Why is Apollo Pipes falling/rising?

As of 01-Sep, Apollo Pipes Ltd is experiencing a price increase, currently at 407.00, reflecting a rise of 3.0 (0.74%). The stock has shown a positive trend over the last two days, gaining 5.14% in this period, although it underperformed its sector by 0.92% today. In terms of returns, the stock has increased by 1.89% over the past week and 0.62% over the past month, while it has significantly lagged behind the benchmark Sensex, which has declined by 1.56% and 0.29% respectively. Despite a low Debt to EBITDA ratio indicating a strong ability to service debt, the stock faces challenges due to poor long-term growth, with operating profit declining at an annual rate of -22.50% over the last five years.
Broader market context shows that while Apollo Pipes has seen some short-term gains, it has underperformed the broader market over longer periods, with a year-to-date return of -12.28% compared to the Sensex's gain of 2.85%. The stock's long-term performance is concerning, as it has generated a return of -32.50% over the past year and has underperformed the BSE500 in multiple timeframes. The recent increase in institutional investor participation, which has risen by 1.99% in the last quarter, may provide some support, but the overall negative financial indicators and valuation concerns suggest a cautious outlook for the stock moving forward.
