Why is Torrent Power falling/rising?

As of 04-Sep, Torrent Power Ltd. is currently priced at 1,295.30, reflecting a decrease of 20.7 points or 1.57%. The stock has recently underperformed its sector by 0.4% and has experienced a trend reversal, falling after three consecutive days of gains. In terms of performance, the stock has shown a 3.84% increase over the past week, but it has declined by 1.32% over the past month and significantly by 25.52% over the past year. Additionally, the stock's delivery volume has decreased by 67.49% compared to the five-day average, indicating falling investor participation. While the company has a fair valuation with a return on capital employed (ROCE) of 15.1 and a PEG ratio of 1.6, it has also faced challenges, including a substantial drop in profit before tax and net sales in its latest quarterly results.
Broader market context shows that while the stock has underperformed the market over the past year, with a return of -25.52% compared to the BSE500's -4.38%, it has outperformed the benchmark in the short term, gaining 3.84% over the last week against the Sensex's 0.80%. Despite the stock trading at a discount compared to its peers' average historical valuations and having high institutional holdings at 39.57%, the recent financial results have raised concerns among investors. The combination of declining sales and profits, along with a significant drop in trading volume, suggests that investor sentiment is currently negative, contributing to the stock's recent price decline.
