US Top Rating Updates on 12/22: JEF, COUP, BSX, COO and More

Keefe Bruyette analyst Michael Brown downgraded $Jefferies Financial(JEF.US)$ to Market Perform from Outperform with a price target of $37, down from $38. Jefferies faced a tough operating environment in Q4 due to weaker than expected equity capital markets and advisory revenues as well as a higher comp ratio, Brown tells investors in a research note.

Canaccord analyst Joseph Vafi downgraded $Coupa Software(COUP.US)$ to Hold from Buy after the company entered into a definitive agreement to be acquired by Thoma Bravo for $81 per share that he says was "thoroughly shopped."

Mizuho analyst Anthony Petrone initiated coverage of $Boston Scientific(BSX.US)$ with a Neutral rating and $52 price target. The analyst believes Boston Scientific's portfolio mix toward critical care products "should be a safe recession hedge." However, he views the stock's valuation as full at current levels.
