Why is Aditya AMC falling/rising?

As of 18-Jul, Aditya Birla Sun Life AMC Ltd's stock price is currently at 866.45, reflecting an increase of 2.85, or 0.33%. The stock has shown strong performance, with a 1-week return of +1.82% and a 1-month return of +15.64%, significantly outperforming the Sensex, which has seen a decline of -0.90% over the same week. Additionally, the stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. Despite a slight decrease in delivery volume by 7.34% compared to the 5-day average, the stock maintains strong long-term fundamentals, evidenced by an average Return on Equity (ROE) of 25.98%. The majority ownership by promoters further supports investor confidence, contributing to the stock's upward movement.
In the broader market context, Aditya AMC's recent performance stands out, particularly in the short term where it has outperformed the Sensex, which has only gained 0.38% over the past month. The stock's year-to-date return of +3.77% is slightly below the Sensex's +4.63%, but its 1-year return of +22.54% far exceeds the Sensex's modest +0.51%. This consistent outperformance over various time frames, including a remarkable +107.11% return over the last three years, positions Aditya AMC favorably against broader market trends, reinforcing its appeal to investors amidst a fluctuating market environment.
