"In terms of the euro I think the euro is going to be pretty much sidelined. It doesn't look like anything significant is going to happen between now and the referendum," said Jason Leinwand, managing director of Riverside Risk Advisors. "I think we're going to go back at least until the fifth to a sort of fundamental focus (that) the U.S. economy is outperforming."
"I think the markets are going to discount everything that happened on Monday," he said. "The market understands it's going to be fairly significant turmoil if (Greece leaves the euro zone)."
Stocks closed mildly higher on Tuesday, with the S&P 500 eking out its narrowest gain on record for the first half of the year. The major indices plunged nearly 2 percent or more on Monday for their worst day of the year as news of a July 5 referendum in Greece negatively surprised investors.
