Why is Yash Highvoltage falling/rising?

As of 02-Jul, Yash Highvoltage Ltd's stock price is rising, currently at Rs 399.50, reflecting an increase of Rs 30.5 or 8.27%. The stock has shown strong performance, gaining 9.45% over the last two days and is only 0.63% away from its 52-week high of Rs 402. It has outperformed its sector by 9.03% today and is trading above all key moving averages, indicating a bullish trend. However, there has been a notable decline in investor participation, with delivery volume dropping by 51.95% compared to the 5-day average, which may suggest caution among some investors.
In the broader market context, Yash Highvoltage's 1-week return of 4.04% significantly outpaces the Sensex's 0.79% increase, and its 1-month return of 33.17% is also well above the Sensex's 2.50%. Year-to-date, the stock has risen by 49.60%, compared to the Sensex's 6.75%, highlighting its strong performance relative to the market. This robust performance, combined with the stock's recent upward movement, suggests that investor sentiment remains positive despite the drop in trading volume.
