“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a ten 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 ten year investment into the stock back in 2010.

Start date: 09/09/2010


End date: 09/08/2020
Start price/share: $17.70
End price/share: $15.64
Starting shares: 564.97
Ending shares: 564.97
Dividends reinvested/share: $0.00
Total return: -11.64%
Average annual return: -1.23%
Starting investment: $10,000.00
Ending investment: $8,835.30

As shown above, the ten year investment result worked out poorly, with an annualized rate of return of -1.23%. This would have turned a $10K investment made 10 years ago into $8,835.30 today (as of 09/08/2020). On a total return basis, that’s a result of -11.64% (something to think about: how might MYL shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
