Futures Drift, End of Quarter in Focus

Stock futures were flat to slightly lower Tuesday as the market braced for an onslaught of economic data heading into the holiday weekend.

Though Wall Street's rally has shown signs of stalling recently, investors have pushed the major averages to some impressive numbers as the month and the quarter come to an end.

The S&P 500 is up 16.2 percent for the second quarter, its best quarterly percentage gain since the final quarter of 1998. The Nasdaq (up 20.6 percent) has had its best quarter since the second quarter of 2003, while the Dow (up 12.1 percent) will chalk up its best quarter since the final quarter of 2003.

A positive day today would give the Dow, the S&P 500, and the Nasdaq gains for the month of June, marking the fourth-straight month of gains for each. The Dow, however, is still down for the year while the S&P 500 and the Nasdaq have yearly gains.

As for this morning, there's no clear indication of the market's direction either from stock index futures or the European markets. Only one report is on the economic calendar this morning, as the Conference Board issues its monthly consumer confidence index at 10 am New York time.

Investors may focus on Fed speeches Tuesday, though only one will occur during market hours. At noon, St. Louis Federal Reserve Bank President James Bullard will talk about possible Fed exit strategies from the extraordinary measures implemented to deal with the financial crisis.

Chicago Fed President Thomas Hoenig speaks at New York University shortly after 4 pm, while San Francisco Fed President Janet Yellen speaks to the Commonwealth Club of San Francisco this evening.
