Why is Triveni Turbine falling/rising?

As of 22-Sep, Triveni Turbine Ltd. is experiencing a price increase, currently at Rs 539.85, reflecting a change of 3.7 (0.69%) upward. The stock has shown a trend reversal, gaining after four consecutive days of decline, and has outperformed its sector by 1.53%. Despite this positive movement today, the stock has underperformed in the short term, with a 1-week return of -0.53% compared to the Sensex's +0.46%. Over the past month, however, it has gained 1.29%, slightly better than the Sensex's 1.05%. The stock's long-term fundamentals remain strong, evidenced by an average Return on Equity (ROE) of 23.08% and a low Debt to Equity ratio, but it faces challenges with a significant drop in PAT and net sales in the latest quarter.
In the broader market context, while the stock has shown some recovery today, it has significantly underperformed the market over the past year, with a return of -26.23% compared to the BSE500's -3.80%. This stark contrast highlights the stock's struggles despite its strong institutional backing, which stands at 37.59%. The valuation concerns, indicated by a high Price to Book Value ratio of 14.1 and a PEG ratio of 2.7, suggest that the stock may be considered expensive relative to its earnings growth. Overall, while today's price movement indicates a positive shift, the underlying financial performance and market conditions suggest a cautious outlook for Triveni Turbine Ltd.
