“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a twenty 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 twenty year investment into the stock back in 1999.

Start date: 08/16/1999
$10,000

08/16/1999
$310,706

08/13/2019
End date: 08/13/2019
Start price/share: $9.81
End price/share: $304.86
Starting shares: 1,019.11
Ending shares: 1,019.11
Dividends reinvested/share: $0.00
Total return: 3,006.85%
Average annual return: 18.74%
Starting investment: $10,000.00
Ending investment: $310,706.00

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 18.74%. This would have turned a $10K investment made 20 years ago into $310,706.00 today (as of 08/13/2019). On a total return basis, that’s a result of 3,006.85% (something to think about: how might REGN shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
