“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 Mylan NV (NASD: MYL)? Today, we examine the outcome of a five year investment into the stock back in 2015.

Start date: 04/14/2015


End date: 04/13/2020
Start price/share: $68.62
End price/share: $16.06
Starting shares: 145.73
Ending shares: 145.73
Dividends reinvested/share: $0.00
Total return: -76.60%
Average annual return: -25.20%
Starting investment: $10,000.00
Ending investment: $2,339.71

As shown above, the five year investment result worked out poorly, with an annualized rate of return of -25.20%. This would have turned a $10K investment made 5 years ago into $2,339.71 today (as of 04/13/2020). On a total return basis, that’s a result of -76.60% (something to think about: how might MYL shares perform over the next 5 years?).
