Why is Yash Optics falling/rising?

As of 18-Sep, Yash Optics & Lens Ltd is experiencing a price increase, currently at Rs. 151.00, reflecting a rise of Rs. 3.8 or 2.58%. The stock has recently hit a new 52-week and all-time high of Rs. 153.3. Despite this positive movement, it has underperformed its sector by 0.4%. The stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a strong upward trend. However, there has been a significant decline in investor participation, with delivery volume dropping by 63.89% compared to the 5-day average, which may raise concerns about sustainability. The positive and negative factors section is unavailable, limiting further insights into specific influences on the stock's movement.
Broader market context shows that Yash Optics has outperformed the benchmark Sensex significantly over various periods, with a 1-week return of 6.34% compared to the Sensex's 1.67%, and a year-to-date return of 73.56% against the Sensex's 7.52%. This strong performance relative to the benchmark suggests that the stock's rise is supported by broader investor confidence in the company, despite the recent drop in trading volume. The overall market conditions appear favorable for Yash Optics, contributing to its rising stock price.
