Why is United Nilgiri falling/rising?

As of 24-Sep, United Nilgiri Tea Estates Company Ltd is experiencing a decline in its stock price, currently at 471.85, which reflects a decrease of 2.85 or 0.6%. The stock has underperformed its sector by 1.72% today, and its delivery volume has significantly dropped by 37.44% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has decreased by 4.67%, while it has shown a year-to-date decline of 13.49%. Despite a positive performance over the last year with a return of 13.69%, the stock's recent movements suggest a struggle against broader market trends, particularly as it has underperformed the Sensex, which has gained 5.97% year-to-date.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, with a 1-week decline of 4.67% compared to the Sensex's drop of only 1.08%. While the company has demonstrated strong financial results, including significant growth in profit before tax and profit after tax, the overall market sentiment appears to be affecting its stock price negatively. The stock is trading at a fair valuation with a low debt-to-equity ratio and has shown strong long-term performance, yet the recent underperformance and declining investor interest may be contributing to its current price drop.
