Why is Archean Chemical falling/rising?

As of 18-Jul, Archean Chemical Industries Ltd is experiencing a price increase, currently at Rs 697.65, reflecting a rise of 12.15 (1.77%). The stock has shown a positive trend today, outperforming its sector by 2.8% and reversing a two-day decline. It reached an intraday high of Rs 700.5, indicating strong performance. Over the past week, the stock has gained 4.21%, while over the past month, it has risen by 12.82%. Despite a year-to-date increase of 4.14%, the stock has seen a slight decline of 0.41% over the past year. The company benefits from high management efficiency, evidenced by a return on capital employed (ROCE) of 28.54%, a low debt-to-equity ratio, and increased institutional holdings, which have risen by 0.62% in the last quarter.
In the broader market context, the Sensex has declined by 0.90% over the past week, contrasting with Archean's positive performance. While the stock has shown resilience and growth, the overall market sentiment appears weaker, as indicated by the benchmark's performance. The decrease in delivery volume by 42.87% against the five-day average suggests a potential concern regarding investor participation, which could affect future price movements. Nonetheless, the liquidity of the stock remains adequate for trading, supporting its current upward trend.
