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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a five year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Analog Devices Inc (NASD: ADI) back in 2019, holding through to today.

Start date: 05/08/2019
$10,000

05/08/2019
  $20,252

05/07/2024
End date: 05/07/2024
Start price/share: $110.55
End price/share: $203.57
Starting shares: 90.46
Ending shares: 99.47
Dividends reinvested/share: $14.26
Total return: 102.49%
Average annual return: 15.15%
Starting investment: $10,000.00
Ending investment: $20,252.92

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 15.15%. This would have turned a $10K investment made 5 years ago into $20,252.92 today (as of 05/07/2024). On a total return basis, that’s a result of 102.49% (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.]

Always an important consideration with a dividend-paying company is: should we reinvest our dividends?Over the past 5 years, Analog Devices Inc has paid $14.26/share in dividends. For the above analysis, we assume that the investor reinvests dividends into new shares of stock (for the above calculations, the reinvestment is performed using closing price on ex-div date for that dividend).

Based upon the most recent annualized dividend rate of 3.68/share, we calculate that ADI has a current yield of approximately 1.81%. 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 $110.55/share purchase price. This works out to a yield on cost of 1.64%.

More investment wisdom to ponder:
“The individual investor should act consistently as an investor and not as a speculator. This means that he should be able to justify every purchase he makes and each price he pays by impersonal, objective reasoning that satisfies him that he is getting more than his money’s worth for his purchase.” — Benjamin Graham
