The weakness in tech is the biggest concern Tom White has heading into Tuesday's trading session, noting the tech-heavy Kospi index in South Korean seeing a huge overnight decline. "Watch the chips today," says Tom, as momentum in names like Nvidia (NVDA), Micron (MU), and AMD Inc. (AMD) have power to dictate market moves. Earnings season began with a double miss in JPMorgan Chase (JPM) despite strength in the big bank's equity trading business. Tom discusses how CEO Jamie Dimon added color to the company's report. Meanwhile, Wells Fargo (WFC) posted mixed earnings while Goldman Sachs (GS) beat.
