Intel (NASDAQ: INTC), down 10%; Boeing (NYSE: BA), down 8%; and Amgen (NASDAQ: AMGN), off by 4%. For perspective, last month the Dow Jones Industrial Average overall gained a little less than 3%. That trio is a curious mix. Usually, there’s at least a semi-clear common thread among the big names logging the worst losses. But, there aren’t many similarities between a chipmaker, an aircraft manufacturer, and a pharmaceutical outfit. There is one common element among these Dow laggards, however: Their recent share price weakness is attributable to disappointing quarterly reports that portend trouble ahead. Intel’s first-quarter numbers weren’t terrible. Revenue fell 1% year over year, and operating profits slumped by 6%. Given the challenging, turbulent environment created by the pandemic, however — and the fact that earnings of $1.39 per share soundly trounced estimates of $1.15 — those results could be considered a victory.
