Why is Triveni Turbine falling/rising?

As of 16-Sep, Triveni Turbine Ltd. is currently priced at 540.40, reflecting a decline of 2.35 points or 0.43%. The stock has recently underperformed its sector by 0.85% and has experienced a trend reversal, falling after two consecutive days of gains. Despite a positive short-term performance with a 5.10% increase over the past week and a 5.73% increase over the past month, the stock has shown significant declines year-to-date and over the past year, with returns of -26.88% and -31.41%, respectively. The company's fundamentals indicate strong long-term potential, with a solid average Return on Equity (ROE) of 23.08% and a low Debt to Equity ratio. However, recent quarterly results show a concerning decline in net sales and profit after tax, which has contributed to the stock's negative performance.
In the broader market context, while the Sensex has gained 1.58% over the past week and 2.21% over the past month, Triveni Turbine's performance has lagged behind, particularly in the last year where it underperformed the market, which saw a decline of only 0.73%. The stock's valuation appears expensive with a Price to Book Value of 14.1, and despite high institutional holdings at 37.59%, the significant drop in sales and profits compared to previous quarters raises concerns among investors. This combination of factors has led to a cautious sentiment surrounding the stock, contributing to its recent price decline.
