Why is V-Marc India falling/rising?

As of 07-Aug, V-Marc India Ltd's stock price is currently at 431.25, reflecting a decrease of 5.45 points or 1.25%. The stock has been underperforming recently, having fallen for three consecutive days, resulting in a total decline of 10.13% during this period. Today's trading saw the stock open with a loss of 2.5% and reach an intraday low of Rs 418.1, which is a drop of 4.26%. Additionally, the stock's performance over the past week shows a decline of 5.77%, while it has performed better over the past month with a gain of 6.36%. However, the recent drop in delivery volume by 61.29% against the 5-day average indicates falling investor participation, which may contribute to the stock's downward trend.
In the broader market context, V-Marc India Ltd's short-term performance has significantly lagged behind the benchmark Sensex, which has only declined by 0.70% over the same week. While the stock has shown impressive long-term returns, such as a 1101.25% increase over the past three years, the recent underperformance relative to the benchmark and the sector suggests that investor sentiment may be shifting negatively. The stock's liquidity remains adequate for trading, but the erratic trading pattern and the current decline in investor interest could be impacting its price negatively.
