Stock futures extended Thursday's selloff into Friday's session after U.S. retail sales came in far weaker than expected and producer prices unexpectedly declined. 

S&P 500 futures were down 0.26%, Dow Jones Industrial Average futures fell 0.3%, and Nasdaq futures slid 0.41%.

Retail sales in October climbed just 0.1%, the Commerce Department said Friday. Economists had expected a far-stronger reading of 0.3%. Excluding volatile items such as gas and automobiles, sales rose 0.3% over the month. September sales were revised down to a flat reading from a previous reading of 0.1% growth. 

U.S. producer prices dropped 0.4% in October, likely a result of lower sales at retailers. Economists had expected the measure to climb 0.2%. Excluding volatile items, core prices fell just 0.1%. 

Energy stocks sold off on Thursday after weekly data on inventories rose faster than expected. Prices have been under pressure for a year as weakening global demand exacerbates continued oversupply. Separately, debate over whether the Federal Reserve would hike interest rates in December continued. The odds are greater on a December rate hike after a stellar October jobs report supported the case for tighter monetary policy. 

J.C. Penney (JCP) - Get Report slid 4% in premarket trading despite a better-than-expected quarter and raised guidance. The retail chain reported a loss of 47 cents a share, 8 cents narrower than expected, while revenue jumped 5% to $2.9 billion and beat by $20 million. 

Mylan (MYL) - Get Report shares were more than 7% higher in premarket trading ahead of the drugmaker's deadline Friday morning to have its $26 billion hostile bid for Perrigo (PRGO) - Get Report accepted. The bid will likely be rejected as only a small number of shareholders have agreed to exchange their stakes. 

Yum! Brands (YUM) - Get Report climbed more than 4% after reporting that same-store sales in China rose 5% in October. The owner of Taco Bell and KFC has suffered weaker sales in the key region after a food safety scandal last year. The restaurant chain owner maintained its fourth-quarter forecasts.  

Cisco (CSCO) - Get Report slid 5% before the bell after the networking giant issued weaker-than-expected guidance. The company anticipates sales growth of flat to 2% in its current quarter, short estimates of 5% growth. Cisco forecast adjusted earnings of between 53 cents and 55 cents a share, which are below expectations. CEO Chuck Robbins said the lower guidance reflected lower-than-expected order growth and a stronger U.S. dollar. 

Applied Materials (AMAT) - Get Report climbed 4% in premarket trading after reporting a 31% increase in profit during its recent quarter. The manufacturer of tools used in semiconductor plants said a smaller income-tax charge helped improve quarterly margins. 

Fossil (FOSL) - Get Report shares slumped 14% after disappointing fourth-quarter guidance. The accessories retailer said it expects current-quarter sales down between 16% and 7% and full-year sales down by as much as 10.5%. The company said sales would be "significantly negatively impacted" by a strong U.S. dollar and restructuring costs. Fossil also reached a deal to buy Misfit, a wearable technology company, for $260 million.

Nordstrom (JWN) - Get Report shares tumbled 16% after missing profit and sales estimates in its third quarter. The retailer earned 42 cents a share, well below forecasts of 73 cents a share, while sales of $3.2 billion came in $200 million short. 

El Pollo Loco (LOCO) - Get Report fell 7% after reducing its full-year earnings guidance. The fast-food chicken chain expects earnings og no higher than 69 cents a share, down from a previous range as high as 71 cents.
