The McDonald's(MCD) brand has suffered over the past year with its valuation declining by 5% to $81 billion.
The brand now ranks in ninth place, falling from fifth in 2014.
The fast food chain has seen profits crumble and sales shrink as many consumers opt to eat at competitors like Chipotle(CMG), the burrito chain that McDonald's sold off almost a decade ago.
But McDonald's isn't going down without a fight. It is rejigging its menu and rebranding itself, moving away from its traditional red and yellow color palette in favor of green, said Cheung.
