“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a two-decade holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Analog Devices Inc (NASD: ADI)? Today, we examine the outcome of a two-decade investment into the stock back in 2002.

Start date: 10/31/2002
$10,000

10/31/2002
  $83,003

10/28/2022
End date: 10/28/2022
Start price/share: $26.80
End price/share: $144.88
Starting shares: 373.13
Ending shares: 573.09
Dividends reinvested/share: $26.07
Total return: 730.30%
Average annual return: 11.16%
Starting investment: $10,000.00
Ending investment: $83,003.55

As we can see, the two-decade investment result worked out quite well, with an annualized rate of return of 11.16%. This would have turned a $10K investment made 20 years ago into $83,003.55 today (as of 10/28/2022). On a total return basis, that’s a result of 730.30% (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 $26.07/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 3.04/share, we calculate that ADI has a current yield of approximately 2.10%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.04 against the original $26.80/share purchase price. This works out to a yield on cost of 7.84%.
