Why is Triveni Turbine falling/rising?

As of 12-Aug, Triveni Turbine Ltd. is experiencing a decline in its stock price, currently at 516.20, which reflects a decrease of 5.15 points or 0.99%. The stock has underperformed its sector by 1.04% today and has been on a consecutive downward trend for the last two days, accumulating a total loss of 2.23%. Over the past week, the stock has fallen by 3.24%, and its performance over the last month shows a significant decline of 19.88%. The company has reported a drop in net sales and profit after tax, with net sales falling by 26.0% and PAT decreasing by 27.8% compared to the previous four-quarter average. Despite having strong long-term fundamentals, including a solid return on equity and low debt-to-equity ratio, the stock's valuation appears expensive, which may be contributing to investor hesitation.
In the broader market context, Triveni Turbine's performance has lagged behind the benchmark Sensex, which has only declined by 0.59% over the past week. The stock's year-to-date performance shows a substantial drop of 30.16%, contrasting sharply with the Sensex's gain of 2.68%. This underperformance is further highlighted by the stock's returns over the last year, where it has decreased by 26.07% compared to the market's slight negative return of 2.11%. The falling investor participation, indicated by a significant drop in delivery volume, suggests a lack of confidence among investors, which is likely exacerbating the stock's decline.
