Why is TD Power Systems falling/rising?

As of 21-Jul, TD Power Systems Ltd is currently priced at 495.00, with no change in price (0.00%). The stock has underperformed its sector by 0.98% today, and its delivery volume has fallen by 23.42% compared to the 5-day average, indicating a decline in investor participation. While the stock has shown strong long-term growth with a 30.01% return over the past year and a remarkable 335.59% increase over the last three years, it has recently faced challenges, including a decrease in promoter confidence as they reduced their stake by 6.34%. Additionally, the stock is trading at a premium compared to its peers, which may contribute to its current price stagnation.
In the broader market context, the stock's short-term performance of -0.14% over the past week slightly underperforms the benchmark Sensex, which has decreased by only 0.06%. Despite the stock's strong year-to-date performance of +9.73% compared to the Sensex's +5.20%, the recent decline in investor participation and promoter confidence may be weighing on its price. Overall, while TD Power Systems has demonstrated solid growth and positive financial results, the current market sentiment and valuation concerns appear to be impacting its stock price stability.
