Markets look set to chalk up another week of gains, barring surprises Friday.

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

U.S. stock futures were slightly weaker.

1. Media moves: 21st Century Fox (FOXA) has sold its satellite TV operations in Italy and Germany to BSkyB (BSYBF), raising about $9 billion in cash as it stalks Time Warner (TWX).

2. Sanctions talk: EU ambassadors meet for a second day running to talk about how to escalate sanctions on Russia over Ukraine. A decision is not expected until next week. Russian stocks were down 1%, extending their losses for the year. German business confidence fell for a third month in a row as geopolitical tensions continued to take their toll.

Most European markets were weaker in early trade, although robust U.K. GDP data helped keep the FTSE 100 steady.

Asian markets ended the week mixed. Japan's Nikkei and China's Shanghai Composite both rose about 1%. Stocks in Kuala Lumpur fell as investors remain cautious after a Malaysia Airlines flight crashed last week, leaving the airline's future in the balance.

3. Company earnings: AbbVie (ABBV) will report earnings before the opening bell. The pharmaceutical company announced last week that it will merge with a company based in the United Kingdom as a way to slash its tax bill.

4. Stock market movers -- Amazon, Yahoo, Facebook: Shares of Amazon (AMZN) fell nearly 10% in premarket trading after the company posted a larger than expected loss. Yahoo (YHOO) and Ebay (EBAY) were also weaker. Facebook (FB) gained nearly 0.7% after hitting an all-time high Thursday on bumper earnings.

5. Argentina default? Time is running out for Argentina to avoid defaulting on its debt as another attempt to broker a deal with bondholders failed Thursday.

6. Market recap: U.S. stocks barely budged Thursday, ending the day mixed. The S&P 500 closed only about one point higher, but that was enough to notch another all-time high. The Dow Jones Industrial Average and the Nasdaq both dropped slightly.
