Why is Indokem falling/rising?

As of 22-Sep, Indokem Ltd's stock price is currently at 528.90, reflecting a decrease of 10.75, or 1.99%. The stock has been underperforming recently, having fallen for three consecutive days with a total decline of 5.86% during this period. Today's performance indicates that it has underperformed its sector by 3.02%. Despite its strong long-term performance, with a year-to-date increase of 435.87% and a one-year return of 568.22%, the stock's recent movement is marked by a decline in investor participation, as evidenced by a 27.86% drop in delivery volume compared to the five-day average. There are no available positive or negative factors to further explain the stock's recent movement.
Broader Market Context: In the short term, Indokem's performance has been notably weaker than the benchmark, with a one-week return of -2.06% compared to the Sensex's gain of 0.46%. This underperformance highlights the stock's struggle in the current market environment, despite its impressive long-term returns over one year and three years, where it significantly outperformed the Sensex. The liquidity of the stock remains adequate for trading, but the recent decline in delivery volume suggests a lack of investor confidence, contributing to the downward pressure on the stock price.
