WisdomTree Announces Annual Reconstitution of Domestic Index Families

Re-balancing Mechanism Has Historically Raised Dividend Yields and Lowered P/E Ratios of WisdomTree Indexes, distinguishing WisdomTree Indexes from Conventional Cap-Weighted Indexes

NEW YORK--(BUSINESS WIRE)--

WisdomTree Investments, Inc. (Pink Sheets: WSDT) today announced the annual reconstitution of its domestic stock indexes. The reconstitution, which went into effect December 24, 2007, reflects a rules-based investment methodology that results in the WisdomTree Indexes increasing weights in stocks and sectors that have fallen in market value relative to their fundamentals and decreasing index weights in stocks and sectors that have risen in market value relative to their fundamentals.

"Our fundamentally weighted rebalancing process is what sets us apart from the market cap-weighted indexes upon which most of today's ETFs are based," said Luciano Siracusano, WisdomTree Director of Research. "Because cap-weighted indexes have no such rebalancing mechanism, when stocks rise too much relative to their fundamentals, as technology did in 1999, those stocks command ever greater weights in a cap-weighted index. WisdomTree's fundamentally weighted methodology seeks to take some of the emotion and momentum out of index investing by weighting companies based on their contributions to observable income streams."

The WisdomTree Dividend Indexes typically weight each stock eligible for inclusion by its share of the Dividend Stream, defined as the sum of regular cash dividends being paid by all the companies in that index, based on each company's most recently declared dividend per share. The WisdomTree Earnings Indexes typically weight components by their share of the Earnings Stream, defined as the sum of the aggregate earnings generated by all the companies in that index. Thus, component weights in a WisdomTree index typically equals its contribution to the total Dividend Stream or Earnings Stream for that index as of the annual screening date.

Growth in the Dividend and Earnings Streams

The total U.S. Dividend Stream, as measured by the WisdomTree Dividend Index, grew 8.4% from the prior year to $288.5 billion, as of November 30, 2007. The Earnings Stream, as measured by the WisdomTree Earnings Index, grew 2.9% from the prior year to $919.6 billion, as of November 30, 2007, the annual screening date.

"Investors are used to rebalancing their portfolios among asset classes based on relative value - WisdomTree applies this concept within broad-based stock indexes," added Mr. Siracusano. "Re-setting component weights, once a year, to a measure of fundamental value, such as dividends or earnings, has helped to lower the volatility and increase historical long-term returns of the WisdomTree Indexes relative to comparable cap-weighted indexes."

Valuation ratios for the WisdomTree Indexes tend to be lower than cap-weighted indexes, and the gap between the two widened on the most recent re-balance date. The chart below shows dividend yields and the P/E ratios for the WisdomTree indexes before and after the 2007 reconstitution.

Some performance data for the Wisdom Tree Indexes is based on a back test, i.e., calculations of how an index might have performed in the past had it existed. Hypothetical back tested performance has inherent limitations and is not indicative of future results. Index performance data assumes reinvestment of dividends and does not reflect management fees, transactions costs or other expenses. You cannot invest directly in an index.

All information is provided strictly for educational and illustrative purposes only. No representation is being made that any investment will achieve performance similar to those shown. The information provided is not intended for trading purposes, and should not be considered investment advice.

Index performance does not represent actual fund or portfolio performance. A fund or portfolio may differ significantly from the securities included in the Index. Index performance assumes reinvestment of dividends, but does not reflect any management fees, transaction costs or other expenses that would be incurred by a portfolio or fund, or brokerage commissions on transactions in Fund shares. Such fees, expenses and commissions could reduce returns. Additional index information is available at www.wisdomtree.com.

1964 was selected as the starting point of the back test of the domestic WisdomTree Dividend Indexes because WisdomTree Investments believes this is the earliest date for which reliable historic stock price data is available for the securities included in the domestic dividend Indexes covered by the back test.

March 1, 2002 was selected as the starting point of the back test for the WisdomTree Earnings Indexes because this is the earliest date for which four prior quarters of core earnings data was available for the securities included in the Earnings Indexes covered by the back test. The WisdomTree Earnings Indexes utilize Standard & Poor's "core earnings" data in connection with the selection and weighting of index constituents.

The WisdomTree Earnings Indexes are the exclusive property of WisdomTree Investments, Inc., which has contracted with Standard & Poor's ("S&P") to maintain and calculate the Indexes. S&P shall have no liability for any errors or omissions in calculating the Indexes.
