Why is Restaurant Brand falling/rising?

As of 16-Jul, Restaurant Brands Asia Ltd is experiencing a price increase, currently at 84.50, reflecting a change of 0.73 or 0.87% upward. The stock has shown positive momentum, gaining 3.39% over the last three days and outperforming its sector by 2.67% today. Additionally, it has performed well in the short term, with a 1-week return of 3.68% compared to a decline of 1.08% in the Sensex. However, despite these recent gains, the stock has a concerning long-term performance, with a year-to-date return of -0.42% and a significant decline of -23.87% over the past year. The high institutional holdings at 60.81% indicate confidence from larger investors, but the company's weak long-term fundamentals, including a 0% Return on Capital Employed and a high Debt to EBITDA ratio, raise red flags about its sustainability.
In the broader market context, while Restaurant Brands Asia Ltd has shown a positive short-term return, it has consistently underperformed against the benchmark over the last three years, with a stark -25.91% return compared to the Sensex's 53.71% gain during the same period. The stock's recent upward movement contrasts with the broader market's performance, as the Sensex has seen a modest increase of 1.02% over the past month. This divergence highlights the stock's volatility and the challenges it faces in maintaining investor confidence amidst its long-term struggles.
