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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a five year holding period for an investor who was considering Illumina Inc (NASD: ILMN) back in 2016, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 10/04/2016
$10,000

10/04/2016
$21,784

10/01/2021
End date: 10/01/2021
Start price/share: $181.22
End price/share: $394.84
Starting shares: 55.18
Ending shares: 55.18
Dividends reinvested/share: $0.00
Total return: 117.88%
Average annual return: 16.87%
Starting investment: $10,000.00
Ending investment: $21,784.33

The above analysis shows the five year investment result worked out exceptionally well, with an annualized rate of return of 16.87%. This would have turned a $10K investment made 5 years ago into $21,784.33 today (as of 10/01/2021). On a total return basis, that’s a result of 117.88% (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.]
