iShares S&P GSCI Commodity-Indexed Trust (GSG) stock intrinsic value fair value estimate & owner earnings analysis

The iShares S&P GSCI Commodity-Indexed Trust is not an operating business. It is an investment trust sponsored by BlackRock that holds exchange-traded futures contracts on the S&P GSCI Excess Return Index, a basket of commodity futures weighted by world production. It holds the cash backing those positions mostly in U.S. Treasury bills. It sells no products, has no customers in the usual sense and has no earnings of its own. Each share is a claim on the trust's net assets: the futures positions plus the Treasury bills, minus accrued fees. Earnings-based measures such as owner earnings or free cash flow mean nothing here. The trust's reported operating cash flow swings with share creations and redemptions, not with any business performance, so we value the shares from net assets instead. What a share is worth. On June 30, 2026, the latest balance sheet date, net assets were $28.50 per share. That is up from $23.09 at December 31, 2025, and it moved sharply within the half-year: +39.6% in the first quarter and -11.6% in the second. Net asset value (NAV) changes every trading day with commodity futures prices, and we do not forecast those prices. Our estimates below are best read as percentages of the current NAV: roughly 88% (bear), 94% (base) and 97% (bull). They are not a forecast of where the shares will trade. The wrapper costs something. The trust pays BlackRock a fee of 0.75% a year on net assets, the maximum its trust agreement allows without an amendment and 30 days' notice. It also pays brokerage commissions. Total expenses were 0.82% to 0.83% of average net assets in each of 2023, 2024 and 2025, and about 0.80% annualized in the first half of 2026. An investor who owned the futures and Treasury bills directly would not pay this, so we treat the present value of these expenses, discounted at 6%, as the deduction from NAV. Interest on the Treasury bills (net investment income of 3.38% of net assets in 2025, 4.39% in 2024 and about 2.9% annualized in early 2026) passes through to NAV. It is simply the return on the cash collateral, and we treat it as neither a gain nor a loss against NAV. The cases. - Base ($26.84): the trust's own expense rate of 0.82% continues over a 10-year holding period, and at the end the shares are worth NAV. This takes about 5.8% off today's NAV. It assumes the market price stays close to NAV. The filings support that: in 2025, authorized participants created 356 baskets of 50,000 shares and redeemed 309, so there is a working arbitrage that keeps the price near NAV. - Bear ($25.04): the fee never ends. An investor who holds indefinitely bears the 0.83% expense rate forever, and its present value takes about 12% off NAV. - Bull ($27.53): the same expense rate is borne for only 5 years, for example because a discount to NAV closes within that period. This takes about 3.4% off NAV. The spread between the cases is narrow because the costs of owning the trust are known and contractual. The real uncertainty in these shares is the commodity market itself, which is outside what we value. That includes roll yield, meaning the gain or loss from replacing expiring futures contracts with later ones. The trust's filings warn that some commodities in the index have historically been in contango, where later-dated contracts cost more than nearer ones, and that this can erode value even when spot prices are flat. The filings do not separate that effect from price changes. Over the trust's life, NAV per share has fallen from about $49.06 at its July 2006 launch to $28.50, even with Treasury bill interest included. That record combines price moves, roll costs and fees, and we cannot split it into those parts from the filings. We have not put a roll cost into any case because we cannot measure it from the filings. A holder of the shares bears that exposure in full, in either direction. The trust has no borrowings. The trust agreement would dissolve it if the shares were delisted from NYSE Arca and not relisted within five business days, or if 75% of shareholders voted to dissolve. We see no sign of either. If it were dissolved, shareholders would receive their share of net assets. Margin-of-safety price. A trust that tracks an index and trades near NAV cannot, on its own, produce a 20% annual return except through commodity price moves, which we do not value. The only return we can value is a discount to NAV that later closes. So the margin-of-safety price sits at a large discount: about 30% below the current NAV, which is $20.00 against the June 30, 2026 NAV of $28.50. If such a discount closed to our base value within about two years, the implied return would be roughly 16% to 34% a year, depending on timing. The arbitrage described above makes a discount this large rare in a trust with about $1 billion of net assets.
