Why is HLE Glascoat falling/rising?

As of 12-Sep, HLE Glascoat Ltd is experiencing a decline in its stock price, currently at Rs 521.45, which reflects a decrease of Rs 14.0 or 2.61%. The stock has underperformed its sector today by 3.48% and has been on a downward trend for the last four days, accumulating a total loss of 9.29% during this period. The stock touched an intraday low of Rs 516.45 and has seen a decrease in delivery volume, which fell by 13.39% compared to the five-day average. Despite a strong year-to-date return of 41.20% and a one-year return of 28.53%, the stock's performance over the last three years has been poor, with a decline of 32.51%. While the company has shown high management efficiency and positive quarterly results, concerns about long-term growth and an expensive valuation relative to its peers may be contributing to the recent price drop.
In the broader market context, the Sensex has gained 1.48% over the past week, contrasting sharply with HLE Glascoat's decline of 5.19% during the same period. This underperformance against the benchmark indicates that investor sentiment may be shifting away from the stock, despite its historical outperformance in the past year. The overall market has generated negative returns of -3.45% in the last year, yet HLE Glascoat has managed to deliver positive returns, which suggests that while the company has potential, current market dynamics and investor participation are weighing heavily on its stock price.
