Why is Caplin Point Lab falling/rising?

As of 23-Sep, Caplin Point Laboratories Ltd is experiencing a decline in its stock price, currently at Rs 2,260.35, reflecting a decrease of Rs 57.7 or 2.49%. The stock has underperformed its sector by 2.14% today and has been on a consecutive downward trend for the last two days, with a total decline of 3.59% during this period. Despite having a higher performance over the past month (+4.16%) and year (+19.22%), the stock's year-to-date performance shows a significant drop of 9.65%. Additionally, the stock's delivery volume has decreased by 48.48% compared to the 5-day average, indicating falling investor participation, which may contribute to the recent price decline.
In the broader market context, while Caplin Point Laboratories has shown positive returns over the past week (+0.47%) compared to the Sensex's slight decline (-0.34%), its overall performance this year has lagged behind the benchmark index, which has gained 5.07%. The stock's high valuation, indicated by a Price to Book Value ratio of 6, may also be a concern for investors, especially given its recent profit growth of only 18.3% compared to a 19.22% return. Although institutional investors are increasing their stake, suggesting confidence in the company's fundamentals, the combination of high valuation and declining participation may be influencing the stock's current downward trajectory.
