“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 Interpublic Group of Companies Inc. (NYSE: IPG) back in 2009: 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: 06/18/2009
$10,000

06/18/2009
$51,306

06/17/2019
End date: 06/17/2019
Start price/share: $5.36
End price/share: $21.97
Starting shares: 1,865.67
Ending shares: 2,335.12
Dividends reinvested/share: $4.27
Total return: 413.03%
Average annual return: 17.76%
Starting investment: $10,000.00
Ending investment: $51,306.51

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 17.76%. This would have turned a $10K investment made 10 years ago into $51,306.51 today (as of 06/17/2019). On a total return basis, that’s a result of 413.03% (something to think about: how might IPG shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Interpublic Group of Companies Inc. paid investors a total of $4.27/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 .94/share, we calculate that IPG has a current yield of approximately 4.28%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .94 against the original $5.36/share purchase price. This works out to a yield on cost of 79.85%.

Another great investment quote to think about:
