“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a five year holding period for an investor who was considering Analog Devices Inc (NASD: ADI) back in 2017, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 01/25/2017
$10,000

01/25/2017
$23,923

01/24/2022
End date: 01/24/2022
Start price/share: $74.54
End price/share: $161.44
Starting shares: 134.16
Ending shares: 148.20
Dividends reinvested/share: $11.12
Total return: 139.25%
Average annual return: 19.06%
Starting investment: $10,000.00
Ending investment: $23,923.76

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 19.06%. This would have turned a $10K investment made 5 years ago into $23,923.76 today (as of 01/24/2022). On a total return basis, that’s a result of 139.25% (something to think about: how might ADI shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Analog Devices Inc paid investors a total of $11.12/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 2.76/share, we calculate that ADI has a current yield of approximately 1.71%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.76 against the original $74.54/share purchase price. This works out to a yield on cost of 2.29%.

Another great investment quote to think about:
