MacroMarkets Lists Two MacroShares ETPs on NYSE Arca

NYSE Euronext (NYX) announced that its wholly-owned subsidiary, NYSE Arca, today began trading MacroShares Major Metro Housing Down Trust and MacroShares Major Metro Housing Up Trust, both exchange traded products (ETPs) sponsored by MacroMarkets LLC.

The MacroShares Metro Housing ETPs are based on the S&P/Case-Shiller Composite-10 Home Price Index, a closely watched indicator of U.S. home prices in the 10 largest cities.

Name and Ticker Symbol of the Two MacroShares ETPs:

• MacroShares Major Metro Housing Down Trust-Ticker Symbol “DMM”
• MacroShares Major Metro Housing Up Trust-Ticker Symbol “UMM”

MacroShares Major Metro Housing Up /MacroShares Major Metro Housing Down ETPs:

Developed by Karl Case and Robert Shiller, the Case-Shiller Composite-10 Home Price Index is a closely watched gauge of U.S. home prices. It measures single-family housing prices in the country’s 10 largest cities. MacroMarkets states that MacroShares Major Metro Housing trusts provide investors with access to the housing asset class, allowing for leveraged investment in either the upward or downward movement of home prices with no issuer or counterparty credit risk.

As described by MacroMarkets, MacroShares Major Metro Housing Up (NYSE Arca: UMM) and MacroShares Major Metro Housing Down (NYSE Arca: DMM) are paired trusts that work as follows. When MacroShares Major Metro Housing Up are created, an equal number of MacroShares Major Metro Housing Down are also created. UMM funds are invested in the “Major Metro Housing Up Trust.” DMM investor funds are invested in a separate “Major Metro Housing Down Trust.” These trusts enter into a settlement contract: a binding agreement to pledge assets to one another over time, according to a predetermined formula that is driven by changes in the Reference Index. The trusts feature a 3x leverage factor, such that the underlying value of each is intended to track three times the cumulative percentage change, upward or downward, in U.S. single family home prices, as measured by the S&P/Case-Shiller Composite-10 Home Price Index.

The above is intended only as a summary. For complete information on the effect of leverage and other risks of investment in the trusts, please refer to the trusts’ prospectuses at www.macromarkets.com.
