Take a look at some of Friday's midday movers:
Arista Networks - The networking-equipment vendor rose in its market debut after pricing 5.25 million shares at $43.
Caesars Entertainment - The gambling resort fell after Bloomberg News reported it received a notice of default from a bondholder group.
Consol Energy - The producer of coal and natural gas climbed after Goldman Sachs upgraded the stock to buy while increasing its price target to $55 from $49.
eBay - The online auctioneer declined after RW Baird commented on slowing growth in the last two weeks of May, which it said could suggest risk to second-quarter guidance. It reduced its price target $2 go $63 a share.
