Why is Indian Emuls falling/rising?

As of 19-Sep, Indian Emulsifiers Ltd is experiencing a significant rise in its stock price, currently at 193.65, reflecting an increase of 20.75 or 12.0%. The stock has outperformed its sector by 12.33% today and is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a strong upward momentum. However, there has been a decline in investor participation, with delivery volume dropping by 25.93% against the 5-day average. Over the past month, the stock has shown a remarkable return of 35.42%, contrasting sharply with its year-to-date performance, which is down 15.33%.
In the broader market context, Indian Emulsifiers Ltd's short-term return of 0.94% over the past week slightly outpaces the Sensex's return of 0.85%. Despite the stock's recent gains, it has underperformed the benchmark significantly over longer periods, with a year-to-date decline of 15.33% compared to the Sensex's increase of 7.11%. This suggests that while the stock is currently on an upward trajectory, it has faced challenges in the longer term, which may affect investor sentiment moving forward.
