Pick a stock. Any stock. Show me the stock ticker symbol by EOD tomorrow, reflect a purchase price of 12/31/2018 and purchase a fantasy $10,000 worth. I'll purchase a fantasy of $10,000 of FDX.
EOM next December, which is Dec 31 for all you, ah, never mind. If your money is worth more than mine, I'll give you $100. If mine is worth more than yours, you give me $100.
Just pony up the symbol and close price today and I'll do the same for FDX. We'll see in exactly one year who has done better.
