“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 twenty year holding period for an investor who was considering Illumina Inc (NASD: ILMN) back in 2002, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 05/16/2002


End date: 05/13/2022
Start price/share: $3.26
End price/share: $233.56
Starting shares: 3,067.48
Ending shares: 3,067.48
Dividends reinvested/share: $0.00
Total return: 7,064.42%
Average annual return: 23.80%
Starting investment: $10,000.00
Ending investment: $716,013.07

As shown above, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 23.80%. This would have turned a $10K investment made 20 years ago into $716,013.07 today (as of 05/13/2022). On a total return basis, that’s a result of 7,064.42% (something to think about: how might ILMN shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“A 10% decline in the market is fairly common, it happens about once a year. Investors who realize this are less likely to sell in a panic, and more likely to remain invested, benefitting from the wealthbuilding power of stocks.” — Christopher Davis
