Why is Godfrey Phillips falling/rising?

As of 18-Sep, Godfrey Phillips India Ltd. is experiencing a decline in its stock price, currently at Rs 3,493.95, which reflects a decrease of Rs 78.3 or 2.19%. The stock has underperformed its sector by 2.46% today and has been on a consecutive downward trend for the last two days, resulting in a total drop of 4.13%. Despite this recent decline, the stock has shown strong performance over the longer term, with a year-to-date increase of 102.91% and a remarkable 861.82% rise over the past three years. The company has demonstrated high management efficiency, a low debt-to-equity ratio, and consistent growth in net profit and operating profit, which are positive indicators for its long-term prospects. However, the stock is considered expensive relative to its peers, with a high price-to-book value, which may contribute to the recent price pressure.
In the broader market context, the stock's short-term performance has lagged behind the benchmark Sensex, which has risen by 1.80% over the past week compared to Godfrey Phillips' 1.76% increase. This slight underperformance may reflect broader market dynamics affecting investor sentiment. Additionally, while the stock has shown significant growth in the past year, the recent price decline could be attributed to profit-taking or concerns over its high valuation metrics, particularly given the company's PEG ratio of 1.3, indicating that the stock may be trading at a premium compared to its historical valuations.
