Take a look at some of Wednesday's after-hours buzz:
PVH, whose brands include Calvin Klein and Tommy Hilfiger, gained nearly 6 percent in after-hours trade after the clothing line reported better-than-expected second-quarter results.
TIBCO Software rose nearly 8 percent in extended-hours trading on news that the cloud computing firm's Special Committee of independent directors has initiated a "variety of strategic and financial alternatives." August reports from The Wall Street Journal said the firm was exploring an acquisition by private-equity firms, among others.
Yum Brands fell nearly 3 percent in extended-hours trade after the fast-food conglomerate said same-store sales in China for the third quarter that ended August 31 were an estimated 13 percent lower, although sales were on the rebound. McDonald's also edged lower in after-hours trade.
Apple and its sapphire glass supplier GTAT gained slightly in after-hours trade after both fell more than 4 percent during the day on Samsung's release of two new phones and a virtual reality device.
Shoe Carnival fell more than 7 percent in extended-hours trade after the footwear retailer reported a "challenging" second quarter due to "soft" store traffic and budget-conscious consumers. While net sales increased 2.6 percent for the second fiscal quarter of 2014 year-over-year, the firm said comparable store sales fell 2.1 percent in the same time period.
Tesla shares edged higher in extended-hours trading after a report that the electric car company will open a battery factory in Nevada.
Barclays gained slightly in extended-hours trade on reports that the British financial institution will back Chinese tech conglomerate Alibaba in its IPO, expected later this month.
