“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 decade-long 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 decade-long investment into the stock back in 2010.

Start date: 08/09/2010


End date: 08/06/2020
Start price/share: $18.10
End price/share: $16.42
Starting shares: 552.49
Ending shares: 552.49
Dividends reinvested/share: $0.00
Total return: -9.28%
Average annual return: -0.97%
Starting investment: $10,000.00
Ending investment: $9,071.26

As shown above, the decade-long investment result worked out poorly, with an annualized rate of return of -0.97%. This would have turned a $10K investment made 10 years ago into $9,071.26 today (as of 08/06/2020). On a total return basis, that’s a result of -9.28% (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.]

One more piece of investment wisdom to leave you with:
