Start here: what IWMI actually is
IWMI is the NEOS Russell 2000 High Income ETF. Under the hood it holds the Russell 2000 — small-cap U.S. stocks, via the Vanguard Russell 2000 tracker (VTWO is 99.5% of assets) — and layers an actively managed Russell 2000 index call-writing strategy on top to manufacture monthly income. NEOS says the overlay may include both sold and purchased RUT calls; as of the fund's 2026-09-21 holdings file it held only short calls (two RUT 10/16/26 lines, strikes 3005 and 3050), so the spread is a permitted tool, not the current position. In plain terms: you own small caps, and the fund sells away part of their upside in exchange for cash it pays you every month.
That places it in a crowded corner of the market. Small-cap covered-call and options-income funds have multiplied over the last few years — Global X's RYLD and RYLG, iShares' IWMW, Liquid Strategies' OVS — each selling options against the same volatile asset class for income. (Cadence differs: OVS paid quarterly until January 2026, when it switched to monthly.) Small caps are the most rate-sensitive major sleeve of the U.S. market, and their volatility is exactly the raw material these funds sell. When rates fall and small caps run, these strategies have a lot to work with. That's the backdrop.
There is no stock-picking decision here to analyse. NEOS's own fact sheet (as of 2026-08-31) lists a single equity holding — the Vanguard Russell 2000 ETF, at 100.01% of the portfolio — against which the short RUT calls are written; the fund's daily holdings file puts it at 99.5% as of 2026-09-21. Whatever the Russell 2000's sector mix happens to be on a given day, that is IWMI's sector mix. The differentiation is entirely in the options overlay, not stock selection.
The skeptic's case, and why IWMI is a useful counter-example
Start with the result that ought to bother you. Over the common window these five funds share, IWMW paid out 41.0% of its starting price — more cash than any of the others — and finished last on total return at +30.89%. OVS paid out 16.1%, less than half as much, and finished second at +39.45%. If the size of the distribution were the thing that mattered, those two results would be reversed. They are not, and the three tests below are what actually explain the gap.
The standard critique of covered-call funds is that the trade is always the same: you give up the upside and, distribution by distribution, the share price melts. Sometimes that's exactly what happens. With IWMI, over its life so far, it didn't — the price finished roughly where it started while the fund paid out a third of its starting value in cash.
Here's the part worth internalizing: the reason it held up is not the yield. The yield can't tell you that. What tells you is a set of measurements almost nobody runs. So rather than sell you on IWMI, this piece hands you three tests you can run on any income fund you own — then works all three on IWMI and shows the same tests on funds where the answer comes back different.
The income, in real numbers
Lead with what you came for. IWMI pays monthly. The latest declared distribution was $0.6075 per share (declared 2026-09-15, ex-dividend 2026-09-16, paid 2026-09-18). At the current $50.00 price, annualizing that latest payout gives a run-rate of about 14.58%. The trailing-12-month distributions total $7.2575 per share (the twelve payments from October 2025 through September 2026), which works out to a 14.52% TTM distribution yield — the honest income figure, because it's what a holder actually received over a full year across changing conditions.
Distributions here are variable by design. The overlay's income depends on option premiums, which move with volatility, so month-to-month payouts change. Treat $0.6075 as the latest actual, not a fixed coupon.

Test 1 — Capture: did the fund keep what the index made?
The math is simple: divide the fund's total return by the underlying index's total return over the same window. IWMI's underlying is the Russell 2000, so the yardstick is IWM. Here's IWMI vs IWM across several windows:
| Window | IWMI total return | IWM total return | Capture |
| 6-month (from 2026-03-18) | +14.28% | +16.06% | 88.9% |
| Year-to-date (from 2025-12-31) | +14.39% | +16.19% | 88.9% |
| 1-year (from 2025-09-18) | +18.36% | +17.21% | 106.7% |
| 2-year (from 2024-09-18) | +32.32% | +32.66% | 99.0% |
| Since inception (from 2024-06-25) | +40.24% | +45.15% | 89.1% |
Notice the 1-year line: IWMI actually beat its index. Now notice that the answer changes with the window. A reader who checks the 1-year sees a fund outrunning the Russell 2000. A reader who checks the 6-month sees 89%. And a reader who measured only the second half of 2024 (2024-07-01 to 2024-12-31) saw capture of just 57%.
