Why is Bajaj Finance falling/rising?

As of 26-Aug, Bajaj Finance Ltd is experiencing a decline in its stock price, currently at Rs 876.50, which reflects a decrease of Rs 24.0 or 2.67%. Today's price summary indicates that the stock underperformed its sector by 0.72%, with an intraday low of Rs 873.3, marking a drop of 3.02%. Over the past week, the stock has decreased by 2.88%, and in the last month, it has fallen by 4.07%. Despite a strong long-term performance with a year-to-date return of 28.33% and a one-year return of 29.35%, the stock is currently facing pressure due to its recent underperformance relative to the finance/NBFC sector, which has declined by 2.02%. Additionally, there has been a notable drop in investor participation, with delivery volume falling by 14.21% compared to the five-day average.
In the broader market context, the stock's short-term performance has been weaker than the benchmark, as it has declined more significantly than the Sensex, which fell by only 1.05% over the past week. While Bajaj Finance has demonstrated strong fundamentals, including a healthy return on equity and consistent positive results over the last 16 quarters, its current valuation appears expensive with a price-to-book ratio of 5.6, which may deter some investors. The stock's recent movement reflects a combination of sector-wide pressures and a decline in trading activity, despite its overall strong historical performance and institutional backing.
