Investment Objective
The WisdomTree Bloomberg U.S. Dollar Bullish Fund (the “Fund”) seeks to provide total returns, before fees and expenses, that exceed the performance of the Bloomberg Dollar Total Return Index (the “Index”).
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy and hold shares of the Fund. The fees are expressed as a percentage of the Fund’s average net assets.
Shareholder Fees (fees paid directly from your investment) None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)  
Management Fees 0.50%
Distribution and/or Service (12b-1) Fees None
Other Expenses 0.00%
Total Annual Fund Operating Expenses 0.50%
Example
The following example is intended to help retail investors compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that such investors would incur over various periods if they were to invest $10,000 in the Fund for the time periods indicated and then redeem all of the shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. This example does not include the brokerage commissions that retail investors may pay to buy and sell shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, there was no portfolio turnover rate for the Fund since the Fund invested in short-term securities with maturities less than or equal to 365 days, which are excluded from portfolio turnover calculations.
Principal Investment Strategies of the Fund
The Fund is an actively managed exchange traded fund (“ETF”) that seeks to provide total returns, before fees and expenses, that exceed the performance of the Index. The Index is structured to potentially benefit as the U.S. dollar appreciates relative to a basket of global currencies. The Index tracks a long position in the U.S. dollar measured against a basket of developed and emerging market currencies which (i) have the highest liquidity in the currency markets and (ii) represent countries that make the largest contribution to trade flows with the United States. The Index also incorporates differences in money market rates between the U.S. and the countries (or regions) represented by the foreign currencies.
The Fund will seek exposure to both the U.S. dollar and global currencies held by the Index through investing, under normal circumstances, at least 80% of its assets in money market securities and other liquid securities, such as short-term investment grade government and corporate debt securities, combined with currency forward contracts in the individual component currencies of the Index (a currency forward contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract). If a sufficiently liquid futures contract on the Index or related index is later developed, the Fund may invest in such futures contract as a substitute for or in combination with forward contracts on the individual currencies. The Fund also may enter into repurchase agreements, which are transactions in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. If, subsequent to an investment, the 80% requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.
The Fund’s positioning for a stronger U.S. dollar through a mixture of securities and financial instruments is intended to provide a return reflective of the change in the value of the U.S. dollar relative to the basket of global currencies while incorporating differences in money market rates between the U.S. and the countries (or regions) represented by the foreign currencies. The Fund expects its holdings to represent approximately ten (10) currencies at any given time, with the euro expected to represent the largest exposure in the global basket of currencies, but at no time is the Fund’s exposure expected to exceed twenty (20) currencies (Index maximum). The Fund, similar to the Index, is not designed to benefit if the value of the basket of global currencies appreciates relative to the U.S. dollar.
The Fund generally will maintain a weighted average portfolio maturity with respect to short-term investment grade government and corporate debt securities of two (2) years or less and money market securities of 180 days or less on average (not to exceed 18 months) and will not purchase any money market securities with a remaining maturity of more than 397 calendar days. The “average portfolio maturity” of the Fund will be the average of all current maturities of the individual securities in the Fund’s portfolio. The Fund’s actual portfolio duration may be longer or shorter depending on market conditions.
Principal Risks of Investing in the Fund
You can lose money on your investment in the Fund. Further, although the Fund invests primarily in money market securities, the Fund is NOT a money market fund and does NOT seek to maintain a stable net asset value per share (“NAV”). The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund’s NAV, trading price, yield, total return and/or ability to meet its objective. For more information about the risks of investing in the Fund, see the sections in the Fund’s Prospectus titled “Additional Principal Risk Information About the Funds” and “Additional Non-Principal Risk Information.”
2  WisdomTree Trust Prospectus


Investment Risk. As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.
Market Risk. The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors, such as economic, financial or political events that impact the entire market, market segments, or specific issuers. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and there may be times when the market price of the shares is more than the NAV (premium) or less than the NAV (discount). This risk is heightened in times of market volatility or periods of steep market declines.
Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to own or transfer currency, securities or other assets, which may potentially include derivative instruments related thereto. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell, transfer, receive, deliver or otherwise obtain exposure to, foreign securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for shares of the Fund, and cause the Fund to decline in value.
Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments in order to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
Counterparty and Issuer Credit Risk. The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations or cause such issuer or counterparty to be perceived (whether by market participants, rating agencies, pricing services or otherwise) as being in such situations. The value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults, changes in the credit ratings of the Fund’s portfolio investments and/or perceptions related thereto.
Currency Exchange Rate Risk. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may also change quickly, unpredictably, and without warning, and you may lose money.
Cyber Security Risk. The Fund and its service providers may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.
Derivatives Risk. The Fund invests in derivatives. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as a commodity, index, interest rate or inflation rate. The return on a derivative instrument may not correlate with the return of its underlying reference asset. Derivatives are subject to a number of risks described elsewhere in the Fund’s Prospectus, such as counterparty and issuer credit risk, interest rate risk, market risk and issuer-specific risk. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. In addition to the other risks associated with the use of derivatives described
WisdomTree Trust Prospectus  3


  elsewhere in this Prospectus, there are risks associated with the Fund’s use of forward currency contracts and/or futures contracts. With respect to forward currency contracts, these risks include but are not limited to the risk that the counterparty will default on its obligations. With respect to futures contracts, these risks include but are not limited to: (1) the success of the adviser’s and sub-adviser’s ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) an imperfect or no correlation between the changes in market value of the currencies or securities and the prices of futures contracts; and (3) no guarantee that an active market will exist for the futures contracts at any particular time.
Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares and cause the Fund to decline in value.
Foreign Securities Risk. Investments in non-U.S. securities involve political, regulatory, and economic risks that may not be present in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations, political or economic instability, or geographic events that adversely impact issuers of foreign securities. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments and may be heightened in connection with investments in developing or emerging markets countries.
Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in securities exposed to the currency of a single country or region, or the debt securities of companies or agencies of a single country or region, the Fund is more likely to be impacted by events or conditions affecting that country or region. The Fund currently invests a significant portion of its assets in securities exposed to the currencies of Europe and Japan.
Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war, threats of war, aggression and/or conflict, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations (including due to events outside of such countries or regions) that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.
Interest Rate Risk. Interest rate risk is the risk that fixed income securities will decline in value because of an increase in interest rates and changes to other factors, such as perception of an issuer’s creditworthiness. Funds with higher durations generally are subject to greater interest rate risk. For example, the price of a security with a ten-year duration would be expected to drop by approximately 10% in response to a 1% increase in interest rates.
Issuer-Specific Risk. Issuer-specific events, including changes in the actual or perceived financial condition of an issuer, can have a negative impact on the value of the Fund.
Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.
Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.
Repurchase Agreement Risk. The Fund’s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.

Sovereign Debt Risk. Bonds issued by governments, sometimes referred to as “sovereign” debt, present risks not associated with investments in other types of bonds. The government or agency issuing the debt may be unable or unwilling to make interest payments and/or repay the principal owed. In such instance, the Fund may have limited recourse against the issuing government or agency. In the past, governments of emerging market countries have refused to honor their payment obligations on issued bonds.
Fund Performance
Historical Fund performance, which varies over time, can provide an indication of the risks of investing in the Fund. The bar chart that follows shows the annual total returns of the Fund for each full calendar year since the Fund commenced operations. The table that follows the bar chart shows the Fund’s average annual total returns, both before and after taxes. This table also shows how the Fund’s performance compares to the Index and that of a relevant broad-based securities index. Index returns do not reflect deductions for fees, expenses or taxes. All returns assume reinvestment of dividends and distributions. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available online on the Fund’s website at www.wisdomtree.com.
The Fund’s year-to-date total return as of September 30, 2018 was 3.55%.
Best and Worst Quarter Returns (for the periods reflected in the bar chart above)
  Return Quarter/Year
Highest Return 7.05% 4Q/2016
Lowest Return (4.24)% 1Q/2016
After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown and are not relevant if you hold your shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases, the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.
Average Annual Total Returns for the periods ending December 31, 2017

WisdomTree Trust Prospectus  5


Portfolio Managers
The Fund is managed by the Sub-Adviser's Fixed Income Portfolio Management team. The individual members of the team jointly and primarily responsible for the day-to-day management of the Fund’s portfolio are described below.
Paul Benson, CFA, CAIA, Managing Director, Head of Fixed Income Portfolio Management, has been a portfolio manager of the Fund since October 2015.
Stephanie Shu, CFA, Director, Senior Portfolio Manager, Fixed Income, has been a member of the portfolio management team for the Fund since inception and a portfolio manager of the Fund since October 2015.
Buying and Selling Fund Shares
The Fund is an ETF. This means that shares of the Fund are listed on a national securities exchange, such as NYSE Arca, and trade at market prices. Most investors will buy and sell shares of the Fund through brokers. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount).
The Fund issues and redeems shares at NAV only in large blocks of shares (“Creation Units”), which only certain institutions or large investors (typically market makers or other broker-dealers) may purchase or redeem. Currently, Creation Units generally consist of 100,000 shares, though this may change from time to time. Creation Units are not expected to consist of less than 25,000 shares. The Fund issues and redeems Creation Units in exchange for a portfolio of securities and/or U.S. cash.
Tax Information
The Fund intends to make distributions that may be taxed as ordinary income or capital gains.
Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), WisdomTree Asset Management or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
