Why is Purple United falling/rising?

As of 17-Sep, Purple United Sales Ltd is experiencing a price increase, currently at 469.75, reflecting a rise of 19.75 or 4.39%. The stock has shown strong performance recently, with a one-month return of 39.83%, significantly outperforming the Sensex's 2.84% increase over the same period. Additionally, Purple United is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. However, there has been a notable decline in investor participation, with delivery volume dropping by 69.7% compared to the 5-day average, which may raise concerns about the sustainability of the stock's upward movement.
In the broader market context, while Purple United's one-week return of 0.91% is lower than the Sensex's 1.43%, its year-to-date performance of 144.98% far exceeds the Sensex's 7.13%. This substantial outperformance suggests that investor sentiment towards Purple United remains strong despite the recent drop in delivery volume. Overall, while the stock is currently rising, the significant decrease in trading volume could indicate potential volatility ahead, warranting close monitoring of future performance.
