“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 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: 12/06/1999
$10,000

12/06/1999
$248,659

12/05/2019
End date: 12/05/2019
Start price/share: $4.32
End price/share: $107.42
Starting shares: 2,314.81
Ending shares: 2,314.81
Dividends reinvested/share: $0.00
Total return: 2,386.57%
Average annual return: 17.42%
Starting investment: $10,000.00
Ending investment: $248,659.94

As shown above, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 17.42%. This would have turned a $10K investment made 20 years ago into $248,659.94 today (as of 12/05/2019). On a total return basis, that’s a result of 2,386.57% (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:
“The investor’s chief problem, even his worst enemy, is likely to be himself.” — Benjamin Graham
