Why is V-Marc India falling/rising?

As of 15-Sep, V-Marc India Ltd's stock price is currently at 457.25, reflecting an increase of 9.95, or 2.22%. The stock has outperformed its sector by 1.17% today, and it is trading above its 5-day, 50-day, 100-day, and 200-day moving averages, although it is below the 20-day moving average. Despite this positive movement, there has been a notable decline in investor participation, with delivery volume dropping by 28.57% compared to the 5-day average. Over the past week, the stock has gained 3.17%, while it has seen a decline of 5.63% over the past month. Year-to-date, the stock has performed well, with a return of 19.28%, significantly outpacing the benchmark Sensex, which has returned 6.02%.
In the broader market context, V-Marc India's recent performance indicates a strong recovery compared to the benchmark, particularly in the short term, where it has outperformed the Sensex by 2.97% over the past week. The stock's impressive 3-year return of 1197.16% further highlights its strong performance relative to the Sensex's 40.23% over the same period. However, the decline in delivery volume may suggest a potential concern regarding sustained investor interest, which could impact future price movements. Overall, while the stock is currently rising, the decrease in trading activity may warrant close monitoring to assess its long-term viability.
