“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 two-decade holding period for an investor who was considering Alexion Pharmaceuticals Inc. (NASD: ALXN) back in 1999, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 04/05/1999
$10,000

04/05/1999
$647,959

04/03/2019
End date: 04/03/2019
Start price/share: $2.16
End price/share: $139.99
Starting shares: 4,629.63
Ending shares: 4,629.63
Dividends reinvested/share: $0.00
Total return: 6,381.02%
Average annual return: 23.18%
Starting investment: $10,000.00
Ending investment: $647,959.95

As shown above, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 23.18%. This would have turned a $10K investment made 20 years ago into $647,959.95 today (as of 04/03/2019). On a total return basis, that’s a result of 6,381.02% (something to think about: how might ALXN 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:
“There’s a virtuous cycle when people have to defend challenges to their ideas. Any gaps in thinking or analysis become clear pretty quickly when smart people ask good, logical questions.” — Joel Greenblatt
