“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 two-decade holding period for an investor who was considering Analog Devices Inc (NASD: ADI) back in 1999, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 10/18/1999
$10,000

10/18/1999
$61,237

10/16/2019
End date: 10/16/2019
Start price/share: $26.22
End price/share: $110.59
Starting shares: 381.39
Ending shares: 553.61
Dividends reinvested/share: $18.01
Total return: 512.24%
Average annual return: 9.48%
Starting investment: $10,000.00
Ending investment: $61,237.73

The above analysis shows the two-decade investment result worked out well, with an annualized rate of return of 9.48%. This would have turned a $10K investment made 20 years ago into $61,237.73 today (as of 10/16/2019). On a total return basis, that’s a result of 512.24% (something to think about: how might ADI shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Analog Devices Inc paid investors a total of $18.01/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 2.16/share, we calculate that ADI has a current yield of approximately 1.95%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.16 against the original $26.22/share purchase price. This works out to a yield on cost of 7.44%.
