Chart of the Day: Top 10 Now, Not Then

Today’s Chart of the Day is from Mike Zaccardi @MikeZaccardi and shows the ten largest companies in the S&P in 10-year spans for the last 40 years starting in 1985. 

Our memories can be short, and we often think that what is now has always been and will always continue. But from 20 years ago in 2005, the only company that is still in the top 10 is Microsoft. Just ten years ago, only four were. 

But of course, things change—new companies and industries emerge as others wane—and in fact, many of the top ten companies from 20 to 30 years ago significantly underperformed the overall market afterwards and are no longer anywhere near the top.
