What Is MVLL and Why 60 of Its 84 Sessions Breached a 10x Stop

MVLL is the GraniteShares 2x Long MRVL Daily ETF, and 60 of the 84 daily bars Phemex holds for it breached a 10x liquidation stop. The fund's own page targets 2x the daily percentage change in Marvell Technology stock, and daily is the word that bites.

Stack the 10x Phemex allows on MVLLUSDT onto a fund that already doubles Marvell's daily move and you're carrying about 20x the stock for one session. Tier 1 of the contract's margin table sets maintenance at 5 percent, so a 10x isolated position dies on a 5.00 percent adverse move. The median daily move across those 84 sessions was 5.53 percent.

What Is MVLL and What Sits Inside the Fund

MVLL is a 2x leveraged ETF of the single-stock kind, and GraniteShares Advisors runs it on NASDAQ. The objective it files with the SEC reads the same way in every document. The fund seeks daily investment results, before fees and expenses, of 2 times the daily percentage change of Marvell Technology common stock. Marvell designs custom silicon for hyperscalers, and our 2026 outlook on Marvell stock covers the demand cycle the share price trades on.

The two primaries disagree about the launch. The fund page dates inception to 7 March 2025 and the audited annual report's fund statistics line gives 6 March 2025.

They disagree about the holdings too. The fund page says MVLL gets its exposure through total-return swaps collateralised by cash and short-term Treasuries. The summary prospectus filed on 24 October 2025 describes something wider. Its Principal Investment Strategies paragraph has the fund replicating the move "by entering into financial instruments such as swaps and options Underlying Stock as well as directly purchasing the Underlying Stock." We report both and settle neither, because a schedule of investments is the only place a holding gets proved.

What the audited schedule proves for 30 June 2026 is seven holdings. Treasury bills are 38.91 percent of total investments and five Marvell total-return swap lines add up to 50.86 percent. Broker cash carries the remaining 10.22 percent, and portfolio turnover for that fiscal year was zero.

The Daily Reset Inside a 2x Leveraged ETF

GraniteShares prints the warning itself. "The fund should not be expected to provide 2 times the cumulative return of MRVL for periods greater than a day," says the annual shareholder report for the year to 30 June 2026.

A daily leveraged ETF resets its notional exposure to 200 percent of net asset value at the end of every trading day. In a trend that compounding pays you far more than double. In a chop it grinds your position down while the stock goes nowhere. For the twelve months to 30 June 2026 the fund returned 651.05 percent at NAV. From its first Phemex close of $57.27 on 30 June to the $34.87 close on 21 September it gave back 39.11 percent. Same fund and same mandate, with the direction of the tape as the only thing that changed.

We measured the same daily-reset arithmetic on the 2x SanDisk fund and it cut the other way, which most explainers on compounding skip entirely.

Why 60 of 84 MVLL Sessions Breached a 10x Stop

Method: tier 1 of leverage-margin set 1040 in the Phemex product file caps MVLLUSDT at 10x and sets maintenance margin at 5 percent. That leaves a 10x isolated entry 5.00 percent of room. We then counted every daily bar from 30 June to 21 September 2026 where the high or the low travelled 5.00 percent from that session's own open.

Sixty of the 84 did, or 71.4 percent. Thirty-five sessions killed a long, 41 killed a short, and 16 killed both from the same open. The longest stretch that left both sides alive ran three sessions.

Take 31 July 2026. The contract opened at 21.50, ran to 23.35 and dropped to 19.95. That is 8.60 percent up and 7.21 percent down from one open, so a 10x long and a 10x short entered there were both gone by the close. On the 21 September anchor session the open was 30.99 and the high was 35.23. The short liquidated at plus 13.68 percent while the long survived on a low of 30.97. The MVLL liquidation distance never moved, and the contract walked through it twice on 31 July and once more on 21 September. How a liquidation engine actually closes you out is a separate mechanism from the distance, and the two get confused constantly.

What Happens When You Stack 10x on the MVLLUSDT Perpetual

Two layers of leverage multiply, they don't add. The fund doubles Marvell's daily move, the MVLLUSDT perpetual multiplies the fund by up to ten, and for a single session your stacked position tracks about 20x the stock. Hold it longer and that clean multiple breaks, because the swap book resets daily and your perpetual position does not.

The fee layers stack the same way. GraniteShares caps total annual fund operating expenses at 1.50 percent to 31 December 2026, and the cap text explicitly carves out swap fees and expenses. The same filing then estimates the indirect cost of investing in swaps at 1.50 percent for the fiscal year ending 30 June 2026. MVLLUSDT settles funding every 28,800 seconds on top of that. You pay three times a day at 00:00, 08:00 and 16:00 UTC.

One route out of the stack is closed on our own board. The 22 September product file carries 891 perpetual rows and 1,177 spot rows, and exactly one of them mentions Marvell. That row is MRVLUSDT, which listed on 15 May 2026, and its perpetual is delisted. What is live is the fund, and TradFi perps that move when Wall Street is shut price MVLL through weekends the ETF itself never sees.

What the 3-for-1 Split Did to the MVLL ETF Chart

GraniteShares announced forward splits on 12 June 2026 and MVLL went 3 for 1. The record date was 24 June and payment followed after the close on 25 June. Post-split trading began before the open on 26 June, and Phemex listed the contract four days later at 10:00 UTC on 30 June 2026.

That sequence is why the series is usable. A kline series that straddles a forward split carries the redenomination inside a single bar, which prints an intraday collapse that never happened and poisons every average computed over it. All 84 MVLL bars sit on one basis.

The listing mark checks out against the audited book. Net asset value per share was $57.43 at 30 June 2026 and the first Phemex close that day was $57.27. The gap is 0.27 percent. GraniteShares serves a dash for live assets under management on its own fund page, so the audited 30 June figure is the only one we'll quote.

One denominator note on the anchor. The Monday 21 September close of $34.87 is 12.41 percent above the Sunday 20 September close of $31.02. Sunday turnover was $240,778 against Monday's $1,076,770. Measured from the Friday 18 September close of $30.72, the last session the US cash market actually traded, the move is 13.51 percent. What TradFi futures are explains why a stock perp carries weekend bars at all.

Frequently Asked Questions

What does MVLL cost to hold?

The prospectus fee table shows 2.52 percent gross and 1.50 percent net. The annual shareholder report gives an actual expense ratio of 1.37 percent for the twelve months to 30 June 2026. It puts the cost of a hypothetical $10,000 holding at $598.42 over that period.

Who are the swap counterparties?

The 30 June 2026 top-holdings table names five of them. Cantor carries 21.88 percent of total investments and Marex 18.35 percent. HSBC holds 6.26 percent, Clear Street 3.79 percent and National Bank of Canada 0.58 percent.

What has MVLL returned since inception?

The annual report gives an average annual total return of 332.66 percent since inception, measured at 30 June 2026. The S&P 500 Total Return Index, which the report uses as the comparison, returned 24.06 percent a year over the same span.

How low has MVLLUSDT traded on Phemex?

Its lowest daily close in the 84-bar series is $15.71 on 29 July 2026. The next session closed at $22.01 on 30 July for a 40.10 percent gain. No other bar in the series has printed a bigger one-day move.

The Bottom Line

MVLL hits its target almost every single day, and the target is the hazard. Doubling a volatile chip stock's daily move produces a median session of 5.53 percent, and a 10x isolated entry has 5.00 percent of room before the engine takes you out. Those two numbers were always going to collide. Across 84 sessions they collided 60 times.

Size your position off the median daily move, not off the leverage cap the venue hands you. The stack is the risk, and the stack is optional.
