“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 Edison International (NYSE: EIX) back in 2003: 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: 10/13/2003


End date: 10/11/2023
Start price/share: $19.71
End price/share: $64.93
Starting shares: 507.36
Ending shares: 983.29
Dividends reinvested/share: $34.70
Total return: 538.45%
Average annual return: 9.71%
Starting investment: $10,000.00
Ending investment: $63,863.85

The above analysis shows the two-decade investment result worked out well, with an annualized rate of return of 9.71%. This would have turned a $10K investment made 20 years ago into $63,863.85 today (as of 10/11/2023). On a total return basis, that’s a result of 538.45% (something to think about: how might EIX shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Beyond share price change, another component of EIX’s total return these past 20 years has been the payment by Edison International of $34.70/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of 2.95/share, we calculate that EIX has a current yield of approximately 4.54%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.95 against the original $19.71/share purchase price. This works out to a yield on cost of 23.03%.
