Lynx Equity Strategies analysts KC Rajkumar and Jahanara Nissar tell investors in a research note that Micron's (MU) "impressive" climb to the mid-$40 levels since its earnings report is powered by three factors, including the easing of Huawei restrictions, a supply outage at Toshiba's (TOSBF) Yokkaichi fab and Japan trade restrictions of exports to South Korea of some essential raw materials used in semiconductor manufacturing. The analysts say that some of the additional factors "may have played out," and, noting headline risk to Micron as a "complex" earnings season approaches, have caused them to consider taking profits.
