Why is Restaurant Brand falling/rising?

As of 23-Jun, Restaurant Brands Asia Ltd is experiencing a price increase, currently at 80.71, reflecting a rise of 0.82 or 1.03%. The stock has shown a positive trend recently, gaining 6.63% over the last three days and outperforming its sector by 0.49% today. Despite this short-term gain, the stock has underperformed in the longer term, with a decline of 24.68% over the past year and 22.32% over the last three years. The company has high institutional holdings at 60.81%, which have increased by 6.62% in the previous quarter, suggesting a level of confidence from these investors. However, the stock's long-term fundamentals are weak, with a Return on Capital Employed (ROCE) of 0% and a high Debt to EBITDA ratio of 5.02 times, indicating challenges in servicing debt and poor growth prospects.
In the broader market context, the stock's short-term performance of +3.62% over the past week contrasts with the Sensex's modest gain of +0.12%, highlighting a stronger short-term recovery relative to the benchmark. However, the stock's year-to-date performance remains negative at -4.89%, while the Sensex has increased by 4.81% during the same period. This consistent underperformance against the benchmark over the last three years, coupled with negative operating profits and a low ability to service debt, raises concerns about the stock's sustainability despite recent gains.
