“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 twenty year period?

Today, let’s look backwards in time to 2004, and take a look at what happened to investors who asked that very question about Amgen Inc (NASD: AMGN), by taking a look at the investment outcome over a twenty year holding period.

Start date: 07/12/2004
$10,000

07/12/2004
  $81,987

07/09/2024
End date: 07/09/2024
Start price/share: $53.98
End price/share: $315.91
Starting shares: 185.25
Ending shares: 259.38
Dividends reinvested/share: $63.38
Total return: 719.42%
Average annual return: 11.09%
Starting investment: $10,000.00
Ending investment: $81,987.87

As we can see, the twenty year investment result worked out quite well, with an annualized rate of return of 11.09%. This would have turned a $10K investment made 20 years ago into $81,987.87 today (as of 07/09/2024). On a total return basis, that’s a result of 719.42% (something to think about: how might AMGN shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Amgen Inc paid investors a total of $63.38/share in dividends over the 20 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/share, we calculate that AMGN has a current yield of approximately 2.85%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 9 against the original $53.98/share purchase price. This works out to a yield on cost of 5.28%.
