Why is Bajaj Auto falling/rising?

As of 29-Jul, Bajaj Auto Ltd. is currently priced at 8,120.00, reflecting an increase of 43.5 or 0.54%. The stock has been gaining over the last two days, with a return of 0.56% during this period. However, it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a potential weakness in momentum. Additionally, there has been a notable decline in investor participation, with delivery volume falling by 30.93% compared to the 5-day average. Despite these challenges, the company maintains strong long-term fundamentals, evidenced by an average return on equity of 21.99%, healthy growth in net sales and operating profit, and a low debt-to-equity ratio. High institutional holdings at 22.39% further support the stock's stability, as these investors typically have better resources to analyze company fundamentals.
In the broader market context, Bajaj Auto's performance over the past week shows a decline of 2.09%, which is worse than the Sensex's decrease of 1.03%. Over the past month, the stock has also underperformed, with a decline of 3.82% compared to the Sensex's 3.24% drop. Year-to-date, Bajaj Auto has fallen by 7.75%, contrasting sharply with the Sensex's gain of 4.09%. This underperformance in the short term highlights the stock's challenges despite its strong long-term fundamentals and significant market presence, which constitutes 36.10% of the entire sector.
