Why is Apollo Pipes falling/rising?

As of 05-Sep, Apollo Pipes Ltd is experiencing a decline in its stock price, currently at Rs 401.50, which reflects a decrease of Rs 2.2 or 0.54%. The stock has underperformed its sector by 0.71% today and has been on a consecutive downward trend for the last two days, resulting in a total drop of 1.79%. Over the past week, the stock has decreased by 0.62%, and it has shown a significant decline of 38.23% over the past year. Despite a low Debt to EBITDA ratio indicating a strong ability to service debt, the company has faced poor long-term growth, with operating profit declining at an annual rate of 22.50% over the last five years. Additionally, negative financial results reported in June, including a 38.9% fall in profit before tax, have contributed to the stock's recent struggles.
In the broader market context, the Sensex has increased by 1.13% over the past week, contrasting sharply with Apollo Pipes' negative performance. While institutional investors have increased their stake in the company by 1.99%, indicating some level of confidence, the overall sentiment remains cautious due to the stock's underperformance against the BSE500 over various time frames. The stock's liquidity is adequate for trading, but the significant drop in delivery volume suggests waning investor interest, further exacerbating its price decline.
