Why is Archean Chemical falling/rising?

As of 21-Jul, Archean Chemical Industries Ltd is experiencing a price increase, currently at 700.15, reflecting a change of 2.5 (0.36%) upward. The stock has shown strong performance recently, outperforming its sector by 0.73% today and achieving consecutive gains over the last two days with a total return of 2.14%. Over the past week, the stock has risen by 1.99%, and in the last month, it has increased by 10.70%, while year-to-date returns stand at 4.52%. The company benefits from high management efficiency, evidenced by a return on capital employed (ROCE) of 28.54%, and a low debt-to-equity ratio, which supports its stability. Additionally, institutional holdings have increased by 0.62% over the previous quarter, indicating confidence from larger investors.
In the broader market context, the Sensex has shown a slight decline of 0.06% over the past week and a marginal drop of 0.25% over the past month, contrasting with Archean's positive returns during the same periods. This divergence suggests that Archean is gaining traction despite a generally weak market environment. However, it is worth noting that investor participation has decreased, with delivery volume falling by 11.39% against the five-day average, which could indicate a potential concern for future liquidity. Nonetheless, the stock remains liquid enough for trading, which may help sustain its upward momentum in the near term.
