Why is TD Power Systems falling/rising?

As of 25-Jul, TD Power Systems Ltd is experiencing a decline in its stock price, currently at Rs 468.00, reflecting a decrease of Rs 14.3 or 2.96%. The stock has been underperforming, having fallen consecutively for the last four days, resulting in a total decline of 5.45% over the past week. Additionally, the stock's performance today was below the sector average by 1.15%. While the stock has shown strong long-term growth with an 18.11% return over the past year and a remarkable 318.31% increase over the last three years, recent trends indicate a struggle, particularly with a significant drop in investor confidence as promoters have reduced their stake by 6.34%.
In the broader market context, TD Power Systems' short-term performance has been notably weaker compared to the benchmark Sensex, which has only declined by 0.36% over the same week. Despite the company's healthy long-term growth indicators, such as a low debt-to-equity ratio and strong profit growth, the recent decrease in promoter confidence and the stock's high valuation relative to its peers may be contributing to the current downward trend. The stock's liquidity remains adequate, but the combination of consecutive losses and reduced stakeholder confidence appears to be impacting investor sentiment negatively.
