NEW YORK (TheStreet) -- After a strong start to the week, stocks are roughly flat on Tuesday, as investors look for more clarity on a potential Greek debt deal.
Financial stocks continue to trade well, especially with renewed discussions of a possible interest rate hike coming in September. On CNBC's "Fast Money Halftime Report," Pete Najarian, co-founder of optionmonster.com and trademonster.com, pointed out that JP Morgan (JPM) and Goldman Sachs (GS) are both leading the way, and he expects the sector to continue trading higher.
He also said investors will be able to handle an interest rate increase from the Federal Reserve.
Jim Lebenthal, president of Lebenthal Asset Management, previously had expected a rate hike to come in September, but he now believes it's more likely to happen in December. Jon Najarian agreed.
Najarian, co-founder of optionmonster.com and trademonster.com, added that Greek debt issues could again be at the forefront of investors' discussions come September, making it an unattractive time for the Fed to consider raising rates.
But that doesn't concern Paul Richards, head of FX, rates and credit distribution at UBS North America. Assuming U.S. economic data remains strong, Richards said, the Fed will likely hike rates twice this year - once in October and once in December.
He also made the case that Greece will get the debt deal it needs by Sunday, and it will not likely be an issue again until 2016. Germany wants Greece to stay in the eurozone in order to keep downward pressure on the euro. The dollar is likely to go higher, he added.
