MacroShares Housing IPO Size Doubled and Auction Dates Set

MADISON, N.J., April 20, 2009 (GLOBE NEWSWIRE) -- The highly anticipated Initial
Public Offering of MacroShares Major Metro Housing Up and MacroShares Major
Metro Housing Down is scheduled to run from 1 pm April 28th through 1 pm May 5th
(Eastern Daylight Time). The initial offerings of both UMM and DMM will occur
simultaneously via an electronic auction process managed by WR Hambrecht + Co.

MacroMarkets' subsidiary, Macro Housing Depositor, doubled the number of shares
being offered during the IPO to 20 million shares of UMM and 20 Million shares
of DMM for a total offering size of $1 Billion. The increased offering amount is
a result of the high level of interest voiced by the investor community.

On May 11th, the securities will be listed for trading on NYSE Arca once the IPO
is completed.

Sam Masucci, President and CEO of MacroMarkets, commented, "U.S. residential
real estate is the largest unsecuritized asset class in the world. MacroShares
Major Metro Housing will open up this large and important asset class to the
global investor community."

"Our current financial crisis is due to a failure to manage housing risk," cites
renowned economist and MacroMarkets' co-founder, Robert Shiller. "MacroShare
Housing products will begin to fill this massive void. MacroShares Major Metro
Housing Up and Down are market-based solutions to this unprecedented financial
crisis."

MacroShares Major Metro Housing will provide investors with much needed access
to the housing asset class, allowing for investment in either the upward or
downward movement of home prices. The securities are designed to track the
change in U.S. Home Prices as measured by the closely-followed S&P/Case-Shiller
Composite-10 Home Price Index. The paired securities will have a five and a half
year term and will feature a 3x (300%) leverage factor.

The Major Metro Housing trusts will be fully-collateralized by short-term United
States Treasury Bills, overnight repurchase agreements secured by Treasury
securities, and cash. UMM and DMM were designed to offer U.S. housing exposure
with exchange traded liquidity but without issuer and counterparty credit risk.
The trusts generate quarterly distributions for MacroShares' investors when
interest income exceeds trust expenses.
