NEW YORK, June 30 U.S. stocks were set to open
little changed on Monday ahead of business activity and home
sales data, with the S&P 500 and Nasdaq Composite indexes set to
close a sixth straight quarter of gains - a streak not seen in
more than 14 years.
* The Chicago Purchasing Manager Index is due to be released
at 9:45 a.m. EDT (1345 GMT) and the National Association of
Realtors will publish its pending home sales index at 10:00 a.m.
* With an abbreviated week due to the U.S. Independence Day
holiday on Friday and a ream of data due Wednesday and Thursday,
there may be increased volatility in a market that has been
frustratingly placid for some traders.
* The S&P closed Friday 0.1 percent below its record close
set a week earlier.
* S&P 500 e-mini futures were down less than a point
and fair value - a formula that evaluates pricing by taking into
account interest rates, dividends and time to expiration on the
contract - indicated a flat open. Dow Jones industrial average
e-mini futures fell 5 points and Nasdaq 100 e-mini
futures added 2 points.
* Barring a market slide on Monday, the S&P and Nasdaq will
close up for a sixth straight quarter. That is the longest
streak of quarterly advances for the Nasdaq since 2000, while
for the S&P, it is the best run of quarters since 1998. The Dow
will close its fifth higher quarter of the last six.
* U.S. regulators on Friday approved MannKind Corp's
inhaled insulin, saying the device offered a new
treatment option for patients with diabetes. MannKind shares
jumped 12 percent in premarket trading.
* Markets will continue to keep an eye on the Middle East as
Iraqi troops battle for Tikrit after the leader of an al Qaeda
splinter group was declared caliph of a new Islamic state in
lands seized this month across a swathe of Iraq and Syria.
