Why is TD Power Systems falling/rising?

As of 12-Sep, TD Power Systems Ltd is experiencing a decline in its stock price, currently at Rs 554.00, which reflects a decrease of 1.15 (-0.21%). The stock recently hit a new 52-week high of Rs 575.7 but has fallen after two consecutive days of gains. Today's performance shows that it underperformed its sector by 0.96%, with a day’s high of Rs 575.7 and a low of Rs 542.75. Despite a strong year-to-date return of 22.81% and a remarkable 315.35% increase over the past three years, the stock's recent movement may be influenced by a significant drop in delivery volume, which fell by 48.53% against the five-day average, indicating reduced investor participation. Additionally, while the company has demonstrated healthy growth and consistent returns, concerns regarding high valuation and decreasing promoter confidence, with a 6.34% reduction in their stake, may be contributing to the stock's recent decline.
In the broader market context, TD Power Systems' short-term performance over the past week shows a gain of 0.88%, which is lower than the Sensex's increase of 1.48%. While the stock has outperformed the benchmark over longer periods, the recent underperformance relative to the sector and the benchmark may reflect investor caution amid the declining promoter stake and high valuation metrics. Overall, the combination of strong historical performance and recent negative signals regarding investor confidence and participation suggests a complex situation for the stock's future trajectory.
