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

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a decade-long holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Equinix Inc (NASD: EQIX) back in 2010: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full decade-long investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 01/11/2010
$10,000

01/11/2010
$65,266

01/08/2020
End date: 01/08/2020
Start price/share: $107.65
End price/share: $583.80
Starting shares: 92.89
Ending shares: 111.77
Dividends reinvested/share: $59.24
Total return: 552.50%
Average annual return: 20.64%
Starting investment: $10,000.00
Ending investment: $65,266.45

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 20.64%. This would have turned a $10K investment made 10 years ago into $65,266.45 today (as of 01/08/2020). On a total return basis, that’s a result of 552.50% (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 $59.24/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 ex-date 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 1.69%. 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 $107.65/share purchase price. This works out to a yield on cost of 1.57%.
