Attached are the simplest fundamentals for Costco (COST) - Sales and Earnings per Share. Both are showing that COST is moving up significantly in their trends.
By just about every metric I look at for COST, they are improving significantly. This is the type of company I love to own.
My best investment returns are always on stocks that I bought several years before they blossomed. They were also out of favor or unrecognized at the time of the purchase. Ross Stores was that way in the early 1990's. Nvidia, Costco and Applied Materials were like that in the 2010 time frame.
