Why is Diamond Power falling/rising?

As of 24-Jun, Diamond Power Infrastructure Ltd's stock price is currently at Rs 110.05, reflecting an increase of Rs 3.25 or 3.04%. The stock has been on an upward trend, gaining for the last three days with a total return of 9.18% during this period. It has outperformed its sector by 2.15% today and reached an intraday high of Rs 110.9. Additionally, the stock has shown strong performance over the past week and month, with returns of 6.07% and 15.84%, respectively. Positive factors contributing to this rise include the company's consistent positive results over the last six quarters, with a significant growth in profit after tax and a high inventory turnover ratio. However, the company also faces challenges such as a negative book value and high debt levels, which may impact long-term investor confidence.
In the broader market context, Diamond Power's recent performance stands in stark contrast to the benchmark Sensex, which has only increased by 0.58% over the past week and 0.41% over the past month. Despite the stock's strong short-term gains, it has underperformed the market over the past year, with a return of -7.72% compared to the Sensex's 6.10%. This underperformance, combined with the lack of investment from domestic mutual funds, suggests that while the stock is currently rising, there are underlying concerns regarding its long-term viability and market perception.
