AI summary

Alliant Energy's stock has traded near its 52-week low this week, with shares closing at $63.60 on September 28 after a 1.48% drop on September 23 and a flat, lower session on September 24. The company reported Q2 revenue up 1% to $971 million, beating estimates, though operating income fell 17% year over year, and it filed a Wisconsin application to establish a standard electric rate for large-load customers such as data centers. Several analysts, including Jefferies, BMO Capital and Mizuho, have lowered price targets, even as the company continues to point to data center demand, including a 370 MW Iowa agreement, as a growth driver.

The stock closed at $63.21, down 0.6%, sitting below both its 50-day average of $68.91 and 200-day average of $70.32, with the 50-day below the 200-day. Over the past month it is down 7.3%, and over three months down 18.1%. The GekkoIndex reads 77.4, placing it in the Buying zone, while the price sits 13.1% below the Gekko Fair Value of $72.71.

Over the next 20 trading days, the next earnings report is scheduled for 5 November, 37 days away, outside a typical holding window. No insider, Congress or unusual options activity appears in the current window. Seasonally, the next 20 trading days have averaged -0.6% over 5 years, rising in 2 of them.
