Check out which companies are making headlines before the bell:

Wal-Mart—The retail giant said its Walmart.com site processed record orders on Cyber Monday.

FedEx—Bank of America/Merrill Lynch added the stock to its "US1" list, pointing to benefits of lower fuel prices as well as the company's profit improvement plan.

StrykerGoldman Sachs added the medical device maker to its "conviction buy" list, as part of an overall upgrade of the sector to "attractive" from "neutral." Goldman said industry profit margins are growing thanks to consolidation, and that Stryker and Hill-Rom are best positioned to capitalize on cyclical tailwinds.

Priceline Group—The travel website operator's stock was downgraded to "market perform" from "outperform" at FBR, which cites expectations of slower earnings growth.
