Why is Century Extrus. falling/rising?

As of 19-Sep, Century Extrusions Ltd is experiencing a decline in its stock price, currently at 25.73, which reflects a decrease of 0.53 or 2.02%. The stock has underperformed its sector by 1.09% today and has been on a consecutive fall for the last three days, resulting in a total decline of 4.7% during this period. Despite a positive performance over the past month with a return of 15.64%, the stock's recent movement is impacted by falling investor participation, as evidenced by a 3.06% drop in delivery volume compared to the five-day average. The company has shown strong financial metrics, including a high return on capital employed (ROCE) of 16.78% and positive results over the last three quarters, but these factors have not been enough to counteract the recent downward trend.
In the broader market context, Century Extrusions' short-term performance has lagged behind the benchmark, with a 4.10% decline over the past week compared to a 0.88% increase in the Sensex. While the stock has outperformed the benchmark over longer periods, such as a 118.24% return over three years, the current short-term underperformance may be influencing investor sentiment negatively. The stock's liquidity remains adequate for trading, but the recent price movement suggests that market participants are cautious, possibly due to the recent consecutive declines and reduced trading volume.
