“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 two-decade period?

Today, let’s look backwards in time to 2003, and take a look at what happened to investors who asked that very question about Blackrock Inc (NYSE: BLK), by taking a look at the investment outcome over a two-decade holding period.

Start date: 03/27/2003
$10,000

03/27/2003
  $231,947

03/24/2023
End date: 03/24/2023
Start price/share: $43.57
End price/share: $644.88
Starting shares: 229.52
Ending shares: 359.54
Dividends reinvested/share: $151.80
Total return: 2,218.60%
Average annual return: 17.02%
Starting investment: $10,000.00
Ending investment: $231,947.07

The above analysis shows the two-decade investment result worked out exceptionally well, with an annualized rate of return of 17.02%. This would have turned a $10K investment made 20 years ago into $231,947.07 today (as of 03/24/2023). On a total return basis, that’s a result of 2,218.60% (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 $151.80/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 3.10%. 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 $43.57/share purchase price. This works out to a yield on cost of 7.11%.
