Why is Dishman Carbogen falling/rising?

As of 26-Sep, Dishman Carbogen Amcis Ltd is currently priced at 280.50, reflecting a decline of 14.6 points or 4.95%. The stock has been on a downward trend, having underperformed its sector by 2.61% today and experiencing a consecutive fall over the last four days, resulting in a total drop of 10.7%. The stock opened with a loss of 2.41% and reached an intraday low of Rs 280.35. Despite its strong performance over the past year, with a return of 53.49% and significant profit growth, the recent decline is attributed to a sharp decrease in investor participation, with delivery volume plummeting by 87.95% against the five-day average.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, with a one-week return of -6.55% compared to the Sensex's -2.66%. The Pharmaceuticals & Drugs sector has also faced a decline of 2.34%, contributing to the stock's struggles. Although Dishman Carbogen has demonstrated strong long-term performance and attractive valuations, the recent negative sentiment and falling investor participation have overshadowed these positives, leading to its current price drop.
