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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a decade-long holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Consolidated Edison Inc (NYSE: ED) back in 2011, holding through to today.

Start date: 12/12/2011
$10,000

12/12/2011
$20,267

12/09/2021
End date: 12/09/2021
Start price/share: $58.82
End price/share: $81.68
Starting shares: 170.01
Ending shares: 248.20
Dividends reinvested/share: $26.79
Total return: 102.73%
Average annual return: 7.32%
Starting investment: $10,000.00
Ending investment: $20,267.80

The above analysis shows the decade-long investment result worked out well, with an annualized rate of return of 7.32%. This would have turned a $10K investment made 10 years ago into $20,267.80 today (as of 12/09/2021). On a total return basis, that’s a result of 102.73% (something to think about: how might ED shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Consolidated Edison Inc paid investors a total of $26.79/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 3.1/share, we calculate that ED has a current yield of approximately 3.80%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.1 against the original $58.82/share purchase price. This works out to a yield on cost of 6.46%.

One more piece of investment wisdom to leave you with:
