Why is United Nilgiri falling/rising?

As of 23-Jul, United Nilgiri Tea Estates Company Ltd is experiencing a decline in its stock price, currently at 470.40, which represents a decrease of 8.35 or 1.74%. The stock's performance today is in line with its sector, although it is trading higher than its 20-day, 50-day, 100-day, and 200-day moving averages, but lower than its 5-day moving average. Notably, there has been a significant drop in investor participation, with delivery volume falling by 38.71% against the 5-day average. Over the past week, the stock has decreased by 2.72%, while it has shown a positive return of 11.17% over the past month. Despite a year-on-year return of 12.75%, the stock has underperformed year-to-date with a decline of 13.75%, indicating some volatility in its recent performance.
In the broader market context, the stock's short-term performance has lagged behind the benchmark, with the Sensex showing a slight increase of 0.03% over the past week. The company's low debt-to-equity ratio and fair valuation, indicated by a Price to Book Value of 1.1 and a PEG ratio of 0.8, suggest a stable financial position. However, the falling investor participation and the stock's underperformance year-to-date may be contributing to the current price decline. Despite generating a return of 12.75% over the last year, which is significantly higher than the market average, the recent trends indicate challenges that may be impacting investor sentiment.
