Zacks Bull and Bear of the Day Highlights: Acusphere, ProQuest Company, Kongzhong and U.S. Steel.

CHICAGO -- Zacks Equity Research highlights Acusphere, Inc. (Nasdaq:ACUS) as the Bull of the Day and ProQuest Company (NYSE:PQE) as the Bear of the Day. In addition, Zacks Equity Research provides analysis on Kongzhong (Nasdaq:KONG) and U.S. Steel (NYSE:X). Full analysis of all four stocks is available at http://at.zacks.com/?id=2676.

Here is a synopsis of all four stocks:

Bull of the Day:

Our Bull of the Day recommendation is for Acusphere, Inc. (Nasdaq:ACUS), a specialty pharmaceutical/drug delivery company. It develops new drugs and improves formulations of existing drugs using its proprietary microparticle technology. We are impressed with the science and technology platform at Acusphere. The lead clinical candidate, AI-700 for myocardial perfusion imaging, is in phase III trials. Although this technology is new and unproven, we believe that Acusphere stock is attractive at the current level given the very cheap valuation. We continue to rate the shares a BUY with a $9 target.

Bear of the Day:

Our Bear of the Day recommendation is for ProQuest Company (NYSE:PQE). ProQuest expects its accounting review will result in the restatement of earnings reported for fiscal years 2000 to 2004 and for the first three quarters of 2005. The company also provided 2006 revenue and EBIT guidance. Consequently, we have downgraded the stock from a Hold to a Sell, and the target price has been set to $10.

Analyst Blog:

Kongzhong (Nasdaq:KONG) recently reported its excellent financial results of the first quarter. Although the Chinese wireless value-added services market has seen increasingly intense competition, and its relationship with Chinese telecom operators has had a great effect on Kongzhong's business, Kongzhong's leading position on 2.5G platform in China will help the company make full use of the wireless value-added service opportunity in the future.

U.S. Steel (NYSE:X) is the seventh-largest steel producer in the world, the second largest integrated steel producer in North America and one of the largest integrated flat-rolled producers in Central Europe. The company's near-term profitability is expected to witness a positive trend owing to higher flat-rolled contract prices. Further, volume growth will be buoyed by capacity expansion in Europe, which is showing favorable demand trends. United Steel also has strong cash flow position. All these lead us to raise our outlook on the stock to a Buy with a six-month target price of $72.00.
