Why is Apollo Hospitals falling/rising?

As of 19-Aug, Apollo Hospitals Enterprise Ltd. is experiencing a decline in its stock price, currently at Rs 7,815.00, which reflects a decrease of Rs 36.0 or 0.46%. Despite this drop, the stock has shown strong performance over the past week, gaining 7.39%, and has outperformed the benchmark Sensex, which increased by only 1.76%. The stock is close to its 52-week high, just 1.3% away, but has recently underperformed its sector by 0.61%. After five consecutive days of gains, the stock has entered a trend reversal, trading within a narrow range of Rs 60.65. Notably, it is trading above all key moving averages, and there has been a rise in investor participation, with delivery volume increasing by 18.63% compared to the five-day average.
In the broader market context, while Apollo Hospitals has shown impressive returns over various periods, including a 16.29% increase over the past year, the overall market sentiment may be influencing its current price movement. The stock's recent performance is contrasted by the Sensex's modest gain of 1.76% over the same week. The company's strong fundamentals, such as a high return on capital employed (ROCE) of 15.08% and consistent growth in net sales and operating profit, suggest a solid long-term outlook. However, the recent price decline could reflect profit-taking after a period of strong gains, despite the stock's attractive valuation compared to peers and high institutional holdings at 65.05%.
