Why is Archean Chemical falling/rising?

As of 24-Jul, Archean Chemical Industries Ltd is experiencing a decline in its stock price, currently at Rs 679.95, reflecting a decrease of Rs 12.3 or 1.78%. The stock has underperformed its sector by 1.63% today, having touched an intraday low of Rs 678.25. Over the past week, the stock has decreased by 0.81%, while it has shown a positive return of 10.09% over the past month. Despite this recent decline, the company maintains a high management efficiency with a return on capital employed (ROCE) of 28.54% and a low debt-to-equity ratio, which suggests financial stability. Additionally, institutional holdings have increased by 1.61% over the previous quarter, indicating confidence from larger investors.
In the broader market context, the Sensex has shown a minimal decline of 0.09% over the past week, which suggests that the market conditions are relatively stable. However, Archean Chemical's performance over the past year has been disappointing, with a decline of 8.26% compared to a 2.54% increase in the Sensex. This underperformance may be contributing to the stock's current downward movement. The stock's liquidity remains adequate, with a delivery volume that has risen by 3.64% against the five-day average, indicating some investor interest despite the recent price drop.
