“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Amgen Inc (NASD: AMGN) back in 2017. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 05/03/2017
$10,000

05/03/2017
$16,303

05/02/2022
End date: 05/02/2022
Start price/share: $163.81
End price/share: $230.92
Starting shares: 61.05
Ending shares: 70.60
Dividends reinvested/share: $29.91
Total return: 63.03%
Average annual return: 10.27%
Starting investment: $10,000.00
Ending investment: $16,303.73

As shown above, the five year investment result worked out quite well, with an annualized rate of return of 10.27%. This would have turned a $10K investment made 5 years ago into $16,303.73 today (as of 05/02/2022). On a total return basis, that’s a result of 63.03% (something to think about: how might AMGN shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of Amgen Inc, investors have received $29.91/share in dividends these past 5 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of 7.76/share, we calculate that AMGN has a current yield of approximately 3.36%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 7.76 against the original $163.81/share purchase price. This works out to a yield on cost of 2.05%.
