U.S. HOT STOCK FUTURES: HOT STOCKS TO WATCH

Among the companies with shares expected to actively trade in Monday's session are Allscripts Healthcare Solution Inc. (MDRX), TPC Group Inc. (TPCG) and Green Dot Corp. (GDOT).

Electronic health-records company Allscripts, which is looking to be taken private after an earlier board shakeup and legal squabbles, received first-round bids from Blackstone Group LP (BX), Carlyle Group LP (CG) and Silver Lake Management LLC, Bloomberg reported Monday, citing people familiar with the talks. Allscripts is using Citigroup Inc. (C) to run its sale and is seeking second-round offers in three to four weeks. Shares rose 7.1% to $14.27 premarket.

Petrochemical-product producer TPC Group's shares rose 11% to $45.01 premarket amid a more than $700 million takeover offer from specialty-chemicals maker Innospec Inc. (IOSP). As part of the proposal, Innospec would pursue an acquisition of all of TPC Group's common shares for an all-cash purchase in the range of $44 to $46 a share. The offer comes as investors led by Sandell Asset Management have been fighting against a $627 million bid from a pair of private-equity firms.

Green Dot shares slump as American Express Co. (AXP) decides to enter the prepaid card realm in full force, including going forward to launch Bluebird at Wal-Mart Stores Inc. (WMT) locations. American Express has been testing it for nearly a year, and March's disclosure of that caused shares of prepaid-card purveyor Green Dot--which has relied heavily on Wal-Mart customers for its own business--to slide. Green Dot shares were off 21% to $10.13 premarket.

Affymetrix Inc. (AFFX), a provider of genetic analysis technologies to pharmaceutical, diagnostic and biotechnology companies, expects third-quarter revenue to fall short of consensus estimates as a tightening academic funding environment worldwide has hurt its gene expression and eBioscience business units. Shares fell 9.7% to $3.89 premarket.

EXACT Sciences Corp.'s (EXAS) shares rise 9.2% to $12.70 premarket amid a story in Barron's saying that while the stock is risky, there could be more appreciation potential into the high teens or $20s, if the company's colon-cancer test clears key hurdles. Some investors, says Barron's, are betting that the U.S. Food and Drug Administration approval could prompt a takeover of Exact Sciences at a nice premium to the current share price by a larger health-care outfit.

 
   Watchlist: 
 

Celadon Group Inc. (CGI) projected first-quarter earnings above analyst expectations, as acquisitions have boosted the trucking company's revenue and a newer fleet of vehicles helped it cut maintenance costs.

Oclaro Inc. (OCLR) reported preliminary fiscal first-quarter revenue below its own estimates, as the optical components company pointed to slower-than-expected recovery from last year's floods in Thailand and slower-than-expected ramp of new products.

Wet Seal Inc. (WTSLA) said late Friday the head of its merchandising division, Harriet Sustarsic, has resigned and will be joining True Religion Apparel Inc. (TRLG).
