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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a five year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Biogen Inc (NASD: BIIB) back in 2014, holding through to today.

Start date: 05/23/2014
$10,000

05/23/2014
$7,844

05/22/2019
End date: 05/22/2019
Start price/share: $299.71
End price/share: $235.04
Starting shares: 33.37
Ending shares: 33.37
Dividends reinvested/share: $0.00
Total return: -21.58%
Average annual return: -4.74%
Starting investment: $10,000.00
Ending investment: $7,844.28

As shown above, the five year investment result worked out poorly, with an annualized rate of return of -4.74%. This would have turned a $10K investment made 5 years ago into $7,844.28 today (as of 05/22/2019). On a total return basis, that’s a result of -21.58% (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.]

Another great investment quote to think about:
“Most investors want to do today what they should have done yesterday.” — Larry Summers
