NEW YORK (TheStreet) -- Here are 10 things you should know for Thursday, July 30:

1. -- U.S. stock futures were sinking as investors take in the GDP number Thursday morning and digest that the Federal Reserve didn't raise interest rates Wednesday.

European stocks had a good start Thursday with a raft of earnings announcements in London and elsewhere and despite the volatility in Asia.

In London, the FTSE 100 was up 0.61%, while in Paris, the CAC 40 was up 0.55%. In Frankfurt, the DAX was up 0.45%.

Asian stocks were mixed, as the the Nikkei 225 closed up 1.08%, while in Hong Kong, the Hang Seng was down 0.49%. The Shanghai Composite was down 2.20%.

2. -- The economic calendar in the U.S. on Thursday includes gross domestic product numbers at 8:30 a.m. and jobless claims numbers, also at 8:30 a.m.

3. -- U.S. stocks on Wednesday rallied as the Federal Reserve's Open Market Committee declined to raise interest rates immediately.

The Dow Jones Industrial Average (DIA) - Get Report rose 0.69% to 17,751.39. The S&P 500 (SPY) - Get Report jumped 0.73% to 2,108.57. The Nasdaq (QQQ) - Get Report increased 0.44% to 5,111.73.

4. -- The U.S. Bureau of Economic Analysis said GDP was 2.3% for the second quarter of the year. Economists surveyed by Econoday had estimated that GDP will be at 2.9%, although estimates varied widely from 1.9% to 3.5%. In the first quarter, GDP contracted by 0.2%.

The not-bad but lower-than-expected GDP number might discourage the Fed from raising interest rates sooner rather than later.

5. -- Royal Dutch Shell (RDS.A) reported earnings Thursday, saying that its profits fell sharply in the quarter due to lower oil prices. The company also said it would lay off 6,500 workers and cut expenditures as cost-saving measures. 

Shell said its adjusted earnings were $3.8 billion, starkly lower than the $6.1 billion for the same quarter in 2014. Its average revenue from oil was 48% lower from the year-ago quarter; natural gas revenue was down 31% over the same time frame.

The company also rejected criticism that its $70 billion April acquisition of BG (BRGYY) was too expensive or badly timed.

In European trading, Shell was rising by 5.6%.

6. -- Shares in the social network Facebook (FB) - Get Report were falling by 2.3% in premarket trading after the company presented  a second-quarter earnings beat that didn't impress investors. Revenue grew by 39%, but expenses grew even more.

The company booked earnings of 25 cents a share, or $719 million total, a drop of 9.1% from the year-ago quarter, when Facebook earned 30 cents a share, or $791 million. Facebook said that it would have earned 50 cents a share if it did not have certain expenses. Analysts were expecting adjusted earnings of 47 cents a share.

Revenue was up 39% to $4.04 billion in the quarter, a rise from $2.91 billion in the quarter a year ago and beating analyst estimates of $3.99 billion. But costs rose 82% from a year ago.

Facebook's daily active users were up by 17% year over year to 968 million, with a 29% jump in daily active users on mobile to 844 million. The company had 1.49 billion monthly active users in June 2015, it said, a rise of 13% from June 2014.

7. --  The Department of Labor reported that there were 267,000 initial jobless claims last week. After the prior week's strong showing -- the new unemployment claim count was the lowest since 1973 -- economists consulted by Econodayhad estimated that there would be 272,000 new unemployment claims last week. The prior week's count was 255,000 new jobless claims.

Unemployment claims have fallen to very low levels by historical standards, and the unemployment rate is also low. That suggests that the labor market is good and still improving.

Low unemployment may influence the Federal Reserve to raise rates more quickly than it otherwise would.

8. -- Electric car maker Tesla (TSLA) - Get Report still won't be spending money on advertising or traditional car salespeople, but it will be starting a referral program. Owners of a Tesla car will get a $1,000 bounty if a friend orders one via a referral link, and those using the link will also save $1,000 on the car price. The first referrer in each international sales region to get 10 referrals -- that's the program maximum -- will get a free Model X, the company's new SUV.

Tesla said its cost of acquiring a sale was about $2,000, making the offer cost-neutral. Still, the price break is unusual for the company and shareholders may not be thrilled by it.

In premarket trading, Tesla stock was down by 0.31%.

9. -- The U.S. dollar got even stronger after the Fed did not raise interest rates on Wednesday but did describe the U.S. economy as fairly strong. The dollar rose against both the euro and the yen.

Bond yields also rose in response to the expectation that the Fed will raise rates in September.
