U.S. Steel (X) downgraded to Hold from Buy at Jefferies with analyst Seth Rosenfeld saying "poor" Q4 earnings and Q1 guides will begin to reflect the extent of recent steel margin weakness. 3. Fortinet (FTNT) downgraded to Market Perform from Outperform at BMO Capital with analyst Keith Bachman saying he is not bearish on the stock, expecting the firewall market to remain healthy for several years given the changing throughput requirements, but sees the rating change as reflective of its more balanced risk-reward. 4.
