The three-day run in the Dow Jones Industrial Average (INDEX: ^DJI) could come to an end today. Stocks had soared to three-month highs on a promising jobs report and hopes that the Federal Reserve and the European Central Bank could act to stimulate the economy, but futures are pointed down 0.5% before open. Asian markets were mixed overnight, while European stocks declined as Spanish 10-year yields briefly crossed the 7% mark. The Bank of England also cut back its growth forecast for the U.K. economy, and the S&P lowered its outlook on Greece to negative.

Shares of Disney (NYSE: DIS) should open slightly lower after the company beat earnings estimates after yesterday's close but fell short on revenue.

Disney was down 1.2% in premarket trading.

Shares of the fast-food chain were down more than 3% before markets opened.
