Wall Street hits high on trade optimism

SOUNDBITE: MERCADIEN ASSET MANAGEMENT PRESIDENT KEN KAMEN (ENGLISH) SAYING:

"As we go into next year, the economics certainly in the United States actually look pretty strong with a strong consumer and spending looking very very well. And I think we're going to have a very good holiday season. So I think there's a lot of reason the market is being optimistic into year end."

Boeing shares declined. Its new astronaut capsule successfully launched but failed to reach the orbit it needed to get to the International Space Station.

Shares of its biggest supplier, Spirit AeroSystems dropped. The company said it'll stop making fuselages for the grounded 737 MAX jets. The company gets half of its revenue from that plane. Boeing announced this week that it'll temporarily halt production of those planes.

The biggest gainer on the S&P: Carnival. The cruise operator that's a bellwether for the industry issued a strong profit forecast for 2020.

Scholastic shares surged. Growth in its book fairs business helped the publisher post earnings that leapfrogged past Wall Street's targets.
