Why is Diamond Power falling/rising?

As of 18-Jul, Diamond Power Infrastructure Ltd's stock is currently priced at Rs 168.60, reflecting a decline of Rs 6.75 or 3.85%. The stock has been underperforming, having lost 6.02% over the last two days and touching an intraday low of Rs 167.75. Despite a strong performance in the longer term, with a 63.77% increase over the past month and a remarkable 91035.14% rise over three years, the stock's recent movement is influenced by a negative book value and high debt levels, which raise concerns about its long-term fundamental strength. Although the company has reported positive results for the last six consecutive quarters, including a 67.23% growth in PAT, the negative net worth and poor long-term growth in net sales at an annual rate of -11.40% are significant red flags for investors.
In the broader market context, the stock has outperformed the benchmark Sensex in the short term, with a 2.09% increase over the past week compared to a 0.90% decline in the index. However, the recent consecutive falls and declining investor participation, evidenced by a 17.87% drop in delivery volume against the five-day average, suggest a lack of confidence among investors. Additionally, the absence of domestic mutual fund holdings indicates that institutional investors may be wary of the stock's current valuation and business prospects, further contributing to its downward pressure.
