Why is Dipna Pharmachem falling/rising?

As of 16-Oct, Dipna Pharmachem Ltd's stock price is currently at Rs 20.90, reflecting a decline of Rs 1.1 or 5.0%. The stock has been underperforming, having lost 13.28% over the last three days and opening with a loss of 5% today. It has consistently traded at this price without any range, and the delivery volume has significantly decreased by 84.13% compared to the 5-day average, indicating falling investor participation. Additionally, while the stock remains above its 200-day moving average, it is below the shorter-term moving averages, suggesting a bearish trend. The stock's performance over the past week and month has also been negative, with declines of 8.13% and 4.57%, respectively, despite a strong year-to-date return of 45.04% and a remarkable 176.82% increase over the past year.
In the broader market context, the Sensex has shown positive movement, gaining 1.58% over the past week and 1.32% over the past month. This contrasts sharply with Dipna Pharmachem's recent performance, highlighting its underperformance relative to the benchmark. The stock's significant decline today and over the past few days, coupled with the broader market's upward trend, suggests that specific issues within the company are contributing to its falling price, despite its strong long-term performance.
