Why is Diamond Power falling/rising?

As of 04-Aug, Diamond Power Infrastructure Ltd is experiencing a decline in its stock price, currently at Rs 165.75, down by 4.52 (-2.65%). The stock has underperformed its sector today, with a performance drop of 3.94%. After two consecutive days of gains, the stock has reversed its trend, touching an intraday low of Rs 164.8. In terms of returns, the stock has shown a positive performance over the past month with an increase of 18.82%, but it has underperformed the Sensex over the past week with a decline of 1.19%. While the company has reported positive results for the last six quarters, including a significant growth in PAT and inventory turnover, it faces challenges such as a negative book value, high debt levels, and decreasing promoter confidence, which may contribute to the recent price decline.
In the broader market context, the stock's short-term performance has lagged behind the benchmark Sensex, which has gained 0.16% over the past week. Despite the stock's strong long-term performance, including substantial returns over three and five years, the recent negative indicators, such as a decrease in promoter stake and poor long-term growth metrics, may be causing investors to reassess their positions. The combination of these factors suggests a cautious outlook for Diamond Power Infrastructure Ltd, leading to its current price drop.
