re: KO, WMT, MCD... You scared?

Since all three are the best companies in the history of the world in their respective areas, I will continue to buy all three. Read about Warren Buffett's belief in "wide-moat" stocks and you'll feel better too

Also remember that companies such as these typically derive a large portion of their revenue from international markets. These days, poor people abroad are generally coming out of poverty, so that's likely where future growth will come from
