Why is Hester Bios falling/rising?

As of 07-Aug, Hester Biosciences Ltd is experiencing a price increase, currently at Rs 2,014.70, reflecting a rise of Rs 26.55 or 1.34%. The stock has shown a positive trend today, outperforming its sector by 0.69% and marking a trend reversal after three consecutive days of decline. It reached an intraday high of Rs 2,065.2, which is a 3.88% increase. However, the stock's delivery volume has decreased significantly, falling by 37.05% compared to the five-day average, indicating a decline in investor participation. Over the past week, the stock has gained 3.85%, while its performance over the last month shows a notable increase of 12.99%. Despite this, the stock has underperformed on a year-to-date basis, down 15.80%, and over the past year, it has decreased by 23.77%.
In the broader market context, Hester Biosciences' recent performance contrasts sharply with the Sensex, which has declined by 0.69% over the past week and 3.38% over the past month. While the stock has shown resilience in the short term, its year-to-date performance remains negative compared to the benchmark's positive return of 3.18%. This divergence suggests that while Hester Biosciences is currently rebounding, it has faced significant challenges over a longer time frame, as evidenced by its declines over the past year and three years, where it has underperformed relative to the Sensex.
