“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 2015.

Start date: 04/01/2015
$10,000

04/01/2015
$5,296

03/31/2020
End date: 03/31/2020
Start price/share: $169.50
End price/share: $89.79
Starting shares: 59.00
Ending shares: 59.00
Dividends reinvested/share: $0.00
Total return: -47.03%
Average annual return: -11.93%
Starting investment: $10,000.00
Ending investment: $5,296.50

The above analysis shows the five year investment result worked out poorly, with an annualized rate of return of -11.93%. This would have turned a $10K investment made 5 years ago into $5,296.50 today (as of 03/31/2020). On a total return basis, that’s a result of -47.03% (something to think about: how might ALXN shares perform over the next 5 years?).
