Why is Triveni Turbine falling/rising?

As of 18-Sep, Triveni Turbine Ltd. is experiencing a decline in its stock price, currently at 537.05, which reflects a decrease of 2.95 (-0.55%). The stock has underperformed its sector by 0.95% today and has been on a consecutive downward trend for the last three days, resulting in a total decline of 1.05% during this period. Despite a positive performance over the past week with a return of 4.53%, the stock has significantly underperformed over the year, with a return of -27.55%. The company's recent financial results show a drop in profit after tax by 27.8% and the lowest net sales recorded at Rs 371.30 cr, contributing to a perception of weakness in its financial health. Additionally, while the company maintains strong long-term fundamentals with a solid return on equity and low debt, its high valuation relative to peers and a PEG ratio of 2.7 suggest that the stock may be overvalued, which could deter investors.
In the broader market context, Triveni Turbine's short-term performance contrasts with the benchmark, as it has gained 4.53% over the past week compared to the Sensex's 1.80% increase. However, the stock's year-to-date performance is notably poor at -27.34%, while the Sensex has risen by 6.24% during the same period. This significant underperformance relative to the market indicates a lack of investor confidence, exacerbated by falling investor participation, as evidenced by an 11.05% drop in delivery volume. The overall sentiment appears to be cautious, with institutional holdings at 37.59% suggesting that while there is some institutional confidence, the broader market dynamics and recent financial results are leading to a decline in the stock's price.
