“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 decade-long 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 Illumina Inc (NASD: ILMN), by taking a look at the investment outcome over a decade-long holding period.

Start date: 01/11/2011


End date: 01/08/2021
Start price/share: $67.34
End price/share: $379.61
Starting shares: 148.50
Ending shares: 148.50
Dividends reinvested/share: $0.00
Total return: 463.72%
Average annual return: 18.88%
Starting investment: $10,000.00
Ending investment: $56,375.18

As we can see, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 18.88%. This would have turned a $10K investment made 10 years ago into $56,375.18 today (as of 01/08/2021). On a total return basis, that’s a result of 463.72% (something to think about: how might ILMN shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
“Experience taught me a few things. One is to listen to your gut, no matter how good something sounds on paper. The second is that you’re generally better off sticking with what you know. And the third is that sometimes your best investments are the ones you don’t make.” — Donald Trump
