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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Vertex Pharmaceuticals, Inc. (NASD: VRTX)? Today, we examine the outcome of a decade-long investment into the stock back in 2010.

Start date: 01/19/2010
$10,000

01/19/2010
$56,179

01/15/2020
End date: 01/15/2020
Start price/share: $41.68
End price/share: $234.15
Starting shares: 239.92
Ending shares: 239.92
Dividends reinvested/share: $0.00
Total return: 461.78%
Average annual return: 18.85%
Starting investment: $10,000.00
Ending investment: $56,179.89

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 18.85%. This would have turned a $10K investment made 10 years ago into $56,179.89 today (as of 01/15/2020). On a total return basis, that’s a result of 461.78% (something to think about: how might VRTX shares perform over the next 10 years?).
