Another flat week expected ahead for most US stocks

LAST week, enthusiasm about the Federal Reserve's interest rate reprieve was quickly superseded by fear of a Greek default.

Most Wall Street pundits had predicted that 2015 would mirror the pattern in 2014, a weak performance in the first half of the year followed by strength in the second half. Well, they were at least half right - with a week to go in the first half of the trading year, stocks are almost exactly where they started the year.

But the second half could be just as bad unless the outstanding issues of the "Grexit" and the timing of Federal Reserve rate hikes are soon resolved.
