“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 PPL Corp (NYSE: PPL) back in 2009: 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: 05/29/2009
$10,000

05/29/2009
$16,368

05/28/2019
End date: 05/28/2019
Start price/share: $30.24
End price/share: $30.58
Starting shares: 330.69
Ending shares: 535.44
Dividends reinvested/share: $14.30
Total return: 63.74%
Average annual return: 5.05%
Starting investment: $10,000.00
Ending investment: $16,368.89

As shown above, the decade-long investment result worked out well, with an annualized rate of return of 5.05%. This would have turned a $10K investment made 10 years ago into $16,368.89 today (as of 05/28/2019). On a total return basis, that’s a result of 63.74% (something to think about: how might PPL shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of PPL Corp, investors have received $14.30/share in dividends these past 10 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of 1.65/share, we calculate that PPL has a current yield of approximately 5.40%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.65 against the original $30.24/share purchase price. This works out to a yield on cost of 17.86%.

Here’s one more great investment quote before you go:
