Why is APL Apollo Tubes falling/rising?

As of 22-Jul, APL Apollo Tubes Ltd is experiencing a decline in its stock price, currently at Rs 1,660.30, which reflects a decrease of Rs 36.5 or 2.15%. The stock has underperformed its sector by 1.75% today, reaching an intraday low of Rs 1,654.05. Over the past week, the stock has decreased by 3.74%, and over the past month, it has fallen by 6.35%. Despite these short-term declines, the stock has shown strong long-term performance, with a year-to-date return of 5.42% and a one-year return of 11.96%. The company boasts solid fundamentals, including a high Return on Capital Employed (ROCE) of 26.81% and a low Debt to EBITDA ratio of 0.34 times, which indicates a strong ability to service debt. However, the recent drop in delivery volume by 41.2% against the 5-day average suggests a decrease in investor participation, which may be contributing to the stock's downward movement.
In the broader market context, APL Apollo Tubes' recent performance contrasts with the benchmark Sensex, which has only decreased by 0.47% over the past week. This indicates that the stock's decline is more pronounced than the overall market trend. While the company has high institutional holdings at 48.52%, suggesting confidence from larger investors, the recent price movement may reflect broader market sentiments or sector-specific challenges. Despite the stock's strong historical returns and positive growth indicators, the current market dynamics and reduced trading volume may be influencing investor sentiment negatively, leading to the observed decline in stock price.
