“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 Walgreens Boots Alliance Inc (NASD: WBA)? Today, we examine the outcome of a twenty year investment into the stock back in 2005.

Start date: 06/20/2005
$10,000

06/20/2005
  $4,300

06/17/2025
End date: 06/17/2025
Start price/share: $45.59
End price/share: $11.39
Starting shares: 219.35
Ending shares: 377.48
Dividends reinvested/share: $23.06
Total return: -57.00%
Average annual return: -4.13%
Starting investment: $10,000.00
Ending investment: $4,300.85

As we can see, the twenty year investment result worked out poorly, with an annualized rate of return of -4.13%. This would have turned a $10K investment made 20 years ago into $4,300.85 today (as of 06/17/2025). On a total return basis, that’s a result of -57.00% (something to think about: how might WBA shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Walgreens Boots Alliance Inc paid investors a total of $23.06/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/share, we calculate that WBA has a current yield of approximately 8.78%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1 against the original $45.59/share purchase price. This works out to a yield on cost of 19.26%.

Another great investment quote to think about:
“A lot of people with high IQs are terrible investors because they’ve got terrible temperaments. You need to keep raw, irrational emotion under control.” — Charlie Munger
