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

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a decade-long holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Vertex Pharmaceuticals, Inc. (NASD: VRTX) back in 2009: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full decade-long investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 12/10/2009
$10,000

12/10/2009
$54,440

12/09/2019
End date: 12/09/2019
Start price/share: $40.29
End price/share: $219.37
Starting shares: 248.20
Ending shares: 248.20
Dividends reinvested/share: $0.00
Total return: 444.48%
Average annual return: 18.46%
Starting investment: $10,000.00
Ending investment: $54,440.09

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 18.46%. This would have turned a $10K investment made 10 years ago into $54,440.09 today (as of 12/09/2019). On a total return basis, that’s a result of 444.48% (something to think about: how might VRTX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Here’s one more great investment quote before you go:
