MCD - McDonalds will manage to eke out a small gain over the decade, and be the winner of the 2020's.

Following a recession, all new investors will panic and withdraw all their money and keep it out for years. They didn't know the market could be down two years in a row. Boomers reach a phase in their lives where they are only taking money out of the stock market, and spending it on Chinese goods. Inflation picks up, and smart money moves from stocks to gold and then bonds. This combination will lead to one of the worst decades for stocks since the great depression. 2028 and 2029 sees money starting to go back into the market. But the decade as a whole sees low gains.

But even in a recession, people still treat themselves by eating out at McDonalds and their new $5 Keto menu.
