Why is Amerise BioScie falling/rising?

As of 28-Oct, Amerise Biosciences Ltd is experiencing a price increase, currently at 0.66, with a change of 0.01 or 1.54% up. The stock has shown strong performance recently, gaining 20% over the past week and outperforming its sector by 1.8% today. However, despite this recent uptick, the stock's year-to-date performance remains significantly negative at -45.45%. Additionally, while the stock is currently above its 5-day and 20-day moving averages, it is still below its longer-term moving averages, indicating mixed momentum. Notably, there has been a decline in investor participation, with delivery volume dropping by 29.68% compared to the 5-day average, which may raise concerns about the sustainability of the recent gains.
In the broader market context, Amerise Biosciences' short-term performance of +20.00% over the past week contrasts sharply with the Sensex, which has only increased by 0.24% in the same period. However, over the longer term, the stock has underperformed the benchmark, with a year-to-date decline of -45.45% compared to the Sensex's gain of 8.30%. This disparity highlights the challenges faced by Amerise Biosciences in maintaining investor confidence and market traction, despite its recent positive price movement.
