Here are the most important things to know about Thursday before you hit the door.

Apple and Facebook each beat market expectations in quarterly results released after the market closed on Wednesday, and their stocks were moving higher in after hours trading.

For Apple's fourth quarter, the company posted earnings of $3.03 per share. Analysts were expecting earnings per share of $2.83, according to estimates from FactSet. Revenue came in at $64 billion vs. the $63 billion in revenue expected.

The report contains insight into demand for the company's new iPhones. The iPhone 11 models went on sale ten days before the company's quarter ended on September 30, so the quarterly report will include 10 days worth of sales data. Investors will also be watching guidance the company gives for its key holiday season.

Facebook also beat expectations with earnings that came in at $2.12 vs. the $1.91 forecast by Refinitiv. Revenue came in at $17.65 billionvs. Refinitiv's $17.37 billionforecast.

The revenue estimate was about 27% higher than the $13.73 billion the company reported in the same quarter a year earlier.

Facebook might be facing regulatory headwinds, but the Street remains bullish on the name. Estimates compiled by FactSet show that 42 analysts have a buy rating on the stock. Five have a hold rating, and only one analyst - from Societe Generale - says to sell.

James Lee from Mizuho said the stock is one of his top picks in the US internet space, but that potentially light guidance could pressure shares after earnings are released. "We would be buyers on any weakness post-guidance," he said.

Once the Street digests Apple's and Facebook's numbers, there's a whole bunch of other earnings to get ready for.

Altria, Bristol-Myers Squibb, Estee Lauder, Fiat Chrysler, Kraft Heinz, Wayfair and Dunkin Brands are among the companies reporting earnings before the market opens.

Also reporting is backup-generator maker Generac Holdings. Shares are up 18% this month as fires and power cuts continue to plague California. CEO Aaron Jagdfeld told CNBC that demand for the company's products has increased three to four hundred percent in California, and that the power cuts caught the company "totally off guard."

Pinterest, Western Union and U.S. Steel are names to watch after the bell.
