Take a look at some of Wednesday's midday movers:

Post Holdings spiked on a Dow Jones report that it was the likely winner in an auction for Michael Foods. Tyson Foods moved lower on the news.

SodaStream International moved higher on a report by Israeli financial daily Calcalist that the company was in talks to sell up to a 16 percent stake. Pepsico, Dr Pepper Snapple Group and Starbucks were among the reported suitors.

Yamana Gold and Agnico Eagle Mines both fell after they announced a deal to acquire Canadian miner Osisko Mining for $3.5 billion, topping an 11 percent hostile bid offer by Goldcorp.

Yelp rose after Citi upgraded the stock to buy from neutral with a price target of $76, citing valuation.

King Digital Entertainment gained ground after announcing the launch of Candy Crush Saga in China. The stock is down about 20 percent from its IPO price.

General Motors moved higher. The auto manufacturer said it will ask a bankruptcy court to bar plaintiffs from proceeding with lawsuits against it for claims related to any actions before it filed for bankruptcy in 2009, indicating a tougher position towards suits tied to its recent recall over faulty ignition switches.

Interactive Brokers Group advanced after the brokerage reported better-than-expected first-quarter earnings and revenue.

ASML Holdings slid after the supplier of computer chips trimmed its guidance for the second quarter, reflecting lower demand.

Johnson Controls rose on news the auto parts maker would buy Air Distribution Technologies for $1.6 billion. Air Distribution makes air ventilation products used in buildings.

Moelis moved higher in its market debut after the boutique investment bank offered 6.5 million shares at $25, below the expected price range.

Regeneron Pharmaceuticals gained ground after Canaccord began coverage with a buy rating and $350 price target, saying the biotech has an "industry-best pipeline".

Energy stocks remained on fire. Schlumberger, Halliburton, Devon Energy, Hess, and Newfield Exploration all hit 52-week highs.

Lockheed Martin moved higher. The Defense Department approved the first trans-Atlantic flight of Lockheed's F-35 fighter jet.
