Why is Caplin Point Lab falling/rising?

As of 22-Sep, Caplin Point Laboratories Ltd is experiencing a decline in its stock price, currently at 2,310.00, reflecting a decrease of 34.6 points or 1.48%. Despite this drop, the stock has shown positive performance over the past week and month, with returns of 1.47% and 6.45%, respectively. However, it underperformed its sector by 0.4% today, and there has been a notable decrease in investor participation, with delivery volume falling by 34.96% compared to the 5-day average. The stock remains above its moving averages across various time frames, indicating some underlying strength. While the company has demonstrated high management efficiency and consistent positive results over the last 12 quarters, its valuation appears expensive relative to peers, which may be contributing to the current price decline.
In the broader market context, Caplin Point Laboratories has outperformed the Sensex over the past week and month, but it has underperformed year-to-date, with a return of -7.66% compared to the Sensex's gain of 5.15%. The recent increase in institutional investor participation, with a 0.65% rise in stake, suggests confidence in the company's fundamentals, yet the high Price to Book Value ratio and the relatively high PEG ratio indicate that the stock may be overvalued. This combination of strong historical performance and current valuation concerns may be influencing investor sentiment, leading to the observed price decline.
