“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: 10/20/2014
$10,000

10/20/2014
$7,244

10/17/2019
End date: 10/17/2019
Start price/share: $311.41
End price/share: $225.60
Starting shares: 32.11
Ending shares: 32.11
Dividends reinvested/share: $0.00
Total return: -27.56%
Average annual return: -6.25%
Starting investment: $10,000.00
Ending investment: $7,244.53

As shown above, the five year investment result worked out poorly, with an annualized rate of return of -6.25%. This would have turned a $10K investment made 5 years ago into $7,244.53 today (as of 10/17/2019). On a total return basis, that’s a result of -27.56% (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.]
