Why is Yash Optics falling/rising?

As of 08-Sep, Yash Optics & Lens Ltd is experiencing a price increase, currently at Rs 134.00, which represents a rise of Rs 6.35 or 4.97%. The stock has shown strong performance, outpacing the sector by 6.69% today and is trading above all key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages. Over the past week, the stock has increased by 4.28%, and over the past month, it has surged by 44.55%. However, there has been a notable decline in investor participation, with delivery volume dropping by 45.95% compared to the 5-day average, which may indicate a potential concern for sustained momentum.
In the broader market context, Yash Optics has significantly outperformed the benchmark Sensex, which has only risen by 0.60% over the past week. Year-to-date, the stock has gained 54.02%, while the Sensex has increased by just 4.77%. This strong relative performance suggests that investor sentiment towards Yash Optics remains positive despite the recent drop in delivery volume. The stock is also close to its 52-week high, being only 2.99% away from Rs 138, indicating continued bullish sentiment among investors. Overall, while the stock is rising, the decline in trading volume could be a factor to monitor moving forward.
