Why is Hi-Tech Pipes falling/rising?

As of 17-Sep, Hi-Tech Pipes Ltd is experiencing a price increase, currently at Rs 109.34, reflecting a rise of 2.1 (1.96%). The stock has shown strong performance recently, gaining 21.8% over the last seven days and outperforming its sector by 2.22% today. Additionally, the stock has outperformed the benchmark Sensex significantly over the past week and month, with returns of +19.96% and +25.20%, respectively. However, it is important to note that the stock has underperformed over the longer term, with a year-to-date decline of -31.49% and a one-year return of -43.73%. The company has reported healthy long-term growth, with net sales increasing at an annual rate of 23.58% and operating profit at 26.08%, contributing positively to its recent price movement.
In the broader market context, while the Sensex has only increased by 1.56% over the past week, Hi-Tech Pipes has significantly outperformed this benchmark, indicating strong investor interest in the short term. However, the stock's long-term performance remains concerning, as it has underperformed the market over the past year. The decrease in institutional investor participation, with a -7.58% reduction in their stake, raises questions about the stock's stability and future growth potential. Despite these challenges, the stock's attractive valuation and rising investor participation may be contributing factors to its recent price rise.
