NEW YORK (TheStreet) -- Here are 10 things you should know for Friday, July 31:

1. -- U.S. stock futures were heading lower on a big day for oil and gas company earnings reports, including Chevron (CVX) - Get Report and Exxon Mobil (XOM) - Get Report.

European stocks

 were little changed on Friday amid a drop in U.K. consumer confidence and a mixed bag of corporate earnings on the last trading day of July. British broadcaster



rose on a vote of confidence from its largest shareholder.

In London, the FTSE 100 inched up 0.15%, while in Frankfurt, the DAX added 0.05%. In Paris, the CAC 40 nudged 0.36% higher.

Asian stocks were mostly higher, with Hong Kong's Hang Seng adding 0.56% and the Nikkei moving up 0.36% in Tokyo. The exception was China, where the Shanghai Stock Exchange Composite Index retreated 1.13%.

2. -- The economic calendar in the U.S. on Friday includes Chicago PMI at 9:45 a.m. and University of Michigan consumer sentiment numbers at 10 a.m.

3. -- U.S. stocks on Thursday were mixed and flattish as investors faced up to the fact that the Federal Reserve will get around to raising rates some time.

The Dow Jones Industrial Average (DIA) - Get Report sagged 0.03% to 17,745.98. The S&P 500 (SPY) - Get Report closed level at 2,108.63. The Nasdaq (QQQ) - Get Report edged higher by 0.33% to 5,128.79.

4. -- The International Monetary Fund may not be taking part in Greece's latest bailout, according to a report in the Financial Times. Greece has high debt and hasn't made many of the reforms that were conditions of a bailout, and the IMF suggested that Greece didn't meet its lending criteria anymore.

The IMF will table the issue of whether it will lend to Greece until later in the year or possibly 2016, although its staff will take part in Greek bailout negotiations.

If the IMF won't lend to Greece, it throws the country's debt deal into doubt, as Germany has said it wouldn't support a bailout for Greece without IMF participation.

Although Greece said it wants to stay on the euro, it also said it had made a "Plan B" in case it is forced out.

5. -- LinkedIn (LNKD) stock was down 7.4% in premarket trading after falling 2% on Thursday. The business-focused social network reported earnings on Thursday, saying it had boosted revenue by 33% to $711.7 million in the quarter, compared to a year ago, with adjusted earnings of 55 cents a share. Analysts had expected 30 cents per share on revenue of $679.8 million, according to Reuters.

Still, LinkedIn posted a loss of $67.7 million, or 53 cents a share, up from $1 million, or 1 cent a share, a year ago.

Investors clearly weren't too pleased with the results, although it wasn't exactly clear why. Revenue estimates for the third quarter were for $745 million to $750 million, according to LinkedIn, higher than Wall Street's estimate of $744 million. The third-quarter earnings forecast also matched analyst estimates.

6. -- New initial public offerings are afoot for fitness company SoulCycle, which filed IPO paperwork on Thursday, as well as for gym Planet Fitness and healthy snack company Amplify Snack Brands. Next week, Planet Fitness and Amplify are expected to price their IPOs. The three companies are part of a consumer push toward healthier lifestyles. 

7. -- Gold prices are hitting five-year lows as investors face the music that the Federal Reserve will raise rates in the next few months. December gold futures are now at $1,088 a troy ounce. The stronger dollar didn't help matters.

Gold provides stability for investors, but it doesn't pay dividends. With higher interest rates, bonds seem to be looking more attractive than gold for many investors.

8. -- Whole Foods (WFM) stock is down 0.75% in premarket trading after falling 11.6% on Thursday. The natural-foods grocer posted disappointing earnings and reduced its sales forecast on Wednesday. The company's plan to open five lower-cost stores under the 365 brand name didn't encourage investors that the company's future is rosy, though. The first five stores will open in 2016, with another five in 2017, the company said.

The first 365 by Whole Foods Market store will open in Los Angeles' Silver Lake neighborhood, with more to follow in Bellvue, Wash.; Houston; Portland, Ore.; and Santa Monica, Calif.

9. -- The average 30-year mortgage rate in the U.S. is now below 4%, according to data from mortgage company Freddie Mac (FMCC) . For 15-year mortgages, the average rate is 3.17%. The rates have matched the drop in the 10-Year Treasury bond, which has seen falling yields as investors fled to safety during the recent drops in the stock market.
