“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 Intuitive Surgical Inc (NASD: ISRG) back in 2014. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 07/24/2014
$10,000

07/24/2014
  $86,532

07/23/2024
End date: 07/23/2024
Start price/share: $52.59
End price/share: $455.06
Starting shares: 190.15
Ending shares: 190.15
Dividends reinvested/share: $0.00
Total return: 765.30%
Average annual return: 24.07%
Starting investment: $10,000.00
Ending investment: $86,532.86

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 24.07%. This would have turned a $10K investment made 10 years ago into $86,532.86 today (as of 07/23/2024). On a total return basis, that’s a result of 765.30% (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:
“If you are not willing to own a stock for 10 years, do not even think about owning it for 10 minutes.” — Warren Buffett
