“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

A critical pearl of wisdom from Warren Buffett teaches us that with any potential stock investment we may make, as soon as our buy order is filled we will have a choice: to remain a co-owner of that company for the long haul, or to react to the inevitable short-term ups and downs that the stock market is famous for (sometimes sharp ups and downs).

The reality of this choice forces us to challenge our confidence in any given company we might invest into, and keep our eyes on the long-term time horizon. The market may go up and down the interim, but over a twenty year holding period, will the investment succeed?

Back in 2001, investors may have been asking themselves that very question about Alliant Energy Corp (NASD: LNT). Let’s examine what would have happened over a twenty year holding period, had you invested in LNT shares back in 2001 and held on.

Start date: 07/16/2001


End date: 07/14/2021
Start price/share: $14.63
End price/share: $57.23
Starting shares: 683.53
Ending shares: 1,563.96
Dividends reinvested/share: $18.82
Total return: 795.05%
Average annual return: 11.58%
Starting investment: $10,000.00
Ending investment: $89,560.86

As shown above, the twenty year investment result worked out quite well, with an annualized rate of return of 11.58%. This would have turned a $10K investment made 20 years ago into $89,560.86 today (as of 07/14/2021). On a total return basis, that’s a result of 795.05% (something to think about: how might LNT shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Dividends are always an important investment factor to consider, and Alliant Energy Corp has paid $18.82/share in dividends to shareholders over the past 20 years we looked at above. Many an investor will only invest in stocks that pay dividends, so this component of total return is always an important consideration. Automated reinvestment of dividends into additional shares of stock can be a great way for an investor to compound their returns. The above calculations are done with the assuption that dividends received over time are reinvested (the calcuations use the closing price on ex-date).

Based upon the most recent annualized dividend rate of 1.61/share, we calculate that LNT has a current yield of approximately 2.81%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.61 against the original $14.63/share purchase price. This works out to a yield on cost of 19.21%.
