Summary: U.S. markets ended Tuesday's session narrowly in the red after posting three straight days of gains. May auto sales figures from car companies came in better than many had expected. Pilgrim's Pride raised its bid for Hillshire Brands by a little more than one billion dollars to $7.7 billion. The latest bid tops the offer Tyson Foods made last week for $50 a share. Hillshire's board of directors authorized the company to consider the two competing offers. Krispy Kreme cut its full year earnings outlook. Tesla CEO told shareholders that he would likely remain with the electric car maker for at least another four years and then reassess. Ruben Ramirez reports from Wall Street.
