“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 Eversource Energy (NYSE: ES) back in 2014: 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: 08/29/2014
$10,000

08/29/2014
  $20,200

08/28/2024
End date: 08/28/2024
Start price/share: $45.89
End price/share: $67.04
Starting shares: 217.91
Ending shares: 301.30
Dividends reinvested/share: $21.66
Total return: 101.99%
Average annual return: 7.28%
Starting investment: $10,000.00
Ending investment: $20,200.16

As we can see, the decade-long investment result worked out well, with an annualized rate of return of 7.28%. This would have turned a $10K investment made 10 years ago into $20,200.16 today (as of 08/28/2024). On a total return basis, that’s a result of 101.99% (something to think about: how might ES shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Eversource Energy paid investors a total of $21.66/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 2.86/share, we calculate that ES has a current yield of approximately 4.27%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.86 against the original $45.89/share purchase price. This works out to a yield on cost of 9.30%.

Another great investment quote to think about:
“You can’t be a good value investor without being an independent thinker; you’re seeing valuations that the market is not appreciating. But it’s critical that you understand why the market isn’t seeing the value you do.” — Joel Greenblatt
