U.S. HOT STOCK FUTURES: HOT STOCKS TO WATCH

Among the companies with shares expected to actively trade in Monday's session are Onyx Pharmaceuticals Inc. (ONXX), Nokia Corp. (NOK, NOK1V.HE) and Acura Pharmaceuticals Inc. (ACUR).

Onyx Pharmaceuticals said it is seeking potential buyers after rejecting an unsolicited acquisition offer from Amgen Inc. (AMGN) of around $8.7 billion, based on shares outstanding, potentially setting the stage for a bidding war for the cancer-drug developer. Amgen's bid valued the biotech company at $120 a share, or about 38% more than its closing price Friday of $86.82. Onyx shares jumped 50% to $130.25 premarket.

Nokia signaled an end to its tie-up with Siemens AG (SI, SIE.XE), announcing a 1.7 billion euro ($2.2 billion) deal to buy its German partner out of the two companies' telecom equipment joint venture Nokia Siemens Networks. Nokia will pay EUR1.2 billion in cash for Siemens's 50% stake when the deal is completed in the third quarter and NSN will become a wholly-owned unit of Nokia, subject to regulatory approval. The balance will be paid in the form of a secured loan from Siemens due a year later. Nokia's American depositary shares rose 7.2% to $4.01 premarket.

Acura Pharmaceuticals said that Pfizer Inc. (PFE) will expand commercialization of a pain drug that uses the specialty pharmaceutical company's tamper-resistant technology. Acura has exclusively licensed its Aversion technology to Pfizer in the U.S., Canada and Mexico for use in Oxecta, an immediate-release oxycodone with a tamper-resistant design that inhibits recreational use of the drug. Acura receives tired royalties ranging from 5% to 25% on net sales of Oxecta. Shares rose 23% to $2.32 premarket.

InterDigital Inc. (IDCC) said an administrative law judge overseeing patent-infringement claims against Nokia, Huawei Technologies Co. and ZTE Corp. (ZTCOY, 000063.SZ, 0763.HK) found that one of the wireless-technology company's patents were infringed but that the patent was invalid and that another six patents weren't infringed. InterDigital's shares sank 18% to $36.53 premarket.
