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

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a twenty year period?

Today, let’s look backwards in time to 2005, and take a look at what happened to investors who asked that very question about AT&T Inc (NYSE: T), by taking a look at the investment outcome over a twenty year holding period.

Start date: 03/21/2005
$10,000

03/21/2005
  $47,412

03/19/2025
End date: 03/19/2025
Start price/share: $17.53
End price/share: $26.84
Starting shares: 570.45
Ending shares: 1,765.28
Dividends reinvested/share: $26.18
Total return: 373.80%
Average annual return: 8.09%
Starting investment: $10,000.00
Ending investment: $47,412.78

As we can see, the twenty year investment result worked out well, with an annualized rate of return of 8.09%. This would have turned a $10K investment made 20 years ago into $47,412.78 today (as of 03/19/2025). On a total return basis, that’s a result of 373.80% (something to think about: how might T shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that AT&T Inc paid investors a total of $26.18/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 1.11/share, we calculate that T has a current yield of approximately 4.14%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.11 against the original $17.53/share purchase price. This works out to a yield on cost of 23.62%.
