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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a ten year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Alliant Energy Corp (NASD: LNT)? Today, we examine the outcome of a ten year investment into the stock back in 2013.

Start date: 05/31/2013
$10,000

05/31/2013
  $28,453

05/30/2023
End date: 05/30/2023
Start price/share: $24.63
End price/share: $51.01
Starting shares: 406.01
Ending shares: 557.92
Dividends reinvested/share: $13.54
Total return: 184.59%
Average annual return: 11.02%
Starting investment: $10,000.00
Ending investment: $28,453.56

The above analysis shows the ten year investment result worked out quite well, with an annualized rate of return of 11.02%. This would have turned a $10K investment made 10 years ago into $28,453.56 today (as of 05/30/2023). On a total return basis, that’s a result of 184.59% (something to think about: how might LNT shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Alliant Energy Corp paid investors a total of $13.54/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 1.81/share, we calculate that LNT has a current yield of approximately 3.55%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.81 against the original $24.63/share purchase price. This works out to a yield on cost of 14.41%.

Another great investment quote to think about:
“The best way to measure your investing success is not by whether you’re beating the market but by whether you’ve put in place a financial plan and a behavioral discipline that are likely to get you where you want to go.” — Benjamin Graham
