Why is Yash Highvoltage falling/rising?

As of 11-Sep, Yash Highvoltage Ltd's stock price is currently at 482.50, reflecting a decrease of 2.5, or 0.52%. The stock has underperformed its sector today by 2.05%, and its delivery volume has significantly dropped by 61.54% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has declined by 1.64%, and over the past month, it has fallen by 8.03%. Despite a strong year-to-date performance of 80.68%, the recent trends suggest a weakening momentum, particularly as it is currently below its 5-day, 20-day, and 50-day moving averages, although it remains above the 100-day and 200-day moving averages.
In the broader market context, the Sensex has shown a positive return of 1.03% over the past week and 1.17% over the past month, contrasting sharply with Yash Highvoltage's negative returns during the same periods. This underperformance relative to the benchmark indicates that the stock is not keeping pace with the overall market, which may be contributing to investor concerns. The liquidity of the stock remains adequate for trading, but the significant drop in delivery volume suggests a lack of confidence among investors, further exacerbating the stock's decline.
