Why is P & G Health Ltd falling/rising?

As of 22-Aug, Procter & Gamble Health Ltd is experiencing a price increase, currently at 6,573.80, reflecting a rise of 224.05 or 3.53%. The stock has recently hit a new 52-week high of Rs. 6677 and has outperformed its sector by 3.19%. Over the past week, the stock has gained 4.57%, and it has shown a strong performance with a 25.98% return over the past year. The company has demonstrated high management efficiency with a return on equity (ROE) of 32.32% and has maintained a low debt-to-equity ratio. Additionally, it has reported positive results for the last four consecutive quarters, contributing to its upward momentum. However, there are concerns regarding its long-term growth, as net sales have only grown at an annual rate of 7.39% over the last five years.
In the broader market context, Procter & Gamble Health Ltd has significantly outperformed the benchmark Sensex, which has only risen by 0.88% over the past week, while the stock has gained 4.57%. This trend continues in the longer term, with the stock generating a 25.69% return year-to-date compared to the Sensex's 4.05%. Despite the positive short-term performance, the stock's valuation appears expensive with a price-to-book value of 20.3, which may raise concerns among investors. Additionally, a decline in investor participation, as indicated by a 16.38% drop in delivery volume, could pose risks to its continued upward trajectory.
