Why is Aarti Surfactant falling/rising?

As of 20-Oct, Aarti Surfactants Ltd is experiencing a price increase, with the current price at Rs 477.60, reflecting a rise of Rs 27.3 or 6.06%. Today's performance indicates a trend reversal as the stock has gained after two consecutive days of decline. It outperformed its sector by 5.5% and reached an intraday high of Rs 495, marking a significant increase of 9.93%. However, despite this positive movement, the stock has shown a negative return of 2.46% over the past month and a substantial decline of 25.16% year-to-date. Additionally, there has been a decrease in investor participation, with delivery volume falling by 4.59% against the five-day average, which may indicate some caution among investors.
Broader market context shows that Aarti Surfactants Ltd's short-term return of 4.33% over the past week outperformed the Sensex, which gained 2.47% in the same period. However, the stock's longer-term performance remains concerning, with a year-to-date decline of 25.16% compared to the Sensex's increase of 7.97%. This contrast highlights the stock's struggles relative to the broader market, despite today's positive movement. The liquidity of the stock appears sufficient for trading, as it is liquid enough for a trade size of Rs 0 crore based on 2% of the five-day average traded value.
