Why is Yash Optics falling/rising?

As of 22-Sep, Yash Optics & Lens Ltd is experiencing a decline in its stock price, currently at Rs. 147.05, which reflects a decrease of Rs. 3.95 or 2.62%. The stock had recently reached a new 52-week high of Rs. 153.5 earlier today, indicating strong performance leading up to this point. However, the stock is now facing a drop in investor participation, with delivery volume falling by 18.7% compared to the 5-day average. Despite this decline, Yash Optics has shown impressive returns over various periods, including a 28.65% increase over the past month and a 69.02% rise year-to-date, significantly outperforming the Sensex, which has only gained 6.59% in the same timeframe.
In the broader market context, Yash Optics' short-term performance has been notably strong, with a 3.70% increase over the past week compared to a modest 0.53% rise in the Sensex. This suggests that while the stock is currently facing a price drop, it has been part of a larger upward trend in the short term. The stock's liquidity remains adequate for trading, which may help stabilize its price in the face of recent declines. Overall, the combination of a recent high, falling investor participation, and strong historical performance paints a complex picture of the stock's current movement.
