Why is Godfrey Phillips falling/rising?

As of 10-Sep, Godfrey Phillips India Ltd. is experiencing a decline in its stock price, currently at Rs 10,785.00, reflecting a decrease of Rs 134.0 or 1.23%. Despite this drop, the stock has shown strong performance over the past week, with a return of 5.76%, and a remarkable year-to-date increase of 106.69%. However, today's trading has seen the stock underperform its sector by 1.76%, with an intraday low of Rs 10,656.8, indicating some volatility. Additionally, the stock is trading above its moving averages, suggesting a generally positive trend, but a significant drop in investor participation, with delivery volume falling by 65.23% against the 5-day average, raises concerns about current demand.
In the broader market context, the Sensex has only increased by 1.06% over the past week, indicating that Godfrey Phillips has outperformed the benchmark during this period. However, the stock's high valuation, with a Price to Book Value of 10.7, suggests it may be trading at a premium compared to its peers, which could be contributing to the recent price decline. While the company boasts strong fundamentals, including a high return on equity and consistent profit growth, the market's reaction may be tempered by its expensive valuation and declining trading volumes, which could signal caution among investors.
