“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 Align Technology Inc (NASD: ALGN) back in 2005. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 11/25/2005
$10,000

11/25/2005
$206,779

11/21/2025
End date: 11/21/2025
Start price/share: $6.90
End price/share: $142.56
Starting shares: 1,449.28
Ending shares: 1,449.28
Dividends reinvested/share: $0.00
Total return: 1,966.09%
Average annual return: 16.35%
Starting investment: $10,000.00
Ending investment: $206,779.72

As we can see, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 16.35%. This would have turned a $10K investment made 20 years ago into $206,779.72 today (as of 11/21/2025). On a total return basis, that’s a result of 1,966.09% (something to think about: how might ALGN shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
