American International Group, Inc. (AIG) — Valuation Snapshot

American International Group, Inc. (AIG) is a bank, insurer or other financial, and a free-cash-flow discounted-cash-flow (DCF) model is structurally the wrong lens for it: for these businesses debt and float are raw material, not financing. So we value it the way a bank is valued — on the return it earns on its book equity. Our bank model (justified price-to-book) puts it at about $93.36 a share, between $76.68 and $119.32 for a cost of equity one point either side of 7.1%, against $79.63 today. Every input is listed with its source. It is a model estimate, not a price target, and not investment advice.

On the numbers we do have, AIG trades at a recent price of $79.63, a market capitalisation of about $41,283,284,992, sitting 52% of the way up its 52-week range ($71.25–$87.29), on the NYSE.

The standard alternative to a DCF is relative valuation — comparing AIG's trading multiples against its direct industry peers. Here that gives P/E of 13.0× (richer than the peer median of 11.5×); Fwd P/E of 9.1× (cheaper than the peer median of 12.3×); P/B of 1.1× (cheaper than the peer median of 2.8×); P/S of 1.5× (in line with the peer median of 1.4×); Dividend yield of 2.5% (cheaper than the peer median of 1.3%). A cheaper multiple than peers can flag a discount or a market that expects weaker growth; it is a comparison, not a recommendation.

The asset, or book-value, lens is the classic tool for asset-heavy businesses and financials. AIG shows a price-to-book (P/B) of 1.06 and book value of $74.96 per share. Price-to-book compares the market price to the accounting net-asset value per share; below 1.0 can mean a discount to net assets or that the market is pricing in trouble — descriptive either way, never a buy signal on its own.

Finally, a price-based read — explicitly not a valuation. AIG is in an up-trend (price above both its 50- and 200-day averages), trading -8.8% from its 52-week high. Over the past year the stock is +1.1%. Moving-average trend and 52-week position describe where the stock has traded; they say nothing about what it is worth.

To be exact about what this page is not: we are not saying the numbers for AIG are unavailable. They are, and they are above. We are saying a discounted-cash-flow model is the wrong instrument for this kind of business, and publishing one anyway — because the inputs happen to exist — would be a precise answer to the wrong question. Refusing is the more useful answer, and it is the same rule we apply to every name in this category.
