Why is Zenotech Lab. falling/rising?

As of 30-Oct, Zenotech Laboratories Ltd is experiencing a price increase, currently priced at 53.00, reflecting a change of 0.6 or 1.15% upward. The stock has shown a strong performance recently, gaining 9.05% over the last seven days and outperforming its sector by 1.49% today. However, despite this positive momentum, the stock's year-to-date performance remains negative at -26.34%, and it has underperformed significantly over the past year with a decline of -34.57%. Additionally, the delivery volume has decreased by 2.86% compared to the five-day average, indicating a potential decline in investor participation, although the stock remains liquid enough for trading.
In the broader market context, Zenotech's recent short-term return of +6.62% over the past week contrasts sharply with the Sensex, which has seen a slight decline of -0.18% during the same period. This suggests that Zenotech is benefiting from specific factors that are driving its price up, even as the overall market is experiencing a downturn. However, the stock's longer-term performance remains concerning when compared to the benchmark, as it has underperformed the Sensex significantly over the past month, year, and three years.
