“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 DexCom Inc (NASD: DXCM)? Today, we examine the outcome of a five year investment into the stock back in 2016.

Start date: 10/31/2016
$10,000

10/31/2016
$72,887

10/28/2021
End date: 10/28/2021
Start price/share: $78.24
End price/share: $570.32
Starting shares: 127.81
Ending shares: 127.81
Dividends reinvested/share: $0.00
Total return: 628.94%
Average annual return: 48.84%
Starting investment: $10,000.00
Ending investment: $72,887.31

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 48.84%. This would have turned a $10K investment made 5 years ago into $72,887.31 today (as of 10/28/2021). On a total return basis, that’s a result of 628.94% (something to think about: how might DXCM shares perform over the next 5 years?).
