Why is Apollo Pipes falling/rising?

As of 04-Sep, Apollo Pipes Ltd is experiencing a decline in its stock price, currently at Rs 403.70, which reflects a decrease of Rs 5.1 or 1.25%. Today's price summary indicates that the stock underperformed its sector by 0.71%, with an intraday low of Rs 400.05, marking a drop of 2.14%. The stock has shown mixed performance over various periods, with a 1-week return of +4.29% but a significant year-to-date decline of -13.00%. Additionally, the company has a low Debt to EBITDA ratio of 1.31, indicating a strong ability to service debt, and institutional investors have increased their stake by 1.99%, suggesting a positive outlook from these investors. However, the stock's long-term growth prospects are poor, with operating profit declining at an annual rate of -22.50% over the last five years, and recent financial results have shown a significant drop in profit before tax and net sales.
Broader market context shows that while Apollo Pipes has underperformed the BSE500 over the last year and three years, it has managed to outperform the benchmark in the short term with a 1-week return that exceeds the Sensex's 0.80% gain. Despite this short-term outperformance, the stock's long-term performance remains concerning, with a return of -38.82% over the past year compared to the Sensex's modest decline of -1.98%. The combination of falling investor participation, as evidenced by a 45.45% drop in delivery volume, and the company's poor financial performance contributes to the negative sentiment surrounding the stock, leading to its current decline.
