Why is HLE Glascoat falling/rising?

As of 25-Aug, HLE Glascoat Ltd's stock price is rising, currently at Rs. 542.20, reflecting an increase of Rs. 21.6 or 4.15%. The stock has recently hit a new 52-week high of Rs. 552.9 and has outperformed its sector by 3.04%. Over the past week, it has gained 29.82%, and in the last month, it has risen by 26.24%. Despite a recent drop in delivery volume by 49.7%, the stock is trading above its moving averages, indicating strong momentum. The company's high management efficiency, demonstrated by a return on capital employed (ROCE) of 21.26%, and significant growth in profit before tax and profit after tax in the latest quarter contribute positively to its recent performance.
In the broader market context, HLE Glascoat's impressive short-term returns stand in stark contrast to the benchmark Sensex, which has only increased by 0.45% over the past week and 0.21% over the past month. While the stock has shown resilience and market-beating performance, generating a 28.79% return over the past year compared to the BSE500's negative returns, concerns about long-term growth persist due to a modest annual operating profit growth rate of 13.07% over the last five years. Additionally, the stock's valuation appears expensive relative to its peers, despite its strong recent performance, which may temper investor enthusiasm moving forward.
