"Just when you thought it was safe to go back in the water," said Art Hogan, chief market analyst at Wunderlich Securities. "The problem with this is during the momentum new tech sell off, some of the old techs were catching a bid and that investor psychology of buying reasonable valuation was working its way into the old technology names. I'm not sure what happens now."

"On balance two household names blew up – IBM and J.P. Morgan – I think it's a hurdle we can get over but it's certainly a bump in the road," said Hogan. "I don't think it's a pivotal point or a reversal that's going to put us in a tailspin like something like Ukraine could." J.P. Morgan reported earnings that missed the mark last Friday.
Ukraine was also in the headlines Thursday. Secretary of State John Kerry meets in Geneva with foreign ministers from Ukraine and Russia. EU officials also are attending.
"That's the one thing that can usurp things," Hogan said of Ukraine.
