Why is Reliance Power falling/rising?

As of 05-Sep, Reliance Power Ltd's stock price is currently at 46.92, reflecting an increase of 0.52 (1.12%). The stock has shown strong performance recently, outperforming its sector by 0.98% today. Over the past week, it has risen by 6.78%, and year-to-date, it has generated a return of 10.24%. Positive factors contributing to this rise include a significant increase in profit after tax to Rs 170.25 crore and a record return on capital employed at 5.95%. Additionally, the stock is trading at a discount compared to its peers' historical valuations, which may attract investors despite concerns over its long-term fundamental strength and high debt levels.
In the broader market context, while the BSE500 index has experienced negative returns of -4.41% over the past year, Reliance Power has managed to deliver a remarkable return of 51.99%, indicating strong market-beating performance. However, the stock's recent increase comes amid a decline in investor participation, with delivery volume falling by 16.46% against the 5-day average. This suggests that while the stock is currently rising, there may be underlying concerns regarding its long-term sustainability and investor confidence, particularly given the low stake held by domestic mutual funds.
