Costco reported earnings last week on December 10 and killed analyst expectations! Revenues increased 16.6% Y/Y by billions of dollars and they also beat earnings per share expectations by $0.25. Since the beginning of the year Costco stock has had a phenomenal run. It's up 27% and that's especially astounding after considering the market's drop in March. For those already invested into Costco they're sitting pretty! But what about investors that want to start a position? Is now the time, or are there dips in the future that'll be better?
