UDOW targets three times the Dow Jones Industrial Average’s daily return before fees and expenses—not three times the Dow’s return over October. Because it resets exposure daily, results over multiple days depend on the path the index takes as well as its overall direction. The October watchlist framing is not a forecast or a recommendation to trade.
What is UDOW?
ProShares UltraPro Dow30 (NYSE Arca ticker: UDOW) is a leveraged exchange-traded fund that seeks daily investment results, before fees and expenses, corresponding to three times the daily performance of the Dow Jones Industrial Average (DJIA). ProShares defines the objective over one day, from one net asset value (NAV) calculation to the next. ProShares’ UDOW fund page states the daily target.
UDOW is not simply a basket of Dow stocks whose returns are multiplied by three. It uses financial instruments, including derivatives such as swaps and futures, and rebalances daily toward its target. The index itself comprises 30 large U.S. companies, excluding companies in transportation and utilities; its provider selects constituents using factors that include reputation, sustained growth, and investor interest, then weights them by share price. Constituents can change. These details are described in the UDOW summary prospectus.

If the DJIA rises 1% from one NAV calculation to the next, the fund’s stated objective is a 3% gain for that same interval, before fees and expenses. If the index falls 1%, the target corresponds to a 3% loss. That is a one-day objective, not a standing promise for longer periods.
#1 Best Overall
The prospectus is explicit: “The Fund does not seek to achieve three times (3x) the daily performance of the Index (the ‘Daily Target’) for any period other than a day.” Daily returns compound, so UDOW’s result over a week, month, or October can differ substantially from three times the index’s cumulative return. The relationship can be affected by the sequence and size of daily moves, volatility, fees, and financing and transaction costs.
Why the daily reset matters
To maintain a daily leverage target, exposure is adjusted as the fund’s net assets change. A hypothetical example from Direxion’s explanation of daily targets illustrates the mechanics for a generic 3× bull fund, not UDOW’s actual positions: starting with $100 million in net assets and $300 million of exposure, a 1% index gain raises net assets to $103 million and exposure to $303 million. Restoring exposure to 300% of assets requires adding $6 million. After a 1% index decline, net assets would be $97 million and exposure $297 million; restoring the target requires removing $6 million.
Those adjustments mean that the route to an index’s ending value matters. Repeated ups and downs can erode a leveraged fund’s multi-day result even if the index ends near where it started. Conversely, sustained moves with lower volatility can produce a different outcome. There is no fixed conversion from the Dow’s monthly return to UDOW’s monthly return.
Can UDOW lose money when the Dow rises?
Yes. The prospectus warns that an investor can lose money over a holding period even if the index rises, because volatility and daily compounding can work against the fund’s objective. A flat index return does not ensure a flat UDOW return either. For scale, the prospectus includes a hypothetical one-year illustration in which a 0% index return and 50% annualized volatility produce an estimated fund return of -52.8%. That illustration assumes no dividends, expenses, or borrowing costs; it is neither actual performance nor a forecast.
ProShares reports that, for the five years ended May 31, 2026, the DJIA’s annualized historical volatility was 14.79%, with a highest May-to-May volatility rate of 17.52% in the period ending May 31, 2023. The index’s annualized total return over that same five-year period was 10.18%. These are historical figures cited in the prospectus, not predictions; the filing warns that historical volatility and performance do not predict future results.
Risks to understand before putting UDOW on a watchlist
- Leverage and loss: Leverage magnifies losses as well as gains. The prospectus warns that if the index approaches a 33% loss at any point during a day, an investor could lose the entire investment.
- Holding period and volatility: Multi-day results can depart sharply from three times the index’s cumulative return. The prospectus says losses are possible even when the index rises.
- Derivatives and counterparties: Swaps and futures introduce costs and risks, including counterparty and correlation risks. Derivative costs reduce returns.
- Market price versus NAV: UDOW shares trade on an exchange and can trade above or below NAV. Intraday share-price performance may differ from the fund’s NAV-to-NAV daily objective.
- Not a complete investment program: The prospectus says UDOW may not be suitable for all investors and is not a complete investment program.
What UDOW costs—and what the stated expense ratio excludes
The summary prospectus lists a 0.75% management fee, 0.19% in other expenses, and 0.94% in total annual operating expenses. It also describes an agreement to waive fees or reimburse expenses so specified expenses remain at or below 0.95% through September 30, 2027, subject to the agreement’s terms. The expense table does not include transaction and financing costs associated with securities and derivatives. Check the latest filing for current terms before comparing costs.

A watchlist can help you monitor a security without implying that it is a buy or that the market has a particular near-term direction. No October 2026 market outlook or trade recommendation follows from UDOW’s stated objective. For a useful watchlist, distinguish the fund’s design from observed market data and consider:
- UDOW’s market price and NAV, including any premium or discount;
- daily trading volume and bid-ask spread, which affect the practical cost of trading;
- the Dow’s daily moves and volatility, rather than assuming the monthly index return maps directly to UDOW;
- the fund’s latest prospectus, costs, and disclosures; and
- whether the daily-reset structure and need to monitor exposure fit the intended holding period and risk tolerance.
For comparisons with other leveraged funds, use consistent criteria: daily leverage multiple and benchmark, operating expenses plus financing and trading costs, index construction and concentration, liquidity, volatility-related compounding, and intended holding period. A larger leverage multiple or recent return alone does not establish that one fund is a better fit.
