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

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a ten year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Amgen Inc (NASD: AMGN) back in 2014. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 07/29/2014
$10,000

07/29/2014
  $35,886

07/26/2024
End date: 07/26/2024
Start price/share: $123.31
End price/share: $334.85
Starting shares: 81.10
Ending shares: 107.13
Dividends reinvested/share: $58.28
Total return: 258.72%
Average annual return: 13.63%
Starting investment: $10,000.00
Ending investment: $35,886.41

As shown above, the ten year investment result worked out quite well, with an annualized rate of return of 13.63%. This would have turned a $10K investment made 10 years ago into $35,886.41 today (as of 07/26/2024). On a total return basis, that’s a result of 258.72% (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 $58.28/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 9/share, we calculate that AMGN has a current yield of approximately 2.69%. 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 $123.31/share purchase price. This works out to a yield on cost of 2.18%.

One more investment quote to leave you with:
