Why is V-Marc India falling/rising?

As of 08-Sep, V-Marc India Ltd's stock price is currently at 443.20, reflecting a decrease of 21.85 points or 4.7%. The stock has underperformed its sector by 4.89% today, and there has been a notable decline in investor participation, with delivery volume dropping by 73.2% compared to the 5-day average. Although the stock is trading higher than its 50-day, 100-day, and 200-day moving averages, it is lower than its 5-day and 20-day moving averages. Over the past week, the stock has decreased by 5.14%, while it has shown a positive return of 1.87% over the past month and a significant increase of 15.61% year-to-date.
In the broader market context, the Sensex has increased by 0.60% over the past week, indicating that V-Marc India’s decline is not reflective of the overall market trend. While the stock has performed well over longer periods, such as a 1097.84% increase over the past three years, its recent performance contrasts with the benchmark's modest gains. The lack of available positive or negative factors further complicates the understanding of the stock's current downward movement, suggesting that external influences or market sentiment may be impacting investor confidence.
