JPMorgan analyst Harlan Sur expects shares of Micron Technology to continue outperforming following his firm's sixth consecutive positive revision to its near/mid-term "Global Memory Model." The analyst raised his estimates for Micron and expects supply of DRAM to remain tight/balanced through 2018. While average selling prices should return to typical sequential declines later in the year, Micron will likely drive margins higher in 2018 on continued cost reductions in NAND and DRAM, Sur tells investors in a research note. The analyst maintains an Overweight rating on the shares with a $60 price target.
