I guess I need to study Google Finance some more. All I did was, I added in a comparison to the S&P, and Costco jumped to 54,628% and Amazon to 164,805%. I'm sure there's some logical explanation for this.
Anyhow, I don't know anyone who works for Costco. Do you?
I'd call it a value stock. I invested a while ago specifically after having realized how good the foundations of that company are. How happy the customers are, how happy are the employees and how great PR they have.
The most surprising is how Kirkland clothing had been picked-up by the street wear communities. From my observation, this only really happens to "good" companies that we, the older generation, would thought of boring.
Some companies are good to invest in. Some are good to be a customer of. Some are good to work for. But very few companies are all three.
Amazon's definitely not the last of those three.
