Why is Tube Investments falling/rising?

As of 24-Sep, Tube Investments of India Ltd is experiencing a decline in its stock price, currently at 3,278.40, which represents a decrease of 24.3 points or 0.74%. The stock has underperformed its sector by 0.28% today and has been on a consecutive fall for the last two days, resulting in a total decline of 2.29% during this period. Over the past week, the stock has decreased by 3.23%, while it has shown a positive return of 6.75% over the last month. Despite its strong long-term fundamentals, including a low debt-to-equity ratio and significant growth in net sales and operating profit, the recent drop in delivery volume by 50.45% 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, Tube Investments' recent performance contrasts with the Sensex, which has only declined by 1.18% over the past week. The stock's year-to-date performance shows a decline of 7.75%, while the Sensex has gained 4.58% in the same timeframe. Although the company has high institutional holdings at 43.55%, suggesting confidence from larger investors, the overall market sentiment and the stock's recent underperformance relative to both its sector and the benchmark may be influencing its current price decline.
