NEW YORK (TheStreet) -- Here are 10 things you should know for Friday, March 27:
1. -- U.S. stock futures were sinking Friday at the end of a harsh week on the market. Investors will look to GDP and consumer sentiment numbers today.
European stocks were mixed Friday, with London's oil-and-resources-heavy FTSE 100 slipping back, while continental markets seemed to be recovering some of Thursday's losses. Airlines did well.
2. -- The economic calendar in the U.S. on Friday includes Gross Domestic Product numbers at 8:30 a.m. The Bureau of Economic Analysis presents corporate profit data at 8:30 a.m. The University of Michigan's consumer sentiment index comes in at 10 a.m. Federal Reserve Chair Janet Yellen speaks on monetary policy at the San Francisco Fed at 3:45 p.m.
3. -- U.S. stocks on Thursday closed down after a volatile day in the markets, and despite a drop in unemployment.
4. -- Danish drugmaker Novo Nordisk (NVO - Get Report) will try again to bring its new type of insulin, Tresiba, to the U.S. market. The company said Friday it would resubmit the drug to the Food and Drug Administration within a month. The FDA rejected the long-acting insulin two years ago over concerns about heart attack and stroke risk. Tresiba is already available in Europe and elsewhere.
Novo Nordisk is the world's largest producer of insulin. The company hopes to sell Tresiba in the U.S. market by 2016.
In premarket trading, Novo Nordisk U.S. ADRs were up 3.23%, although the stock itself was up more than 13%.
5. -- In a shakeup in the fizzy drink business, PepsiCo's (PEP - Get Report) flagship Pepsi outsold Coca-Cola's (KO - Get Report) Diet Coke as the second-most popular carbonated drink in the U.S. Coca-Cola hung on to the top spot.
Beverage Digest said that sales of Coke's sugar-free Diet Coke fell 6.6%, and Diet Pepsi sales fell 5%. Energy drinks, cold coffee, and especially bottled water were growth areas for the beverage industry. Bottled water sales grew 9% in 2014, aiding Nestle (NSRGY). Consumers have been looking away from high-calorie beverages but have also been shying away from aspartame-sweetened drinks over health concerns.
Both Pepsi and Coca-Cola stocks were flat in premarket trading.
6. -- "Everything store" Amazon (AMZN - Get Report) was reported to be in talks to buy Net-a-Porter, an online luxury-clothing seller, from its Swiss owner, Richemont (CFRHF). Women's Wear Daily and Forbes reported that the companies are in early-stage talks for Amazon to buy London-based Net-a-Porter for €2 billion ($2.2 billion) or less. The deal could expand Amazon's high-fashion business.
Richemont bought Net-a-Porter for €392 million in 2010. If Amazon does pay in the ballpark of $2 billion, this would be the company's largest acquisition.
In premarket trading, Amazon was off slightly by 0.01%.
7. -- The payday loan market may be reshaped, as President Obama said he wanted new limitations on the short-term, high-interest loans. Although Obama is unlikely to get cooperation from a Republican-led Congress, he will probably push the changes via the Consumer Financial Protection Bureau.
8. -- Google (GOOG - Get Report) (GOOGL - Get Report) will pay its incoming CFO, Ruth Porat, $70 million. Porat, who is leaving Morgan Stanley (MS - Get Report) for her new job, will start off with a $5 million signing bonus and $25 million stock grant than vests in 2017. She will also receive $40 million in stock grants in 2016 and a salary of $650,000, Google reported in a regulatory filing.
In premarket trading, Google's GOOG share class was down 0.39%.
9. -- Oil prices have been propped up by an emerging war in Yemen, although oil was falling early Friday. Conflict in Yemen may mire Iran and Saudi Arabia in a war and disrupt oil delivery routes.
West Texas Intermediate crude oil was trading above $50 a barrel.
10. -- New U.S. jobless claims were fewer than expected, the government reported on Thursday. Despite bad weather and a strong dollar, initial unemployment claims fell to 282,000 for last week. Analysts had expected 290,000.
The mixed economic news -- lower unemployment, but softening manufacturing and consumer spending -- will have an uncertain effect on when the Federal Reserve opts to raise interest rates.
