“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 twenty year 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 twenty year investment into the stock back in 2004.

Start date: 09/07/2004
$10,000

09/07/2004
  $102,707

09/03/2024
End date: 09/03/2024
Start price/share: $33.78
End price/share: $218.71
Starting shares: 296.03
Ending shares: 469.32
Dividends reinvested/share: $32.83
Total return: 926.46%
Average annual return: 12.35%
Starting investment: $10,000.00
Ending investment: $102,707.01

As we can see, the twenty year investment result worked out quite well, with an annualized rate of return of 12.35%. This would have turned a $10K investment made 20 years ago into $102,707.01 today (as of 09/03/2024). On a total return basis, that’s a result of 926.46% (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 $32.83/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 3.68/share, we calculate that ADI has a current yield of approximately 1.68%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.68 against the original $33.78/share purchase price. This works out to a yield on cost of 4.97%.

One more piece of investment wisdom to leave you with:
