Company: The Hershey Co

Nearly 100 protesters affiliated with the "99 Percent" populist movement disrupted General Electric's annual shareholders' meeting on Wednesday in an attack on the largest U.S. conglomerate's low tax rate.

Hershey posted a higher-than-expected first quarter profit on Tuesday, helped by price increases, and raised its full-year outlook, sending the candy maker's shares up nearly 3 percent.

As manufacturing prices rise, grocery suppliers find it harder to offer consistently low prices, now demanded by their biggest customer: Wal-Mart Stores.
