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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Alexion Pharmaceuticals Inc. (NASD: ALXN)? Today, we examine the outcome of a five year investment into the stock back in 2014.

Start date: 10/15/2014
$10,000

10/15/2014
$6,305

10/14/2019
End date: 10/14/2019
Start price/share: $160.73
End price/share: $101.34
Starting shares: 62.22
Ending shares: 62.22
Dividends reinvested/share: $0.00
Total return: -36.95%
Average annual return: -8.81%
Starting investment: $10,000.00
Ending investment: $6,305.74

As we can see, the five year investment result worked out poorly, with an annualized rate of return of -8.81%. This would have turned a $10K investment made 5 years ago into $6,305.74 today (as of 10/14/2019). On a total return basis, that’s a result of -36.95% (something to think about: how might ALXN shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“If you don’t study any companies, you have the same success buying stocks as you do in a poker game if you bet without looking at your cards.” — Peter Lynch
