Wells Fargo (WFC) was one big bank that traded lower following the pipeline of earnings this morning. Alexander Yokum points to tariffs as the culprit, noting the company's weaker guidance for net interest income. However, the company's investment banking sector continued to show strength. Alexander weighs Wells Fargo against other big banks to determine how it stands against its peers. Tom White offers example options trades for Wells Fargo and Goldman Sachs (GS).
