“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a five year holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 5 years to 2014, investors considering an investment into shares of Illumina Inc (NASD: ILMN) may have been pondering this very question and thinking about their potential investment result over a full five year time horizon. Here’s how that would have worked out.

Start date: 06/02/2014
$10,000

06/02/2014
$19,614

05/30/2019
End date: 05/30/2019
Start price/share: $158.68
End price/share: $311.20
Starting shares: 63.02
Ending shares: 63.02
Dividends reinvested/share: $0.00
Total return: 96.12%
Average annual return: 14.44%
Starting investment: $10,000.00
Ending investment: $19,614.09

The above analysis shows the five year investment result worked out quite well, with an annualized rate of return of 14.44%. This would have turned a $10K investment made 5 years ago into $19,614.09 today (as of 05/30/2019). On a total return basis, that’s a result of 96.12% (something to think about: how might ILMN shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
