Why is Peria Kara. Tea falling/rising?

As of 20-Jun, Peria Karamalai Tea & Produce Company Ltd's stock price is currently at 754.85, reflecting a decrease of 24.35, or 3.13%. The stock has underperformed its sector by 4.04% today, and it has shown a concerning trend with a delivery volume of 0 on June 19, indicating a 100% drop compared to the 5-day average. Although the stock has performed well over the past year with a return of 119.11%, significantly outpacing the market's 2.60%, its recent performance over the past week and month has been negative, with declines of 7.14% and 9.09%, respectively. The stock is currently trading above its 100-day and 200-day moving averages but below its 5-day, 20-day, and 50-day moving averages, suggesting mixed momentum.
In the broader market context, the stock's recent decline contrasts sharply with the Sensex, which has gained 1.59% over the past week and 1.74% over the past month. This underperformance may be attributed to falling investor participation and liquidity concerns, as evidenced by the significant drop in delivery volume. Despite the stock's impressive long-term returns over 3 years and 5 years, the recent negative trends in both short-term performance and investor engagement indicate that market sentiment may be shifting unfavorably for Peria Karamalai Tea & Produce Company Ltd.
