“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 twenty year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Alexion Pharmaceuticals Inc. (NASD: ALXN) 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: 06/28/1999
$10,000

06/28/1999
$512,681

06/25/2019
End date: 06/25/2019
Start price/share: $2.44
End price/share: $125.15
Starting shares: 4,098.36
Ending shares: 4,098.36
Dividends reinvested/share: $0.00
Total return: 5,029.10%
Average annual return: 21.75%
Starting investment: $10,000.00
Ending investment: $512,681.59

As we can see, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 21.75%. This would have turned a $10K investment made 20 years ago into $512,681.59 today (as of 06/25/2019). On a total return basis, that’s a result of 5,029.10% (something to think about: how might ALXN shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Here’s one more great investment quote before you go:
