been resilient in a challenging market. However, the recent underperformance today and the decline in institutional investor stakes may signal caution among investors, impacting overall sentiment towards the stock.
