Why is Diamond Power falling/rising?

As of 19-Sep, Diamond Power Infrastructure Ltd is experiencing a price increase, currently at Rs 161.85, reflecting a rise of Rs 10.45 or 6.9%. The stock has shown a positive trend today, gaining after three consecutive days of decline, and it outperformed its sector by 6.52%. It reached an intraday high of Rs 163.55, indicating strong intraday performance. Over the past week, the stock has increased by 7.72%, and it has consistently outperformed the BSE500 over the last three years, with a remarkable 83327.84% return over that period. However, the company has a negative book value and high debt levels, which raises concerns about its long-term fundamental strength despite positive quarterly results and consistent returns.
Broader market context shows that while Diamond Power has performed well in the short term, the broader market, represented by the Sensex, has only increased by 0.88% over the past week. This indicates that the stock's recent performance is significantly stronger than the overall market. However, the decline in promoter confidence, as evidenced by a 5.98% reduction in their stake, coupled with a negative long-term growth outlook, presents a contrasting narrative to its current price rise. The stock's liquidity remains adequate, but the falling investor participation suggests caution among traders.
