SanDisk (SNDK +2.6%) and Micron (MU +1.6%) are adding to their 2013 gains after rival memory giant Samsung provided a Q3 op. profit guidance range whose midpoint is above analyst estimates.
Samsung, whose full results arrive later this month, has been expected to report strong numbers for its DRAM/NAND flash ops, thanks to strong mobile demand and a favorable supply/demand balance that got better following a massive fire at a Chinese SK Hynix DRAM fab.
Several other chipmakers with strong mobile exposure, some of whom are major suppliers to Samsung's mobile device unit, are also rallying: SYNA +4.4%. OVTI +3.6%. SWKS +3.2%. RFMD +2.7%. ANAD +2.5%.
