Despite a strong long-term performance, with a 131.32% return over the past year and consistent positive results for the last seven quarters, the stock's current valuation appears expensive, contributing to the recent price decline.
In the broader market context, the stock's short-term performance over the past week shows a decline of 5.25%, while the benchmark Sensex has only decreased by 0.18%. This underperformance highlights the stock's struggles in the current market environment, despite its impressive long-term growth metrics, such as a 57.33% increase year-to-date and a 504.27% rise over the past three years. The high institutional holdings at 25.01% indicate confidence from larger investors, but the recent volatility and declining delivery volumes may be causing concern among retail investors, leading to the stock's current downward trend.
