LONDON (CNNMoney) -

U.S. stock markets are sitting at all-time highs, but can investors hope for yet another record?

U.S. stock futures were lower and European markets were soft, indicating investors may want to take a breather after the latest rally.

Here are the four things you need to know before the opening bell rings in New York:

1. Ready for GDP: The U.S. government will report a revised estimate of second quarter GDP at 8:30 a.m. ET. The first estimate showed the U.S. economy grew at a 4% annual pace, bouncing back after a harsh winter.

Data on weekly jobless claims will also be released at 8:30 a.m.

2. Earnings: Dollar General and Abercrombie and Fitch will report quarterly results before the opening bell.

Australian airline Qantas reported an annual loss of $2.6 billion, but CEO Alan Joyce reassured investors that he expected the company to rebound strongly and post a profit in the first half of fiscal 2015. Qantas shares surged 7%.

Shares in Guess were off by as much as 8% in extended trading after the company said quarterly profits were just half of what they were a year ago.

3. Potential market movers -- credit cards: Shares in both Visa and Mastercard were relatively weak ahead of the opening bell. This comes on the same day that an annual report on credit card satisfaction showed American Express and Discover were the favorite cards in the U.S.

4. Wednesday market recap: U.S. stocks closed with mixed results Wednesday. While the S&P 500 barely budged, it closed above 2,000 for the second time ever. The Dow gained 15 points and the Nasdaq edged into the red.
