American Financial Group heads into its third-quarter report with an unusual mix of tailwinds: a one-time real estate gain that management pulled forward into this quarter, accelerating premium growth, and a recovery in investment returns. The harder question is how much of the expected earnings jump comes from the property sale and how much from the insurance business itself. With the stock up while the broader market slipped, investors will want an answer that holds up once the gain is set aside.

Wall Street expects earnings of $3.50 per share on revenue of about $2.45 billion. That would be roughly 30% EPS growth from the $2.69 earned a year ago, on revenue growth of about 5%. The gap between those two growth rates stands out. Last quarter, management said the sale of the Charleston Harbor Resort & Marina should close in the third quarter and produce a pre-tax gain of about $125 million, or $1.20 per share, split equally between the property and casualty unit and the parent. Management reaffirmed its full-year plan and described the gain as upside to it, which suggests at least part of that benefit is built into the $3.50 estimate. If the sale closed on schedule, a headline beat may say little about operations. If it slipped, the quarter could look like a miss even if the underwriting results were healthy.

The operating story is what will decide whether the stock's recent strength is deserved. In the second quarter, net written premiums grew 6%, up from 3% in the first quarter and flat for all of 2025. About three-quarters of the company's 36 businesses grew. Renewal pricing including workers' comp firmed to about 4%. Property and transportation stood out, with a 90.3 combined ratio and renewal rates accelerating to 8%. Commercial auto liability, long a problem line, posted a small underwriting profit for a second straight quarter on 15% rate increases. Management said its casualty lines exposed to social inflation are through their reset. It also said a drag from a lender-placed quota share arrangement has ended, and it now wants to play offense in excess liability, umbrella and nonprofit coverage. Premium growth holding at mid-single digits or better, with another profitable quarter in commercial auto, would support that more aggressive stance.

The soft spots deserve equal attention. Workers' comp pricing fell about 2% in the second quarter, and specialty financial renewal rates turned slightly negative. Underlying loss ratios rose in specialty casualty and specialty financial, partly because management chose to reserve conservatively for social inflation. Competition from MGA and fronting capital in longer-tail casualty is a growing pressure, and California comp remains unprofitable. If price declines spread or loss ratios keep rising, the story shifts from disciplined growth to growth bought with margin.

Investment income is the other swing factor. Net investment income hit a second-quarter record, up 23%, and alternative investments returned 7.1% after a slightly negative first quarter. Management itself called its 8% full-year alternatives assumption aggressive, so another quarter near that level would help offset the weak start to the year.

Sentiment has warmed noticeably, with bearish readings easing from 27.5% to 9.8%. The stock has gained 4.2% since the last report against a 2.1% decline in the S&P 500. At $150.62 it trades well above its 200-day average and within about 3% of its post-earnings high of $154.99, close enough to be testing a breakout. That raises the bar somewhat. The real test is whether core underwriting margins and premium momentum stay intact once the Charleston gain is stripped out. If they do, the improving narrative from last quarter holds. If softer pricing is starting to show up in loss ratios, the gain will be doing too much of the work.
