Why is Bajaj Auto falling/rising?

As of 18-Sep, Bajaj Auto Ltd. is currently priced at Rs 9,075.00, reflecting a decrease of Rs 5.0 or 0.06%. The stock has underperformed its sector by 0.52% today and has experienced a trend reversal, falling after three consecutive days of gains. It has traded within a narrow range of Rs 85.05. Additionally, the stock's delivery volume has significantly decreased by 62.18% compared to the five-day average, indicating falling investor participation. Over the past year, Bajaj Auto has seen a substantial decline of 22.89% in returns, although it has shown a positive return of 5.77% over the past month. The company maintains strong long-term fundamentals, with a healthy return on equity (ROE) of 21.03% and a low debt-to-equity ratio, but its profits have declined by 5.2% in the last year, which may contribute to the current price movement.
In the broader market context, Bajaj Auto's short-term performance has lagged behind the benchmark Sensex, which has gained 1.80% over the past week while Bajaj Auto has decreased by 0.55%. Despite being the largest company in its sector and holding a significant market share, the recent drop in stock price may reflect investor concerns over declining profits and reduced trading activity. The stock's attractive valuation, with a price-to-book value of 7.2, suggests it is trading fairly compared to peers, yet the high institutional holdings at 22.39% may not be enough to offset the negative sentiment stemming from recent performance metrics.
