2x Gold ETF: UGL vs UGLD, Futures or Spot, and Sizing

Between the sixth and tenth business days of certain months, the index behind ProShares Ultra Gold sells its expiring COMEX gold futures and buys the next contract, roughly a fifth of the position each day. GLD never does that. It holds bars. So a fund that doubles the futures index and a fund that doubles GLD will move almost in step on most afternoons, and they can still end a three-month hold in different places, for reasons that show up in the holdings file.

Every fund detail that follows was checked in October 2026 against the sponsor’s fund page, daily holdings file or prospectus. Prices, fees and returns move daily. Read them on those pages.

Where does each 2x gold fund get its gold?

None of them own metal.

UGL. ProShares sets UGL’s objective at twice the daily performance of the Bloomberg Gold Subindex, before fees and expenses, which ProShares describes as gold measured through the price of COMEX gold futures. The fund started on December 1, 2008. Its holdings on October 23, 2026 were gold index swaps with Citibank, UBS and Goldman Sachs, a position in the December 2026 COMEX gold contract, and cash, part of it in a ProShares money market ETF. The sponsor places UGL inside ProShares Trust II, which the Commodity Exchange Act classes as a commodity pool, and says the fund has none of the protections of the Investment Company Act of 1940.

UGLD. Direxion’s stated goal is 200% of gold’s daily price performance. The SPDR Gold Trust is named as the initial reference ETP, and Direxion keeps the right to use others. Launch date: May 27, 2026. Direxion calls it an industry first, a 2X daily target on spot gold. The holdings file for October 26, 2026 showed swap agreements on GLD with several banks and the remainder in government money market funds, with no GLD shares and no futures. Rafferty Asset Management, the adviser, rebalances at each close.

GLL. ProShares UltraShort Gold seeks two times the inverse of that same Bloomberg index each day, opened on the same date as UGL, and holds the mirror image of the UGL book: short the December 2026 gold contract and short the index swaps.

Futures index or GLD: does the route matter?

Over one session, barely.

Over a quarter, it can. Gold futures usually trade above spot by roughly what it costs to finance and store metal until the delivery date, and as a contract nears expiry that premium shrinks toward nothing, after which the index rolls into a new contract carrying a fresh premium, so a futures index tends to trail spot gold by about that carrying cost over time. ProShares notes that its index counts no income on cash. The fund’s own cash does earn interest. That offsets part of the carry, by an amount that depends on short-term rates.

UGLD pays its toll elsewhere. A swap on GLD hands over GLD’s return, which is gold less the trust’s own fee, and the bank on the other side charges for financing the exposure. Direxion lists swap financing among the costs left outside its expense cap.

The working rule: for a trade lasting hours or a session or two, choose on spread and volume, which the quote shows, and for a hold of several weeks judge UGL against twice the futures index and UGLD against twice GLD, each measured from your entry date.

How does the daily reset compound on gold?

At each close the fund resizes so the next session starts at exactly 2x, or -2x for GLL. Gains are levered up. Losses shrink the base. The result over any stretch longer than a day depends on the path.

A trending month reverses the sign. Ten straight up days help the 2x fund beyond twice gold’s gain.

For a longer horizon there is a compact approximation. A 2x daily fund on a reference that ends a year flat finishes about 1 - e^(-σ²) lower, where σ is the reference’s annualized volatility. Direxion’s summary prospectus for UGLD prints a table with the same shape: a flat reference year at 25% annualized volatility leaves the fund an expected 6.1% lower, and at 10% volatility, 1.0% lower. Gold usually swings less than a single stock, so the drag builds slowly, though it builds on every day the position stays open. The leveraged ETF decay calculator runs any path you type in.

How big should a 2x gold position be?

Size it from the fund’s own average true range. The leverage then takes care of itself.

The leverage freed $8,280 of cash and left the size of the gold bet where it was. Putting the usual GLD dollar amount into the 2x fund doubles the risk of the trade. Take the ATR from the fund’s chart. Resets and trading costs keep it off exactly twice the reference’s.

How long can you hold UGL or UGLD?

ProShares’ fund description allows a hold longer than a day and warns that for any period other than one day the return can come out higher or lower than the daily target, sometimes by a wide margin; small gold moves and high volatility push it below, large moves and calm push it above.

Treat the holding period as a rule you set at entry. Write down the reference price and the fund price. Each evening, compare the fund’s change since entry with twice the reference’s. If the gap passes a limit you chose in advance, close or cut the position, because the trend you wanted has turned into chop.

In practice that keeps most holds to days or a few weeks.

How are UGL, UGLD and GLL taxed?

• UGL and GLL. ProShares states that each generates a K-1, the partnership form that reports your share of the pool’s income and gains for the year. It often arrives after the 1099s.
• UGLD. Direxion’s fund page says UGLD avoids a K-1. Its prospectus says distributions may be taxed as ordinary income or as long-term capital gains.
• Your own sale. Sell within a year of buying and any gain is short-term, so it meets your ordinary income tax rate, which is where most leveraged gold trades land.

Bullion trusts carry their own collectibles treatment, which the gold ETF list covers. Situations differ. A tax professional can say how the forms land on your return.

What else gives leveraged gold exposure?

• Calls on GLD. Your loss stops at the premium paid. Time decay works against you each day, and the strike and expiry are fixed when you buy.
• Margin on a bullion trust. Borrowing to buy more GLD, IAU or another trust leaves no daily reset to compound against you. The loan stays fixed while gold moves, so a falling price raises your leverage until a margin call arrives, and you pay interest the whole time. The Federal Reserve’s Regulation T caps what you can borrow at the start; your broker’s agreement sets the maintenance level.
• GLL for the other side. A short view on gold for a few days fits the -2x fund, with every reset rule above applied in reverse. The inverse ETF list sets out the stock-index funds that run on the same daily reset at -1x, -2x and -3x.

Whichever route you take, size it from the risk to the stop. Decide the exit before the order goes in.
