Sarda Energy experienced a 5.1% boost today due to HDFC's 'buy' rating. The optimistic stance is based on the company's diversified model, cost optimization efforts, and promising demand outlook. HDFC predicts the stock price could range between Rs 610-664.

Sarda Energy has agreed to purchase a significant share in a hydro power company, which operates a 66 MW project, for approximately INR 250 million. This move signals Sarda's expansion into the hydropower sector.
