Why is Thangamayil Jew. falling/rising?

As of 19-Nov, Thangamayil Jewellery Ltd's stock price is currently at Rs 3,178.10, reflecting a decrease of Rs 39.05 or 1.21%. The stock has been underperforming, having fallen consecutively for the last five days, resulting in a total decline of 5.65% over that period. Today's performance indicates that it has underperformed its sector by 2.29%, with an intraday low of Rs 3,142.8. Despite a strong long-term performance, with a 66.23% return over the past year and a remarkable 550.62% increase over three years, recent investor participation has decreased significantly, with delivery volume dropping by 61.56% against the five-day average. While the company has shown high management efficiency and consistent growth in net sales and profits, the current valuation appears expensive, which may be contributing to the recent price decline.
In the broader market context, the stock's short-term performance contrasts sharply with the benchmark Sensex, which has gained 0.85% over the past week. While Thangamayil Jewellery Ltd has demonstrated strong long-term growth and increasing institutional investor participation, the recent decline in stock price amidst falling investor interest and high valuation concerns may be influencing market sentiment negatively. The stock's performance relative to the Sensex suggests that while it has been a strong performer historically, current market dynamics are leading to a pullback in its price.
