Stocks: 4 things to know before the open

premarket friday

It's all about Chinese shoppers and gamblers on Friday.

As the world's second biggest economy slows, Chinese are becoming more cautious about spending on luxury brands.

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

U.S. stock futures are slightly up on Friday.

1. Chinese cut down on luxury shopping: Hugo Boss (BOSSY) is the latest company to feel the pinch from the slump in China. The German fashion brand is tanking 10% in London, after cutting its sales earnings outlook due to tougher conditions in Asia.

Burberry (BBRYF) and Louis Vuitton (LVMHF) both blamed China for weaker sales earlier this week.

2. Stock market movers -- Youku Tudou, Yum Brands, Nestle, Wynn Resorts: Shares in China's online video service provider Youku Tudou (YOKU) are up 23% premarket, after Alibaba announced it wants to buy the YouTube-like site.

Yum Brands (YUM) stock rose 2.2% in after-hours trading.

Wynn Resorts (WYNN), the casino and hotels operator, is down 8.5% premarket, after its Macau division reported a net revenue decline of nearly 40% Thursday.

Nestle (NSRGF) has cut its outlook for this year, pushing its shares down 2%. The company was hit by a temporary ban on one of its most popular products, Maggi noodles, in India after reports of lead contamination. Nestle disputed the findings, and won an appeal, but the company said the affair had a "material impact."

3. Earnings and economics: Companies including General Electric (GE) and Honeywell (HON) will report quarterly earnings before the opening bell rings.

At 10 a.m. ET, the University of Michigan will release its October consumer sentiment index.

U.S. manufacturing and industrial production data will be published at 8:15 a.m. ET, giving an insight into the health of the economy.

Investors will watch the data to get a sense of how likely is it the Federal Reserve could still raise interest rates this year. The Fed didn't raise rates in September and a rate hike in October looks very unlikely. But some Fed officials still want a rate hike in 2015.

Final data confirmed consumer prices across the eurozone fell by 0.1% in September. It's the first time Europe has slipped into deflation since March, when the European Central Bank began pumping 60 billion euros ($67 billion) a month into the region's markets in an attempt to boost prices and economic activity.

4. Market overview and recap: Most world markets are gaining Friday. European markets are all up in early trading. Asian markets ended the week with a positive session.

U.S. stocks closed over 1% higher Thursday. The Dow Jones industrial average rose 1.3%, the S&P 500 was up 1.8% and the Nasdaq climbed 1.5%.
