Why is Peria Kara. Tea falling/rising?

As of 16-Jul, Peria Karamalai Tea & Produce Company Ltd is experiencing a decline in its stock price, currently at 740.00, which reflects a decrease of 5.45 (-0.73%). The stock has underperformed its sector by 0.65% today and is trading higher than its 200-day moving average but lower than its 5-day, 20-day, 50-day, and 100-day moving averages. Over the past week, the stock has seen a return of -5.60%, contrasting sharply with its impressive 1-year return of 78.90%. However, despite this strong yearly performance, the company's profits have significantly decreased by 95.5%, raising concerns about its long-term growth potential, especially given the poor net sales growth rate of 5.13% over the last five years.
In the broader market context, the stock's recent performance has been notably weaker compared to the benchmark, with the Sensex showing a decline of only 1.04% over the past week. This underperformance is further highlighted by the company's negative results reported for March, including a substantial drop in profit before tax and a low cash position. While the stock has generated impressive returns over the past year, the significant decline in profitability and the high valuation metrics, such as a Price to Book Value of 1.2, suggest that investors may be reassessing the stock's value in light of its financial challenges.
