“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 two-decade holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into CMS Energy Corp (NYSE: CMS) back in 2004: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full two-decade investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 05/24/2004
$10,000

05/24/2004
  $134,714

05/22/2024
End date: 05/22/2024
Start price/share: $8.04
End price/share: $61.84
Starting shares: 1,243.78
Ending shares: 2,177.21
Dividends reinvested/share: $20.51
Total return: 1,246.39%
Average annual return: 13.88%
Starting investment: $10,000.00
Ending investment: $134,714.12

As we can see, the two-decade investment result worked out quite well, with an annualized rate of return of 13.88%. This would have turned a $10K investment made 20 years ago into $134,714.12 today (as of 05/22/2024). On a total return basis, that’s a result of 1,246.39% (something to think about: how might CMS shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that CMS Energy Corp paid investors a total of $20.51/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 2.06/share, we calculate that CMS has a current yield of approximately 3.33%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.06 against the original $8.04/share purchase price. This works out to a yield on cost of 41.42%.

Another great investment quote to think about:
“Smart investing doesn’t consist of buying good assets but of buying assets well. This is a very, very important distinction that very, very few people understand.” — Howard Marks
