Midday movers: DuPont, PepsiCo, Caterpillar & more

Take a look at some of Tuesday's midday movers from CNBC's Delivering Alpha conference:

DuPont jumped after Nelson Peltz said Trian Fund Management is amassing a large stake in the Dow component. Separately, Peltz said he wants PepsiCo to acquire Mondelez for $35 to $38 a share and has talked to Pepsi's management. Peltz said he also wants PepsiCo to spin off the beverage business after buying Mondelez.

Caterpillar declined after the heavy-equipment maker became the latest company to be on the hit list of founder and managing partner of Kynikos Associates Jim Chanos.

"The bulls expect a capex decline in mining. But here's the problem: they expect it to decline slowly," Chanos said.

During the Delivering Alpha conference last year, Chanos shorted Hewlett-Packard.

Leon Cooperman of Omega Advisors highlighted his 10 picks, including Qualcomm, Sandridge Energy, Express Scripts and Thermo Fisher Scientific, sending shares higher.

Meanwhile, hedge fund manager Mark Kingdon of Kingdon Capital said he likes biopharmaceutical company Aegerion Pharmaceuticals. He also favors Japanese auto companies Mazda, Fuji Heavy and Toyota.
