Why is APL Apollo Tubes falling/rising?

As of 17-Jul, APL Apollo Tubes Ltd is currently priced at 1,690.00, reflecting a decrease of 19.2 points or 1.12%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total decline of 2.02% during this period. Additionally, the stock's performance over the past week shows a decline of 1.54%, while it has underperformed the sector by 1.59% today. Despite these short-term challenges, the company demonstrates strong long-term fundamentals with a robust average Return on Capital Employed (ROCE) of 26.81% and significant growth in net sales and operating profit. However, the recent drop in delivery volume by 37.82% against the 5-day average indicates a decrease in investor participation, which may be contributing to the stock's downward movement.
In the broader market context, the Sensex has also experienced a decline of 1.12% over the past week, suggesting that the stock's short-term performance is in line with the overall market trend. While APL Apollo Tubes has shown impressive long-term returns, including a 7.30% increase year-to-date and an 8.88% rise over the past year, the recent performance contrasts sharply with the benchmark's positive return of 0.83% over the last month. This divergence highlights the stock's current struggles despite its strong fundamentals and high institutional holdings, which could provide some support in the long run.
