“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a twenty year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Regeneron Pharmaceuticals, Inc. (NASD: REGN) back in 1999, holding through to today.

Start date: 12/13/1999


End date: 12/12/2019
Start price/share: $9.06
End price/share: $372.16
Starting shares: 1,103.45
Ending shares: 1,103.45
Dividends reinvested/share: $0.00
Total return: 4,006.59%
Average annual return: 20.40%
Starting investment: $10,000.00
Ending investment: $410,594.68

As we can see, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 20.40%. This would have turned a $10K investment made 20 years ago into $410,594.68 today (as of 12/12/2019). On a total return basis, that’s a result of 4,006.59% (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.]

Here’s one more great investment quote before you go:
“I learned early that there is nothing new in Wall Street. There can’t be because speculation is as old as the hills. Whatever happens in the stock market today has happened before and will happen again. I’ve never forgotten that.” — Jesse Livermore
