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

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a ten year period?

Today, let’s look backwards in time to 2011, and take a look at what happened to investors who asked that very question about Regeneron Pharmaceuticals, Inc. (NASD: REGN), by taking a look at the investment outcome over a ten year holding period.

Start date: 01/21/2011


End date: 01/20/2021
Start price/share: $33.28
End price/share: $542.27
Starting shares: 300.48
Ending shares: 300.48
Dividends reinvested/share: $0.00
Total return: 1,529.42%
Average annual return: 32.17%
Starting investment: $10,000.00
Ending investment: $162,926.84

The above analysis shows the ten year investment result worked out exceptionally well, with an annualized rate of return of 32.17%. This would have turned a $10K investment made 10 years ago into $162,926.84 today (as of 01/20/2021). On a total return basis, that’s a result of 1,529.42% (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.]

One more investment quote to leave you with:
“If you’re looking for a home run, a great investment for five years or 10 years or more, then the only way to beat this enormous fog that covers the future is to identify a long-term trend that will give a particular business some sort of edge.” — Ralph Wanger
