Why is Thyrocare Tech. falling/rising?

As of 10-Jul, Thyrocare Technologies Ltd is experiencing a decline in its stock price, currently at 1,083.45, down by 7.55 points or 0.69%. Despite this decrease, the stock has shown strong performance over the past week, rising by 6.01%, and has outperformed the sector by 0.31% today. The stock is also close to its 52-week high, just 1.66% away from Rs 1,101.45. It has been trading above all its moving averages, indicating a generally positive trend. However, the company faces challenges such as a long-term growth rate of operating profit that has declined by 0.80% annually over the last five years and a high valuation with a Price to Book Value of 10.5, which may deter some investors.
In the broader market context, while Thyrocare Technologies has outperformed the Sensex with a year-to-date return of 18.71% compared to the Sensex's 6.46%, the stock's recent decline may be influenced by the overall market sentiment and the risks associated with high promoter pledged shares, which can exert downward pressure in falling markets. The stock's strong historical performance, including a 70.42% return over the past year, contrasts with its current price movement, suggesting that while the company has been successful in the long term, short-term fluctuations and market conditions are affecting its stock price.
