The zero weight to Apple was another notable relative contributor in the quarter. More recently, Apple has come under pressure from a confluence of issues ranging from a weak iPhone cycle, market share erosion in China, mounting regulatory pressure around App Store fees in Europe, and a lawsuit from the U.S. Justice Department accusing the company of anticompetitive practices in its iPhone business. All this has resulted in the stock down -11% year to date, underperforming the overall Index by -19%—Apple's worst relative performance quarter since 2013.
