The evolution of leveraged ETFs has taken another leap forward, with these products now seeking to compress their return target reset periods from a single trading day down to just a few hours.
According to a recent filing, Defiance ETFs submitted paperwork to the US Securities and Exchange Commission (SEC) on August 21, 2026, proposing a new lineup of leveraged funds. These vehicles would track popular tech names including Meta, Microsoft, Nvidia, Palantir Technologies, and Tesla, with the key innovation being a shift in the return calculation cycle from one trading session to a much shorter hourly window.
This structural change significantly tightens the operational timeframe of existing daily-reset leveraged ETFs, allowing for leverage to be recalibrated multiple times throughout the trading day. The application arrives at a moment when regulators are intensifying their scrutiny of leveraged ETF products. The SEC has already slowed the approval process for triple, quadruple, and even quintuple-leveraged funds, while South Korean authorities similarly tightened their own rules over the summer. Should this new product receive the green light, it would arm active traders with a more precise intraday directional betting tool, while simultaneously amplifying the risk of compounding gains and losses repeatedly within the same session.
Product Design: Hourly Resets and Six Intraday Rebalances
Based on the documentation submitted by Defiance ETFs, the proposed funds will use swap contracts or options to maintain roughly two times the exposure of the underlying securities. Unlike existing products that typically rebalance only once at the market close, these funds will execute six rebalancing events during each trading day. Each reset will rely on a time-weighted average price as its benchmark rather than a single point-in-time price.
This mechanism means that if a trader anticipates Nvidia will rally during a specific period due to a particular news event, they could buy the fund within that corresponding hourly window. The goal would be to capture approximately double the stock price movement during that particular stretch, rather than double the full-day performance. After each subsequent reset, the two-times return objective is recalculated from scratch.
Sylvia Jablonski, Chief Investment Officer at Defiance ETFs, explained that the product is designed to give investors an alternative method for expressing intraday market views. Instead of pursuing double returns from one closing price to the next, the hourly-reset offering seeks to achieve its stated multiple within a much shorter one-hour measurement period.
The Double-Edged Sword of Compounding Effects
ETF issuers have long emphasized that leveraged ETFs are closer to trading instruments than traditional buy-and-hold investments. The hourly reset structure pushes this characteristic even further. Under this new framework, each period's gains or losses become the starting point for the next period, meaning profits and losses compound repeatedly within a single trading day. If the underlying stock trends steadily upward, the mechanism can amplify returns; however, during choppy or declining markets, the same compounding effect intensifies losses and increases volatility drag.
James Seyffart, an ETF analyst with Bloomberg Intelligence, expressed a cautious view on the innovation. He noted that apart from specific hourly windows surrounding earnings reports or other announcements, he remains skeptical about whether this truly offers exposure that is fundamentally distinct from daily-reset products.
Global Regulatory Pressure Intensifies
The timing of this application reflects a broader shift in sentiment among global regulators toward leveraged ETF products. The SEC has applied the brakes to approving funds with three-times or higher leverage and is conducting a wider review of the increasingly speculative wave of new ETF offerings. In South Korea, a summer surge of retail investors pouring into leveraged funds tied to SK Hynix and Samsung Electronics ended in substantial losses and triggered significant public backlash, drawing attention even from the country's president. In response, South Korean regulators tightened their rules, requiring investors to complete a five-day simulated trading period before participating. This has led to a sharp contraction in demand for some of the country's most popular leveraged products.
Whether Defiance ETFs' application will secure SEC approval remains uncertain. Given the generally cautious regulatory stance toward leveraged products, this attempt to compress the speculative cycle down to an hourly level is likely to face even more rigorous oversight.
