The short version
T-REX 2X Long RBLX Daily Target ETF (RBLU), from Tuttle Capital Management, is a leveraged fund that seeks twice the daily return of one stock, Roblox Corp. (RBLX). It does this mainly through swaps, which are contracts with financial institutions. Because its 2x exposure resets daily and depends on a single company, losses can build quickly: shares fell 68.8% between July 1 and August 12, 2026. It charges 1.05% a year and is built for short-term trading.

What changed recently
- Over the three months to Jun 30, 2026, investors added a net $6.5M (creations minus redemptions, per the N-PORT report).
- Monthly total returns reported for that quarter: -7.74%, -34.69%, +24.79%.
How it works
RBLU does not follow an index. Its manager aims for 200% of Roblox's daily price change, before fees and expenses, measured from one market close to the next. The main tool is swaps: contracts in which financial institutions agree to pay the fund twice Roblox's daily return on its net assets. The fund may also hold exchange-listed call options, which are rights to purchase shares at a set price. It can also hold Roblox stock itself, though stock alone adds no leverage. As of June 30, 2026, it reported two Roblox swaps, one with Cantor, plus cash.
At each market close, the manager resets exposure to 2x. After Roblox rises, the fund adds exposure. After it falls, the fund trims it. Because returns compound daily, results over weeks or months can differ sharply from twice Roblox's return, especially when the stock swings up and down. If Roblox drops more than 50% in a single trading day, investors would lose all their money.
Alongside the swaps, the fund keeps cash-like holdings such as money market funds, bank deposits and short-term U.S. government securities. It may also use The Laddered T-Bill ETF, a fund in the same family. If a swap counterparty fails to pay, the fund could lose money. It is non-diversified and concentrated in the entertainment industry.
What it really costs
- RBLU charges 1.05% a year.
- Using the prospectus's standard example, $10,000 invested would cost about $107 in the first year and $1,281 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| RBLU | $107 | $334 | $579 | $1,281 |
In a retirement portfolio
RBLU resets to twice Roblox's daily return each day, so its results over months can stray far from the stock's, and one very bad day for Roblox could wipe it out.
RBLU launched on March 4, 2025, so it has no record through the 2008 financial crisis, the 2020 COVID crash or the 2022 bear market. Its price history begins June 9, 2026, so there is no full calendar year to judge. In that short span, its deepest drop was 68.8%, from July 1 to August 12, 2026. Shares had not regained that peak as of October 27, 2026. Anyone forced to draw cash after a fall like that would lock in heavy losses.
It adds no income: the yield was 0% over the 12 months to October 27, 2026. It costs 1.05% a year. Under the Securities and Exchange Commission's (SEC) standard example, that comes to $107 in year one on a $10,000 investment. Past results don't predict the future, and a retirement plan needs to look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Active traders seeking twice Roblox's daily move over short periods who can check the position every trading day.
- Investors who understand daily resets and swaps and accept that a one-day Roblox drop of more than 50% would wipe out the fund.
- Those with a strong short-term view on Roblox who accept a 1.05% expense ratio and no income in exchange for amplified exposure.
Look elsewhere if
- Retirees and savers seeking steady growth or income: RBLU yielded 0% over the 12 months to October 27, 2026.
- Anyone uneasy with steep drops, like the 68.8% fall from July 1 to August 12, 2026, still unrecovered by October 27, 2026.
- Investors wanting diversification: the fund is non-diversified, tied to a single entertainment company, and exposed to the swap counterparties that deliver its leverage.

Questions investors ask
What is the RBLU ETF and how does it work?
RBLU is the T-REX 2X Long RBLX Daily Target ETF, issued by Tuttle Capital Management. It seeks 200% of the daily performance of Roblox Corp. (RBLX), before fees and expenses. Roblox runs an online entertainment platform. The fund mainly uses swap agreements with financial institutions and may also use call options or hold Roblox shares. Exposure resets to 2x at each market close. The fund launched on March 4, 2025, and had net assets of about $13 million as of June 30, 2026.
Is RBLU a good long-term investment?
It is not built for long-term holding. RBLU targets twice Roblox's return for one trading day only. Over longer periods, daily compounding can push results far from twice the stock's return, especially when Roblox swings up and down. Shares fell 68.8% from July 1 to August 12, 2026, and had not recovered as of October 27, 2026. The prospectus warns that investors could lose all of their money.
What's the difference between RBLU and Roblox stock?
The main difference is leverage. RBLU aims to double Roblox's daily move, while RBLX shares give one-for-one exposure with no expense ratio, no daily reset and no swap counterparty. RBLU charges 1.05% a year, and over periods longer than a day its return can differ widely from twice the stock's. A single-day Roblox drop of more than 50% would wipe out the fund, while stockholders would keep whatever value remained.
Does RBLU pay dividends?
It paid nothing in the 12 months to October 27, 2026, when its trailing yield was 0%. Its distribution frequency is listed as annual. The fund's return comes from leveraged exposure to Roblox's share price through swaps, not from income. That makes it a poor fit for investors who need regular cash from their holdings, such as retirees drawing on a portfolio for living expenses.
What is RBLU's expense ratio?
RBLU's expense ratio, the yearly fee taken from fund assets, is 1.05%. All of it is a management fee, according to the prospectus filed April 30, 2026. Under the SEC's standard example, a $10,000 investment earning 5% a year would cost about $107 over one year, $334 over three, $579 over five and $1,281 over ten. The fee is charged whether Roblox rises or falls.
