Despite a healthy long-term growth rate in net sales of 16.41% and a strong profit after tax growth of 94.32% in the latest six months, the stock's year-to-date return is down 11.92%, and it has generated a return of -30.00% over the past year. The stock is also trading below its moving averages across various timeframes, indicating a bearish trend.
In the broader market context, while the Sensex has only declined by 1.22% over the past week, Torrent Power's performance has been significantly worse, highlighting its struggle against the benchmark. The stock's negative returns over the past year, compared to the market's decline, suggest a lack of investor confidence, which is further reflected in the falling delivery volume, down 43.49% against the five-day average. Although the company has high institutional holdings at 39.57%, indicating some level of confidence from more knowledgeable investors, the overall sentiment remains cautious due to the stock's substantial underperformance relative to the market.
