NEW YORK, April 25 U.S. stock index futures
pointed to a lower open on Friday as a number of bellwether
names, including Amazon and Ford, fell following their quarterly
results, overshadowing positive numbers from Microsoft.
* Investors also continued to pay attention to intensifying
geopolitical strife after Ukrainian forces killed up to five
pro-Moscow rebels and Russia launched army drills near the
border. The actions raised fears Russian troops would invade.
Separately, local police said seven people were injured
overnight at a pro-Ukrainian checkpoint near the Black Sea port
of Odessa when an explosive device blew up.
* While the situation has taken a backseat to corporate
earnings in recent weeks, investors remain on edge over what the
potential fallout could be to any prolonged tension or violence.
Visa Inc late Thursday said U.S. sanctions on Russia were
hurting its card transaction volumes and that revenue growth
would slow further this quarter, sending shares down 3.7 percent
to $200.50 in premarket trading.
* Amazon fell 5 percent to $320 after posting a
jump in revenue, offset by sharp increases in spending.
Ford Motor Co fell 2.1 percent to $15.98
in premarket trading after first-quarter earnings missed
expectations, hurt by higher warranty costs in North America.
On the upside, Microsoft Corp's earnings topped
analyst forecasts, while investors were cheered by the software
giant's new emphasis on mobile and cloud computing. Shares rose
1.5 percent to $40.46.
* S&P 500 futures fell 6.2 points and were below fair
value, a formula that evaluates pricing by taking into account
interest rates, dividends and time to expiration on the
contract. Dow Jones industrial average futures fell 51
points and Nasdaq 100 futures fell 13.75 points.
* For the week, the Dow is up 0.6 percent, the S&P
is up 0.7 percent and the Nasdaq is up 1.3
percent. It is the second straight week of gains for all three,
boosted by strong results, especially from high-profile names
like Apple Inc and Caterpillar Inc.
* While companies are clearing a lowered bar, estimates have
been improving. Profits are now seen rising 2.9 percent this
quarter, down from the 6.5 percent growth rate estimated at the
start of the year, but above the low of 0.6 percent seen last
week, according to Thomson Reuters data.
* Whirlpool Corp reported adjusted earnings that
rose from the prior year, and revenue that was up 4.7 percent.
* According to sources familiar with the matter, Allergan
Inc approached Shire Plc in recent months about
a possible takeover but was rebuffed, in the latest example of a
U.S. drugmaker seeking to buy an overseas rival to lower its tax
