Why is Diamond Power falling/rising?

As of 08-Jul, Diamond Power Infrastructure Ltd's stock price is rising, currently at Rs 147.45, reflecting an increase of Rs 2.2 or 1.51%. The stock has shown strong performance recently, gaining 6.85% over the past week and outperforming its sector by 1.88%. It has also been on a consecutive gain streak for the last five days, reaching an intraday high of Rs 149.9. The company has reported positive results for the last six consecutive quarters, with a significant growth in PAT and net sales, contributing to its recent upward momentum. However, it is important to note that the company has a negative book value and high debt levels, which could pose risks for long-term investors.
In the broader market context, Diamond Power's short-term return of 6.85% over the past week significantly outpaces the Sensex, which has only seen a marginal increase of 0.02%. While the stock has generated a return of 19.03% over the past year, it has underperformed compared to the Sensex year-to-date, which has risen by 7.13%. Despite its recent gains, the stock's long-term fundamentals are concerning due to its negative net worth and poor growth rates in net sales over the past five years, which may deter some investors. The lack of domestic mutual fund investment further indicates a cautious sentiment towards the stock's valuation and business stability.
