“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 Charles River Laboratories International Inc. (NYSE: CRL) back in 2011. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 12/12/2011
$10,000

12/12/2011
$131,321

12/09/2021
End date: 12/09/2021
Start price/share: $27.19
End price/share: $357.05
Starting shares: 367.78
Ending shares: 367.78
Dividends reinvested/share: $0.00
Total return: 1,213.17%
Average annual return: 29.37%
Starting investment: $10,000.00
Ending investment: $131,321.48

As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 29.37%. This would have turned a $10K investment made 10 years ago into $131,321.48 today (as of 12/09/2021). On a total return basis, that’s a result of 1,213.17% (something to think about: how might CRL shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
