Why is Diamond Power falling/rising?

As of 08-Aug, Diamond Power Infrastructure Ltd's stock is currently priced at 154.10, reflecting a decrease of 2.15, or 1.38%. The stock has been underperforming, having lost 7.67% over the last three days, and today it opened with a gain of 3.07% but subsequently fell to a low of Rs 151.9. Despite touching an intraday high of Rs 161.05, the overall performance today indicates a decline, and the stock has underperformed its sector by 0.96%. In terms of returns, the stock has seen a 1.02% increase year-to-date and a 4.47% increase over the past year, but it has also experienced a significant drop of 9.65% over the past week, contrasting with the Sensex's decline of only 0.92% during the same period. The positive factor of rising investor participation, with a delivery volume increase of 45.03%, may not be sufficient to counter the recent downward trend.
Broader Market Context: In the context of the broader market, Diamond Power's short-term performance has been notably weaker than the benchmark, as evidenced by its 1-week return of -9.65% compared to the Sensex's -0.92%. This underperformance suggests that while the stock has shown some resilience over longer periods, its recent volatility and negative momentum are concerning. The liquidity of the stock remains adequate for trading, but the overall market sentiment appears to be affecting its price negatively, contributing to the recent decline.
