“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 Blackrock Inc (NYSE: BLK)? Today, we examine the outcome of a two-decade investment into the stock back in 2004.

Start date: 01/02/2004


End date: 12/29/2023
Start price/share: $53.99
End price/share: $811.80
Starting shares: 185.22
Ending shares: 293.96
Dividends reinvested/share: $166.40
Total return: 2,286.37%
Average annual return: 17.19%
Starting investment: $10,000.00
Ending investment: $238,781.03

As shown above, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 17.19%. This would have turned a $10K investment made 20 years ago into $238,781.03 today (as of 12/29/2023). On a total return basis, that’s a result of 2,286.37% (something to think about: how might BLK shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Blackrock Inc paid investors a total of $166.40/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 20/share, we calculate that BLK has a current yield of approximately 2.46%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 20 against the original $53.99/share purchase price. This works out to a yield on cost of 4.56%.
