LSI (LSI-OLD +1%) edges higher on a down day after Barron's suggests the chipmaker could rally 50% (on top of its 31% YTD gain) on the back of strong demand for its hard drive and solid-state drive (SSD) controller chips - this market is dominated by LSI and MRVL. The growing adoption of cloud storage (I, II) is seen as a positive for LSI, as is a forward P/E of 10, a strong balance sheet, and improving margins.
