Why is Peria Kara. Tea falling/rising?

As of 23-Jul, Peria Karamalai Tea & Produce Company Ltd's stock price is currently at 689.95, reflecting an increase of 4.95 (0.72%). Today's price summary indicates that the stock has outperformed its sector by 2.51%. However, despite this positive movement, the stock has shown a decline of 6.76% over the past week and 12.79% over the past month. While it has generated a substantial return of 70.65% over the last year, this is contrasted by poor financial performance, including a significant drop in profits by 95.5% and negative results in the latest quarter, which have raised concerns about its long-term growth potential. The stock's valuation appears expensive with a low return on equity of 2.8 and a price-to-book ratio of 1.1, despite trading at a discount compared to peers.
In the broader market context, the stock's recent performance has been notably weaker than the benchmark, with the Sensex showing a slight increase of 0.03% over the past week. The stock's year-to-date performance is also concerning, with a decline of 6.85% compared to the Sensex's gain of 6.66%. This divergence suggests that while the stock has had a strong historical performance, current market conditions and financial results are leading to a more cautious outlook among investors, contributing to its recent price movements.
