BMO Capital analyst Ambrish Srivastava downgraded Xilinx to Market Perform from Outperform while raising his price target for the shares to $125 from $100. The chipmaker closed Friday up $1.34 to $126.64. The risk/reward is no longer at these share levels, Srivastava tells investors in a research note. The current valuation reasonably reflects the opportunity in front of Xilinx, adds the analyst. As such, Srivastava finds it hard to justify an Outperform rating.
