Why is Apollo Pipes falling/rising?

As of 26-Aug, Apollo Pipes Ltd is experiencing a decline in its stock price, currently at 398.65, which reflects a decrease of 0.8 or 0.2%. The stock has been underperforming recently, having fallen consecutively for the last four days, resulting in a total decline of 1.62% during this period. Although it outperformed its sector by 1.25% today, the stock's longer-term performance is concerning, with a year-to-date return of -14.08% and a one-year return of -30.51%. Additionally, the stock's delivery volume has decreased significantly, falling by 49.81% against the five-day average, indicating a drop in investor participation. While institutional investors have increased their stake by 1.99%, the overall sentiment remains negative due to poor long-term growth metrics, including a -22.50% annual rate of operating profit growth over the last five years.
In the broader market context, Apollo Pipes' recent performance contrasts with the benchmark Sensex, which has seen a slight increase of 3.39% year-to-date. The stock's short-term return of +0.91% over the past week is overshadowed by its longer-term underperformance, as it has lagged behind the BSE500 index over the last three years, one year, and three months. The company's financial health is also a concern, with a low return on capital employed (ROCE) of 5.93% and a high price-to-book value ratio of 2.3, indicating an expensive valuation relative to its peers. These factors contribute to a negative outlook for the stock, despite some positive signals from institutional investor participation.
