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

— 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 decade-long holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Align Technology Inc (NASD: ALGN) back in 2009. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 11/09/2009
$10,000

11/09/2009
$156,033

11/07/2019
End date: 11/07/2019
Start price/share: $16.60
End price/share: $258.94
Starting shares: 602.41
Ending shares: 602.41
Dividends reinvested/share: $0.00
Total return: 1,459.88%
Average annual return: 31.62%
Starting investment: $10,000.00
Ending investment: $156,033.86

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 31.62%. This would have turned a $10K investment made 10 years ago into $156,033.86 today (as of 11/07/2019). On a total return basis, that’s a result of 1,459.88% (something to think about: how might ALGN shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
