Why is Maruti Sec. falling/rising?

As of 29-Aug, Maruti Securities Ltd is experiencing a price increase, currently at Rs 76.04, which reflects a rise of 3.62 or 5.0%. The stock has been on a strong upward trend, gaining 142.17% over the last 20 days and outperforming its sector by 5.66% today. It has also reached a new 52-week and all-time high of Rs 76.04. Additionally, the stock is trading above its moving averages across various time frames, indicating strong momentum. However, it is important to note that the company has a negative book value and weak long-term fundamental strength, with a significant decline in profit after tax in the latest quarter, which could raise concerns among investors.
In the broader market context, Maruti Securities has significantly outperformed the benchmark Sensex, which has seen a decline of 1.84% over the past week and 1.88% over the past month, while Maruti's stock has surged by 21.51% and 134.69% respectively during the same periods. This stark contrast highlights the stock's strong performance relative to the overall market, driven by rising investor participation and liquidity. Despite the positive short-term performance, the company's long-term fundamentals remain questionable, which could impact future investor sentiment.
