“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”
— Warren Buffett
This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a ten year holding period potentially?
For “buyandhold” investors taking a longterm view, what’s important isn’t the shortterm stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 10 years to 2009, investors considering an investment into shares of Equinix Inc (NASD: EQIX) may have been pondering this very question and thinking about their potential investment result over a full ten year time horizon. Here’s how that would have worked out.
Start date:  07/02/2009 


End date:  07/01/2019  
Start price/share:  $71.43  
End price/share:  $504.94  
Starting shares:  140.00  
Ending shares:  166.96  
Dividends reinvested/share:  $54.32  
Total return:  743.06%  
Average annual return:  23.75%  
Starting investment:  $10,000.00  
Ending investment:  $84,276.33 
As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 23.75%. This would have turned a $10K investment made 10 years ago into $84,276.33 today (as of 07/01/2019). On a total return basis, that’s a result of 743.06% (something to think about: how might EQIX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Equinix Inc paid investors a total of $54.32/share in dividends over the 10 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on exdate is used for the reinvestment of a given dividend).
Based upon the most recent annualized dividend rate of 9.84/share, we calculate that EQIX has a current yield of approximately 1.95%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 9.84 against the original $71.43/share purchase price. This works out to a yield on cost of 2.73%.
