Why is V-Marc India falling/rising?

As of 02-Jul, V-Marc India Ltd is experiencing a price increase, with its current price at 377.65, reflecting a rise of 17.95 or 4.99%. The stock has shown strong performance today, outperforming its sector by 5.18%. Additionally, V-Marc India is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. Over the past week, the stock has surged by 25.72%, significantly outperforming the Sensex, which only increased by 0.83%. However, there is a notable decline in investor participation, with delivery volume dropping by 49.54% compared to the 5-day average, which could be a concern for future trading activity.
In the broader market context, V-Marc India's short-term performance has been exceptional compared to the benchmark, with a 1-week return of 25.72% against the Sensex's 0.83%. Despite a year-to-date decline of 1.49%, the stock has shown remarkable growth over the past year, with a return of 115.37%, far exceeding the Sensex's 5.51%. This strong historical performance, combined with today's positive price movement, suggests that while the stock is currently rising, the decrease in delivery volume may indicate potential volatility ahead.
