MOST NOTEWORTHY: Baldor Electric Co (BEZ) was today's most notable initiation:

• Shares of Baldor Electric Co (NYSE: BEZ) were initiated by Baird with an Outperform rating and $42 target. The firm believes that Baldor's already-premium market position is strengthened by their acquisition of Rockwell's Power Systems. The firm believes that as the company starts to realize integration synergies, management's initial earnings accretion forecast of $0.10 in 2007 is conservative, earnings surprises will be likely and the company should be able to sustain their current valuation.

OTHER INITIATIONS:

• Harris Interactive Inc (NASDAQ: HPOL) was initiated with a Buy rating and $7 target at Roth Capital. The firm believes Harris Interactive is positioned to take market share in market research as the company operates one of the largest online survey panels with more than 6 million members.
