Why is Apollo Pipes falling/rising?

As of 12-Sep, Apollo Pipes Ltd is experiencing a decline in its stock price, currently at Rs 390.00, which reflects a decrease of Rs 8.6 or 2.16%. The stock has underperformed its sector by 3.7% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 2.48%. Additionally, the stock has shown poor performance over various time frames, with a year-to-date return of -15.95% and a one-year return of -38.41%. The company's financial health is also concerning, as it has reported a low return on equity (ROE) of 4.1 and a significant decline in operating profit over the past five years, which has contributed to its expensive valuation relative to its peers.
In the broader market context, the Sensex has increased by 1.48% over the past week, contrasting sharply with Apollo Pipes' decline of 2.86% during the same period. While there has been an increase in institutional investor participation, with a 1.99% rise in their stake, the overall sentiment towards the stock remains negative due to its poor long-term growth prospects and disappointing recent financial results. The stock's performance has been below par not only in the short term but also in the long term, as evidenced by its underperformance against the BSE500 over the last three years, one year, and three months.
