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

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a decade-long period?

Today, let’s look backwards in time to 2011, and take a look at what happened to investors who asked that very question about Interpublic Group of Companies Inc. (NYSE: IPG), by taking a look at the investment outcome over a decade-long holding period.

Start date: 08/29/2011


End date: 08/26/2021
Start price/share: $8.66
End price/share: $36.45
Starting shares: 1,154.73
Ending shares: 1,570.07
Dividends reinvested/share: $6.18
Total return: 472.29%
Average annual return: 19.06%
Starting investment: $10,000.00
Ending investment: $57,234.62

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 19.06%. This would have turned a $10K investment made 10 years ago into $57,234.62 today (as of 08/26/2021). On a total return basis, that’s a result of 472.29% (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 $6.18/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 1.08/share, we calculate that IPG has a current yield of approximately 2.96%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.08 against the original $8.66/share purchase price. This works out to a yield on cost of 34.18%.
