Why is HVAX Technolog. falling/rising?

As of 22-Sep, HVAX Technologies Ltd is experiencing a price increase, with its current price at 852.50, reflecting a rise of 77.5 points or 10.0%. The stock has outperformed its sector today by 10.5%, and its performance over the past week shows a gain of 9.22%. However, it has seen a decline of 0.58% over the past month. The stock is currently trading above its 5-day, 20-day, 100-day, and 200-day moving averages, although it is below its 50-day moving average. Notably, there has been a significant drop in investor participation, with delivery volume on 19 September falling by 77.78% compared to the 5-day average, which may indicate reduced interest among investors.
In the broader market context, HVAX Technologies Ltd's short-term performance has been strong compared to the benchmark Sensex, which has only increased by 0.53% over the past week. Year-to-date, HVAX has outperformed the Sensex significantly, with a return of 31.94% compared to the benchmark's 6.59%. This suggests that while the stock is currently rising, the decline in delivery volume may raise concerns about sustainability. Overall, the stock's recent upward movement can be attributed to its strong short-term performance and sector outperformance, despite the noted decrease in investor participation.
