Why is Restaurant Brand falling/rising?

As of 19-Sep, Restaurant Brands Asia Ltd is currently priced at 86.09, reflecting an increase of 0.24 (0.28%). The stock has been gaining momentum, having outperformed its sector by 0.91% today and achieving a consecutive gain over the last two days, with a total return of 7.49% during this period. Additionally, the stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating positive short-term momentum. However, despite these gains, the company faces challenges, including a weak long-term fundamental strength characterized by an average Return on Capital Employed (ROCE) of 0%, a high Debt to EBITDA ratio of 5.02 times, and consistent underperformance against benchmarks over the past three years.
In the broader market context, the stock has shown a strong short-term return of 6.15% over the past week, significantly outperforming the Sensex, which has only increased by 0.88% during the same period. However, the stock's year-to-date performance remains modest at 1.45%, lagging behind the Sensex's 5.74% increase. This contrast highlights the stock's volatility and the mixed signals it presents to investors, as it has generated a negative return of -19.50% over the past year while still attracting high institutional holdings at 60.5%. The combination of short-term gains and long-term weaknesses creates a complex picture for potential investors.
