Why is Diana Tea Co falling/rising?

As of 31-Jul, Diana Tea Company Ltd's stock price is currently at 33.07, reflecting an increase of 0.57 or 1.75%. The stock has shown a trend reversal, gaining after four consecutive days of decline. It has outperformed its sector by 1.67% today. However, despite this positive movement, the stock has a mixed performance over various periods, with a significant decline of 9.55% over the past week and a year-to-date drop of 14.10%. Positive financial indicators include a substantial growth in profit before tax and net sales, but the company faces challenges with weak long-term fundamental strength, as indicated by a -220.11% CAGR growth in operating profits over the last five years.
In the broader market context, the Sensex has declined by 1.22% over the past week, which suggests that the stock's recent rise is somewhat insulated from broader market trends. While the stock's short-term performance is better than the benchmark, it still reflects a significant underperformance over the longer term, with a year-to-date decline compared to the Sensex's 3.90% increase. The stock's liquidity remains adequate for trading, but falling investor participation, as evidenced by an 82.63% drop in delivery volume, raises concerns about sustained interest in the stock.
