“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 ten year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Regeneron Pharmaceuticals, Inc. (NASD: REGN)? Today, we examine the outcome of a ten year investment into the stock back in 2010.

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

10/04/2010
$200,916

10/01/2020
End date: 10/01/2020
Start price/share: $28.27
End price/share: $568.14
Starting shares: 353.73
Ending shares: 353.73
Dividends reinvested/share: $0.00
Total return: 1,909.69%
Average annual return: 34.99%
Starting investment: $10,000.00
Ending investment: $200,916.67

The above analysis shows the ten year investment result worked out exceptionally well, with an annualized rate of return of 34.99%. This would have turned a $10K investment made 10 years ago into $200,916.67 today (as of 10/01/2020). On a total return basis, that’s a result of 1,909.69% (something to think about: how might REGN shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
