Analyst Patrick Walravens says the macro environment for B2B stocks has deteriorated, and that i2 Technologies' (ITWO
) acquisition of RightWorks will increase pricing pressures for procurement software. He downgraded all the stocks in his B2B universe by one notch: Ariba (ARBA
), Commerce One (CMRC
), VericalNet (VERT
) to market perform from buy; and PurchasePro.com (PPRO
) to buy from strong buy. He notes that his talks with Global 1000 companies confirm their reluctance to approve big-ticket software deals, and their tendency to implement tougher criteria for return on investment (ROI) analysis.
