Why is JSW Energy falling/rising?

As of 10-Jul, JSW Energy Ltd's stock price is currently at 530.60, reflecting an increase of 15.1 or 2.93%. The stock has shown a positive trend recently, gaining for the last three days with a total return of 3.95% during this period. It outperformed its sector by 2.9% today and reached an intraday high of Rs 536.3. However, despite this short-term gain, the stock has underperformed over the past month, with a return of -0.48%, and a significant decline of -26.75% over the past year. The company has high institutional holdings at 24.38%, indicating that informed investors are backing it, but it also faces challenges such as weak long-term fundamentals, a high Debt to EBITDA ratio, and disappointing recent financial results.
In the broader market context, while JSW Energy has shown a positive return in the short term, the benchmark Sensex has remained relatively flat with a return of -0.06% over the past week. This indicates that the stock's recent rise is notable compared to the broader market's performance. However, the company's long-term performance remains concerning, as it has significantly underperformed the market over the past year, with the Sensex generating a return of +4.09% during the same period. The stock's valuation appears expensive relative to its fundamentals, which may contribute to investor caution despite the recent uptick in price.
