“I buy on the assumption that they could close the market the next day and not reopen it for five years.”
— Warren Buffett
A five-year holding period can be a useful lens for evaluating a regulated utility such as Alliant Energy Corp, where a meaningful share of long-term return often comes from dividends rather than rapid price appreciation. For an investor who purchased Alliant Energy Corp (NASD: LNT) in September 2021 and held the position through September 2026, the result was a positive total return, supported by both modest share-price gains and the compounding effect of reinvested dividends.
This kind of analysis is especially relevant for income-oriented equities. Utilities typically operate with relatively stable cash flows, regulated rate structures, and dividend policies that can make reinvestment an important contributor to shareholder returns over time. In Alliant Energy’s case, that dynamic is clearly visible in the five-year outcome.

A $10,000 investment in Alliant Energy on 09/16/2021 would have grown to $13,225.19 by 09/15/2026, assuming dividends were reinvested. That equates to a 32.27% total return and an average annual return of 5.75%. [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
What Drove the Return?
The result came from two sources:
- Share-price appreciation: the stock rose from $58.65 to $65.99.
- Dividend income: Alliant Energy paid $9.48 per share over the period, and reinvestment increased the share count from 170.50 to 200.44.
That distinction matters. The stock price alone did not produce the full investment outcome. Reinvestment added nearly 30 shares over five years, illustrating how total return for utility stocks can differ materially from price return.
Why Dividend Reinvestment Matters for Utility Stocks
Utilities are often evaluated for income, stability, and capital preservation characteristics, but the long-run math is driven by reinvestment discipline. In this example, dividends were assumed to be reinvested at the closing price on each ex-dividend date. That approach compounds income into additional shares, which then generate their own future dividends.
For slower-growing sectors, this mechanism can account for a substantial portion of cumulative return. It also helps explain why a stock with only moderate price appreciation can still deliver an acceptable multi-year result.
Current Yield and Yield on Cost
Based on the most recent annualized dividend rate of $2.14 per share, LNT has a current yield of approximately 3.24% using the ending share price of $65.99.
Another useful measure is yield on cost, which compares the current annualized dividend to the original purchase price. Using the 2021 entry price of $58.65, the current dividend rate implies a yield on cost of approximately 3.65%.
Yield on cost does not measure current market opportunity, but it does help show how the income stream on an original investment changes over time as the dividend grows. For long-term holders of dividend-paying equities, that can be a meaningful part of the investment case.
Key Takeaways
- Alliant Energy delivered a positive five-year total return from 2021 to 2026.
- Dividend reinvestment materially improved the outcome by increasing the share count.
- The investment profile was consistent with a regulated utility: moderate capital appreciation, steady income, and compounding through dividends.
- For LNT, total return analysis is more informative than stock-price change alone.
One final investment observation is worth keeping in mind: durable results often come less from short-term price movements than from the combination of time, cash distributions, and disciplined holding periods.
