As the leveraged buyout market (LBO) tightens amid the backdrop of more expensive debt, deal makers are looking to ride new investment vehicles to make their minions money.

We've seen a surge in popularity in what's called a "Special Purpose Acquisition Company," or SPAC. Bloomberg had a good article this morning on advent of the SPAC and what's happening in the industry as a whole. These companies, also called blank-check companies, are IPO'd after raising their funds. Once public, the founding management team needs to make an acquisition in a given time-frame. Shareholders decide on an individual basis whether they like the deal or not. If they like it, great. If not, they tender their shares and receive their money back.

Essentially, it's a hedged bet on management that their industry expertise will lead to a smart acquisition.

Bloomberg says that since the start of 2003, 144 blank-check companies have sold shares, raising $18.1 billion, with 13 of the deals coming before 2005, according to SPAC Analytics.

Jamba Juice (NASDAQ: JMBA) has been an extremely disappointing performer since it went public through its acquisition by a special purpose acquisition vehicle.

Shares closed at $3.39 on Monday, down from a 52-week high of $11.25 on this day of last year -- A spread of 365 days between the current price and the 52-week high is usually a sign of a difficult stretch.

Perhaps things are getting better: Jamba Juice has reached a deal with Nestle to sell its products at groceries stores in eight states in the western United States. The plan is to eventually expand the program nationally, perhaps internationally, and also target convenience stores and other possible outlets. Nestle (OTC: NSRGY) will manufacture and distribute the beverages.

With its stock in the toilet in light of operational underperformance, this may be just what Jamba needs. But as anyone who witnessed the Krispy Kreme (NASDAQ: KKD) saga can attest, rapid expansion by a premium stand-alone specialty food retailer into mass market distribution can lead to bad results: big losses and irreparable damage to the brand.

Savvy marketing and responsible stewardship of the Jamba franchise on the part of management could make this a big success. But if the company's performance as a public company is any indication, that's not something investors should bet on.

MAJOR PAPERS:

• Next year Nestle USA will sell Jamba Inc's (NASDAQ: JMBA) Jamba Juice at stores in eight states in the western U.S., according to the Wall Street Journal.
• Last May Canadian information provider The Thomson Corporation (NYSE: TOC) bought Reuters Group Plc (NASDAQ: RTRSY) for GBP8.7B. While the deal was beneficial to Reuters, the credit crunch could have a severe impact on its bottom line over the next few years, the Wall Street Journal's "Heard on the Street" said.

OTHER PAPERS:

• The Detroit News reported that the United Auto Workers signed a new contract with Ford Motor Company (NYSE: F).

WEB SITES:

• Jeffrey Zucker, General Electric Company's (NYSE: GE) NBC Universal media unit would be interested in DreamWorks SKG if it were to become available, Bloomberg reported.
• According to 21st Century Business Herald's website, Baosteel Group's Chairman, Xu Lejiang, said the company is considering making a bid for Rio Tinto Plc (NYSE: RTP).

Ready to make some serious money? Wall Street Warrior Timothy Sykes isn't playing around -- he wants to make you rich. In this edition of StockWatch: Between the Bells, the MSN Money host and author of An American Hedge Fund: How I Made $2 Million as a Stock Operator & Created a Hedge Fund riffs -- and dances -- on a fistful of market strategies.

Tim has three daring tips for you. Digital content storage provider Isilon Systems (NASDAQ: ISLN) is sitting at an all-time low, more than 70% off its high at the start of the year, and looks priced to buy. Genetics biotech Illumina Inc. (NASDAQ: ILMN) is currently trading around $52; Tim sees ILMN climbing to $60. Sound a little too risky? Tim suggests checking out The Bruce Fund (BRUFX), a mutual fund focusing on domestic common stock, convertible bonds and zero-coupon government bonds.

Considering a short-selling strategy? Tim calls out China Precision Steel (NASDAQ: CPSL), which has jumped more than three-fold in little more than a week and looks set to slide.

Jamba Juice (NASDAQ: JMBA), meanwhile, is giving Tim fits -- revenues are up while same-store sales are slipping. He advises to stay away from JMBA.

Enjoy the clip, and let us know which of your favorite stock gurus you'd like to hear from in the next StockWatch: Between the Bells!
