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

— Warren Buffett

This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a decade-long holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 10 years to 2013, investors considering an investment into shares of Standard and Poors Global Inc (NYSE: SPGI) may have been pondering this very question and thinking about their potential investment result over a full decade-long time horizon. Here’s how that would have worked out.

Start date: 08/01/2013


End date: 07/31/2023
Start price/share: $62.61
End price/share: $394.51
Starting shares: 159.72
Ending shares: 178.50
Dividends reinvested/share: $21.32
Total return: 604.21%
Average annual return: 21.55%
Starting investment: $10,000.00
Ending investment: $70,433.92

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 21.55%. This would have turned a $10K investment made 10 years ago into $70,433.92 today (as of 07/31/2023). On a total return basis, that’s a result of 604.21% (something to think about: how might SPGI shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Standard and Poors Global Inc paid investors a total of $21.32/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 3.6/share, we calculate that SPGI has a current yield of approximately 0.91%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.6 against the original $62.61/share purchase price. This works out to a yield on cost of 1.45%.

Another great investment quote to think about:
“In trading you have to be defensive and aggressive at the same time. If you are not aggressive, you are not going to make money, and if you are not defensive, you are not going to keep money.” — Ray Dalio
