EBAY INC. $28 (www.ebay.com) earned $529 million in the third quarter of 2015, down 8.6% from $579 million a year earlier. Per-share earnings fell at a slower pace of 6.5%, to $0.43 from $0.46, on fewer shares outstanding. Revenue declined 2.4%, to $2.10 billion from $2.15 billion. That’s partly because Google changed its search methods, which made it harder for potential buyers to find merchandise on eBay’s auction websites. Hold.
