Here are some of the companies with shares expected to trade actively in Wednesday's session. Stock movements noted by ticker reflect movements during regular trading hours; premarket trading is specified separately.

Johnson & Johnson -- down 1.5% premarket: A Philadelphia jury on Tuesday ordered the health-care firm to pay $8 billion in damages to a man who said his use of J&J's antipsychotic Risperdal caused enlarged breasts. It was the biggest award to date among more than 13,000 lawsuits alleging the drug caused a condition called gynecomastia in boys.

Lions Gate: The entertainment company behind the "John Wick" and "Hunger Games" franchises is considering splitting off its Starz premium cable channel into a separate company, as it looks to reduce its hefty debt load.

General Motors: The lead negotiator of the United Auto Workers said Tuesday the union was pushing the auto maker to make a firmer commitment to building vehicles in the U.S., while workers remain on a strike that has lasted more than three weeks.

Activision Blizzard: The videogame company on Tuesday suspended an esports competitor from one of its tournaments for backing antigovernment protesters in Hong Kong.
