Why is Sheetal Univer. falling/rising?

As of 17-Sep, Sheetal Universal Ltd is experiencing a price increase, currently trading at Rs 135.00, which reflects a rise of Rs 2.5 or 1.89%. The stock has shown strong performance recently, with a 10.02% increase over the past week, significantly outperforming the Sensex, which only rose by 1.43% in the same period. Additionally, the stock is currently trading close to its 52-week high, just 2.59% away from Rs 138.5. However, there has been a notable decline in investor participation, with delivery volume dropping by 34.21% compared to the 5-day average, which could indicate a potential concern for future trading activity.
In the broader market context, Sheetal Universal Ltd's year-to-date return of 86.72% far exceeds the Sensex's 7.13%, highlighting its strong performance relative to the market. While the stock has outperformed the sector by 2.22% today, the overall market sentiment appears to be mixed, as the Sensex has only shown a modest gain. This divergence suggests that while Sheetal Universal Ltd is currently on an upward trajectory, the decrease in trading volume may raise questions about sustainability in the face of broader market trends.
