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

Amazon.com - The online retailer edged higher after saying it would let users shop via Twitter. In addition, Twitter's six-month lockup that prevents early investors from selling their shares, ends Monday.

Aaon - The maker of heating and air-conditioning equipment rose after reporting first-quarter revenue that beat estimates.

B/E Aerospace - The manufacturer of airplane components climbed after saying it might put itself up for sale.

Exxon Mobil - The oil producer and rival ConocoPhillips rose to records.

Goldman Sachs Group - The brokerage fell after a proxy advisory firm recommended shareholders vote against its executive compensation plan. It added that Morgan Stanley was also paying its executives too much.

King Digital Entertainment - The game maker gained after the three lead underwriters of its IPO started coverage of the stock with a buy rating or the equivalent.

Nordion - The Canadian medical isotope supplier rose after Sterigenics, a sterilization services provider, upped its offer after Nordion drew a competing bid from an unnamed entity.

PerkinElmer The maker of medical equipment rose after Janney upgraded it to buy.
