“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a two-decade holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Carmax Inc. (NYSE: KMX) back in 1999. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 08/02/1999
$10,000

08/02/1999
$438,044

08/01/2019
End date: 08/01/2019
Start price/share: $1.97
End price/share: $86.30
Starting shares: 5,076.14
Ending shares: 5,076.14
Dividends reinvested/share: $0.00
Total return: 4,280.71%
Average annual return: 20.79%
Starting investment: $10,000.00
Ending investment: $438,044.87

As we can see, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 20.79%. This would have turned a $10K investment made 20 years ago into $438,044.87 today (as of 08/01/2019). On a total return basis, that’s a result of 4,280.71% (something to think about: how might KMX shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“The idea that a bell rings to signal when to get into or out of the stock market is simply not credible. After nearly fifty years in this business, I don’t know anybody who has done it successfully and consistently.” — Jack Bogle
