“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 2013, 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 decade-long holding period.
| Start date: | 07/22/2013 |
|
|||
| End date: | 07/20/2023 | ||||
| Start price/share: | $108.95 | ||||
| End price/share: | $233.23 | ||||
| Starting shares: | 91.79 | ||||
| Ending shares: | 119.84 | ||||
| Dividends reinvested/share: | $51.68 | ||||
| Total return: | 179.49% | ||||
| Average annual return: | 10.82% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $27,937.11 | ||||
As we can see, the decade-long investment result worked out quite well, with an annualized rate of return of 10.82%. This would have turned a $10K investment made 10 years ago into $27,937.11 today (as of 07/20/2023). On a total return basis, that’s a result of 179.49% (something to think about: how might AMGN shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Amgen Inc paid investors a total of $51.68/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 8.52/share, we calculate that AMGN has a current yield of approximately 3.65%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 8.52 against the original $108.95/share purchase price. This works out to a yield on cost of 3.35%.
