Why is Bajaj Housing falling/rising?

As of 04-Sep, Bajaj Housing Finance Ltd is currently priced at 112.05, reflecting a decrease of 1.25, or 1.1%. The stock has underperformed its sector today by 1.51% and has experienced a trend reversal, falling after three consecutive days of gains. It is trading below all key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages. Additionally, investor participation has decreased, with delivery volume dropping by 13.04% compared to the 5-day average. Over the past month, the stock has declined by 1.93%, while the benchmark Sensex has only decreased by 0.37%.
In terms of broader market context, the stock's year-to-date performance shows a significant decline of 12.08%, contrasting sharply with the Sensex's gain of 3.30%. Despite the company's strong long-term fundamentals, including a 27.65% CAGR growth in operating profits and positive results over the last three quarters, the stock's high valuation, indicated by a price-to-book value of 4.7 and a return on equity of 10.8%, raises concerns among investors. This combination of underperformance relative to the market and high valuation metrics contributes to the stock's current downward movement.
