Why is Thyrocare Tech. falling/rising?

As of 12-Sep, Thyrocare Technologies Ltd is experiencing a decline in its stock price, currently at Rs 1,218.70, which reflects a decrease of Rs 38.05 or 3.03%. The stock has been underperforming, having fallen consecutively for the last six days, resulting in a total decline of 9.52% during this period. Today's trading saw the stock reach an intraday high of Rs 1,286.5 but also dip to a low of Rs 1,218. The stock's performance over the past week shows a decrease of 8.18%, while it has outperformed the benchmark Sensex over the year with a return of 41.31%. However, the company faces challenges, including a high valuation relative to its peers and the fact that 100% of promoter shares are pledged, which can exert additional downward pressure on the stock price.
In the broader market context, the Sensex has shown a positive return of 1.48% over the past week, contrasting sharply with Thyrocare's decline. This underperformance relative to the benchmark indicates that investor sentiment may be shifting away from the stock, particularly given the recent drop in delivery volume by 43.63% against the five-day average, suggesting falling investor participation. Although the company has demonstrated strong management efficiency and positive financial results in recent quarters, the long-term growth concerns and high valuation metrics may be contributing to the current downward trend in its stock price.
