Has the summer stupor kicked in? Markets are looking flat Friday, and there are no World Cup matches to provide a distraction.

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

1. Potential market movers -- Nike, GE: Shares in Nike were rising by about 3% premarket after the company's earning beat Wall Street's expectations.

General Electric was another premarket mover Friday, with shares down by about 1%. The company recently agreed to buy Alstom's power generation business.

2. Economic announcements: The University of Michigan will report its consumer sentiment index at 9:55 a.m. ET.

3. Calm before the weekend: U.S. stock futures were very slightly lower ahead of the open, continuing the recent trend of modest moves. U.S. stocks closed slightly lower Thursday. The Dow Jones Industrial Average and S&P 500 ended the day in the red, while the Nasdaq finished flat.

Oil and gold were little changed too.

CNNMoney's Fear & Greed index shows investors are still feeling very greedy.

4. Mid-year report: So far this year, stock market performance has been impressive.

After a significant drop in January, all three major U.S. indexes have gone on to new record highs. The S&P 500 has surged by nearly 6%, the Nasdaq is up by almost 5% and the Dow has risen by 1.6%.

5. International markets in positive territory: European markets were edging up in early trading.

In Asian markets, the Nikkei in Tokyo was a standout performer as it fell by 1.4% Friday. The other key indexes were mixed.
