Marvell Technology (MRVL) shares are sliding after earnings as volatility in semiconductor stocks continues into the end of the week. Kim Forrest of Bokeh Capital says investors were disappointed by revenue and guidance tied to the company’s partnership with Alphabet (GOOGL). Meanwhile, Morningstar’s William Kerwin says he liked the report and believes Marvell is “firing on all cylinders,” calling Friday’s sell-off a buying opportunity.
