Why is Hemant Surgical falling/rising?

As of 09-Sep, Hemant Surgical Industries Ltd is experiencing a price increase, currently at Rs. 320.40, which reflects a rise of Rs. 6.25 or 1.99%. The stock has reached a new 52-week and all-time high today and has shown strong performance, gaining 6.16% over the past week and 36.92% over the past month. It has outperformed its sector by 2% today and has been on a consecutive gain streak for the last four days. However, there is a notable decline in investor participation, with delivery volume dropping by 91.07% compared to the 5-day average, which may indicate a potential concern regarding sustained interest in the stock.
In the broader market context, Hemant Surgical's recent performance significantly outpaces the benchmark Sensex, which has only increased by 1.18% over the past week and 1.56% over the past month. Year-to-date, the stock has surged by 153.88%, while the Sensex has only risen by 3.79%. This stark contrast highlights the stock's strong momentum relative to the market. Despite the falling delivery volume, the stock's liquidity remains adequate for trading, suggesting that while there may be some caution among investors, the overall trend is still positive.
