“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 5 years to 2020, investors considering an investment into shares of Packaging Corp of America (NYSE: PKG) may have been pondering this very question and thinking about their potential investment result over a full five year time horizon. Here’s how that would have worked out.

Start date: 06/05/2020
$10,000

06/05/2020
  $20,386

06/04/2025
End date: 06/04/2025
Start price/share: $110.56
End price/share: $193.34
Starting shares: 90.45
Ending shares: 105.44
Dividends reinvested/share: $22.58
Total return: 103.85%
Average annual return: 15.31%
Starting investment: $10,000.00
Ending investment: $20,386.13

The above analysis shows the five year investment result worked out exceptionally well, with an annualized rate of return of 15.31%. This would have turned a $10K investment made 5 years ago into $20,386.13 today (as of 06/04/2025). On a total return basis, that’s a result of 103.85% (something to think about: how might PKG shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Packaging Corp of America paid investors a total of $22.58/share in dividends over the 5 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 5/share, we calculate that PKG has a current yield of approximately 2.59%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 5 against the original $110.56/share purchase price. This works out to a yield on cost of 2.34%.
