“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 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 decade-long holding period for an investor who was considering Idexx Laboratories, Inc. (NASD: IDXX) back in 2009, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 04/30/2009
$10,000

04/30/2009
$117,402

04/29/2019
End date: 04/29/2019
Start price/share: $19.65
End price/share: $230.68
Starting shares: 508.91
Ending shares: 508.91
Dividends reinvested/share: $0.00
Total return: 1,073.94%
Average annual return: 27.92%
Starting investment: $10,000.00
Ending investment: $117,402.54

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 27.92%. This would have turned a $10K investment made 10 years ago into $117,402.54 today (as of 04/29/2019). On a total return basis, that’s a result of 1,073.94% (something to think about: how might IDXX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
