“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a decade-long period?

Today, let’s look backwards in time to 2010, and take a look at what happened to investors who asked that very question about Carmax Inc. (NYSE: KMX), by taking a look at the investment outcome over a decade-long holding period.

Start date: 09/20/2010


End date: 09/17/2020
Start price/share: $23.89
End price/share: $102.99
Starting shares: 418.59
Ending shares: 418.59
Dividends reinvested/share: $0.00
Total return: 331.10%
Average annual return: 15.73%
Starting investment: $10,000.00
Ending investment: $43,098.24

As we can see, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 15.73%. This would have turned a $10K investment made 10 years ago into $43,098.24 today (as of 09/17/2020). On a total return basis, that’s a result of 331.10% (something to think about: how might KMX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“Financial peace isn’t the acquisition of stuff. It’s learning to live on less than you make, so you can give money back and have money to invest. You can’t win until you do this.” — Dave Ramsey
