Before the bell 06-05-06: GOOG, MSFT, YHOO, EBAY

Stocks are set to open lower this morning based on a look at futures trading. The main culprit  is rising oil. Iran is threatening the "energy flow in this region" if the United States doesn't stop trying to curtail its nuclear activity. Plus, the Wall Street Journal reports that Saudi Arabia is trimming oil exports since refining demand is down. Both factors are driving up the price of oil to $73.50 this morning.

A measure of the health of the service sector, the Institute for Supply Management's May services index, will be reported this morning. Growth is expected to slow from last month's reading of 63.

While a lower reading would mean the Fed may not have to raise interest rates at its next meeting late this month, it could also worry investors that the economy is slowing  sharply. Last Friday's job report was much weaker than expected, raising such concerns. The AP reports this morning, "Economy Might Be Heading for Tough Times."
