DMAX is a BlackRock exchange traded fund, a defined outcome wrapper around the iShares Core S&P 500 ETF, that launched in late 2024. It carries an expense ratio of 0.50 percent, more than sixteen times the charge of the very underlying it holds. The fund holds about $136 million in assets and trades near its NAV, a discount that is within the normal range for a liquid exchange traded fund. It has returned a modest single digit percentage year to date, a gain in a market that has risen strongly. From early 2025 through September 2026, the share price rose by a double digit margin. The S&P 500 index rose roughly twice that over the same span, a gap that is the single most important fact about the fund and the product working as designed, not a malfunction.
The defined outcome structure explains the gap and defines the debate. DMAX buys a protective put on the S&P 500 and sells a covered call through an annual reset date in late December, capping upside at a level set at launch and buffering a defined share of a one year loss. The cost of that structure, the 0.50 percent fee plus the embedded options premium, is a real and recurring drag that the index does not pay. The central question is whether an investor would accept a structurally capped, structurally buffered, roughly twofold underperforming share in exchange for a floor on a one year decline, and whether the floor is worth the premium once the reset date in December 2026 approaches and the protection expires for a new period. The answer depends almost entirely on the shape of the next twelve months in the S&P 500, a path no participant can know, and on whether the modest buffer compensates for the guaranteed give up of upside in a year that already produced a large gain in the index.
