Why is Nagpur Power falling/rising?

As of 20-Jun, Nagpur Power & Industries Ltd is experiencing a price increase, currently at Rs 120.20, reflecting a rise of Rs 6.7 or 5.9%. Today's performance indicates a trend reversal as the stock has gained after three consecutive days of decline. It reached an intraday high of Rs 124.15, showcasing a significant intraday volatility of 5.93%. Despite this positive movement today, the stock has underperformed in the short term, with a 1-week return of -3.06% and a 1-month return of -3.84%. Positive financial results, including a 175.1% growth in profit before tax and a 730.9% increase in profit after tax compared to previous quarters, have contributed to the stock's recent rise. However, the company faces challenges with weak long-term fundamentals, as indicated by a low return on equity of 3.21% and a poor EBIT to interest ratio of -2.37.
In the broader market context, while Nagpur Power has shown a short-term gain, it has lagged behind the benchmark Sensex, which has increased by 1.59% over the past week. The stock's year-to-date performance is notably poor, with a decline of 22.45%, contrasting sharply with the Sensex's gain of 5.46% in the same period. This disparity highlights the stock's volatility and the challenges it faces in maintaining investor confidence, despite today's positive movement and increased trading volume. The stock's valuation remains a concern, trading at a price-to-book value of 1.9, which is considered expensive given its low return on equity.
