“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 ten year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Intuitive Surgical Inc (NASD: ISRG) back in 2010. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 04/07/2010
$10,000

04/07/2010
$45,033

04/06/2020
End date: 04/06/2020
Start price/share: $111.12
End price/share: $500.24
Starting shares: 89.99
Ending shares: 89.99
Dividends reinvested/share: $0.00
Total return: 350.18%
Average annual return: 16.23%
Starting investment: $10,000.00
Ending investment: $45,033.98

The above analysis shows the ten year investment result worked out exceptionally well, with an annualized rate of return of 16.23%. This would have turned a $10K investment made 10 years ago into $45,033.98 today (as of 04/06/2020). On a total return basis, that’s a result of 350.18% (something to think about: how might ISRG shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more investment quote to leave you with:
“You don’t need to be a rocket scientist. Investing is not a game where the guy with the 160 IQ beats the guy with 130 IQ.” — Warren Buffett
