What Is OMFL? Invesco Russell 1000 Dynamic Multifactor ETF

Last updated September 2026

Short answer

OMFL is Invesco Russell 1000 Dynamic Multifactor ETF, an ETF that tracks the Russell 1000 Dynamic Multifactor Index at a 0.29% expense ratio. OMFL does not hold a fixed set of factor tilts. Its index reads a set of macroeconomic and market indicators, classifies the current environment into a regime, and adjusts which factors it emphasises accordingly. A holdings list therefore describes the fund at one moment rather than telling you what it is. At present Apple leads at 8.0 percent, a striking weight for a rules-based fund, with Microsoft at 4.9 percent and NVIDIA at 4.8 percent behind it. Technology is 36 percent. The fee is 0.29 percent, the yield 0.81 percent and assets $4.7 billion.

Dynamic means the rules themselves change

Most factor funds pick a tilt and hold it. A value fund stays tilted to value through the periods when value is out of favour, which is precisely the discipline that makes the approach work over long horizons for those who stay invested. OMFL takes a different position: it argues that different factors work in different economic conditions, and that identifying the current condition is a tractable problem.

The index behind it therefore classifies the environment using economic and market indicators and shifts emphasis between the standard factor set, which strategies of this type typically draw from value, quality, momentum, size and low volatility. Anyone assessing the fund is assessing that regime signal, not the factors themselves. If the classification is right often enough, the rotation adds value. If it lags turning points, the fund can arrive at each tilt after the useful part has passed. The methodology document is where the actual signal is specified.

What the current portfolio happens to look like

Apple at 8.0 percent is a large weight for a rules-based fund, well ahead of Microsoft at 4.9 percent and NVIDIA at 4.8 percent. Alphabet appears in two share classes at 3.2 percent and 2.6 percent, so the company is 5.8 percent of the fund and sits second when the lines are combined. The ten largest positions total 34.2 percent, more concentrated than the parent Russell 1000 would be at these names.

There is a payments cluster underneath: Visa at 2.8 percent and Mastercard at 2.1 percent give 4.9 percent in two businesses running the same kind of network with the same regulatory exposure. Eli Lilly at 2.0 percent and Lam Research at 2.0 percent complete the top group. Technology at 36 percent leads the sector table ahead of healthcare at 13 percent and industrials at 12 percent. All of this is subject to change at the next regime shift, which is the point that separates this fund from a static factor product.

Rotation is not free

Changing factor emphasis means changing holdings, and changing holdings means trading. That produces higher turnover than a static index fund, with the associated transaction costs borne inside the fund and not visible in the 0.29 percent expense ratio. In a taxable account it can also mean more realised capital gains distributed to holders than a low-turnover index fund would generate, which is a cost that never appears in any fee table.

The 0.29 percent itself is modest for a strategy of this complexity and several times what a plain Russell 1000 tracker charges. The 0.81 percent distribution yield is the lowest kind of figure you would expect from a portfolio currently tilted toward large growth companies, and it would change if the regime signal moved the fund toward value or low volatility, both of which select higher-paying companies. Judging the fund on any single snapshot, including the yield, misses how it is meant to work.

FAQ

What does dynamic multifactor mean?

+

It describes an index that changes which investment factors it emphasises based on a reading of current economic and market conditions, rather than holding one tilt permanently. The premise is that factors such as value, quality, momentum, size and low volatility perform differently across parts of the economic cycle, and that adjusting between them can improve on holding any single one.

Which factors does it rotate between?

+

Strategies of this design typically draw from the established factor set of value, quality, momentum, size and low volatility, adjusting emphasis according to the identified regime. The precise definitions, the indicators used to classify the environment and how quickly the index responds are set out in the index methodology, which is the document that actually determines what the fund does.

Why is Apple 8.0 percent of the fund?

+

That is a large weight for a rules-based product and reflects the current factor tilt combined with Apple's size in the underlying Russell 1000 universe. It also means a single company drives a visible share of the fund's result. Because the tilt rotates, that weight is not a permanent feature, and a shift in the regime signal could reduce it considerably.

How does OMFL differ from a plain Russell 1000 fund?

+

A Russell 1000 index fund holds the thousand largest US companies weighted by market value and never deviates. OMFL starts from the same universe but reweights it according to factor signals, which produces different sector and company weights and a different pattern of returns. It charges more, trades more and can lag or lead the parent index for extended periods.

How concentrated is the portfolio?

+

The ten largest positions are 34.2 percent of assets, led by Apple at 8.0 percent. Alphabet's two share classes at 3.2 percent and 2.6 percent combine to 5.8 percent for a single company. There is also a payments cluster, with Visa at 2.8 percent and Mastercard at 2.1 percent giving 4.9 percent in two businesses with very similar economics and regulatory exposure.

Why is the yield only 0.81 percent?

+

The portfolio is currently weighted toward large growth companies that distribute little, which produces a low aggregate payout. This figure is more changeable than in a static fund: a regime shift toward value or low volatility would move the portfolio into companies that pay more. Anyone relying on the current yield as a planning figure would be misreading how the strategy operates.

Does the rotation create tax consequences?

+

It can. Shifting factor emphasis requires selling holdings and buying others, which generates higher turnover than a static index fund. The ETF structure absorbs a good deal of that through in-kind creation and redemption, but a rotating strategy still tends to distribute more realised gains than a low-turnover tracker. The effect matters in taxable accounts and not in sheltered ones.

When is OMFL the wrong tool?

+

When you want deliberate, persistent exposure to a specific factor, since the tilt here changes by design. When low turnover matters in a taxable account. And when simplicity is the priority, because assessing this fund requires forming a view on whether the regime signal works, which is a harder question than judging a static index.

What is OMFL's expense ratio?

+

OMFL has an expense ratio of 0.29% per year as of August 2026, charged by Invesco and deducted from the fund's value rather than billed to you separately. On a $10,000 position that is roughly $29 a year. Fees compound over time, so on a long-term holding the expense ratio is one of the few return drivers you control. It is worth comparing against other funds that track the Russell 1000 Dynamic Multifactor Index before you choose.

How do I compare OMFL to similar ETFs?

+

Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. OMFL's figures are above; the full method is in Walnut's guide on how to compare ETFs.
