When I buy a stock. I don't compare McDonald's performance since 1965 to Arm's performance since 2023.
If that's what you suggests? The start date is the same as of what I can see.
Or are you saying that one should compare the first 2 years of McDonald's IPO from 1965-1967 with Arm from 2023-2025. To figure out if McDonald is a good investment comparable to Arm today???
