Why is Yash Highvoltage falling/rising?

As of 09-Sep, Yash Highvoltage Ltd is experiencing a decline in its stock price, currently at Rs 475.00, which reflects a decrease of Rs 9.8 or 2.02%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total decline of 5% during this period. Today's trading saw the stock reach an intraday high of Rs 494.9 and a low of Rs 466.05, with more volume traded closer to the low price. Additionally, while the stock has shown a strong year-to-date performance with a return of 77.87%, it has underperformed the sector today by 1.92% and has seen a 7.61% decline over the past week.
In the broader market context, the Sensex has shown a positive return of 1.18% over the past week and 1.56% over the past month, contrasting with Yash Highvoltage's negative returns during the same periods. This divergence indicates that the stock is not only struggling in the short term but is also lagging behind the overall market performance. Despite a rise in investor participation, as evidenced by a 26.15% increase in delivery volume against the 5-day average, the stock's recent performance suggests that market sentiment may be unfavorable, contributing to its current downward trend.
