Why is DLF falling/rising?

As of 12-Aug, DLF Ltd. is experiencing a decline in its stock price, currently at 756.25, which reflects a decrease of 8.65 points or 1.13%. The stock has underperformed its sector by 0.49% today and is trading below its moving averages across various time frames. Over the past week, DLF has seen a return of -3.13%, and its performance over the last month is down by 7.20%. Despite a healthy long-term growth rate in operating profit and positive results over the last four quarters, the stock's valuation appears expensive with a Price to Book Value of 4.4, which may be contributing to the downward pressure on its price.
In the broader market context, DLF's recent performance contrasts with the Sensex, which has only declined by 0.59% over the same week. The company's low debt-to-equity ratio and high institutional holdings indicate a strong fundamental position; however, the stock's year-to-date return of -8.29% starkly contrasts with the Sensex's gain of 2.68%. This discrepancy suggests that while the company has solid fundamentals, investor sentiment may be negatively influenced by its high valuation relative to peers and the recent underperformance in stock returns.
