“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a decade-long holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Blackrock Inc (NYSE: BLK) back in 2012: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full decade-long investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 11/02/2012
$10,000

11/02/2012
  $44,246

11/01/2022
End date: 11/01/2022
Start price/share: $189.52
End price/share: $652.00
Starting shares: 52.76
Ending shares: 67.84
Dividends reinvested/share: $114.72
Total return: 342.33%
Average annual return: 16.03%
Starting investment: $10,000.00
Ending investment: $44,246.59

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 16.03%. This would have turned a $10K investment made 10 years ago into $44,246.59 today (as of 11/01/2022). On a total return basis, that’s a result of 342.33% (something to think about: how might BLK shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Blackrock Inc paid investors a total of $114.72/share in dividends over the 10 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 19.52/share, we calculate that BLK has a current yield of approximately 2.99%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 19.52 against the original $189.52/share purchase price. This works out to a yield on cost of 1.58%.
