“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 Biogen Inc (NASD: BIIB)? Today, we examine the outcome of a five year investment into the stock back in 2014.

Start date: 07/03/2014
$10,000

07/03/2014
$7,138

07/02/2019
End date: 07/02/2019
Start price/share: $331.15
End price/share: $236.37
Starting shares: 30.20
Ending shares: 30.20
Dividends reinvested/share: $0.00
Total return: -28.62%
Average annual return: -6.52%
Starting investment: $10,000.00
Ending investment: $7,138.28

As we can see, the five year investment result worked out poorly, with an annualized rate of return of -6.52%. This would have turned a $10K investment made 5 years ago into $7,138.28 today (as of 07/02/2019). On a total return basis, that’s a result of -28.62% (something to think about: how might BIIB shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
