Stocks stumble to worst week in seven months as VIC slumps. The VN-Index fell for a fifth day in six, capping its biggest weekly loss since January. The index dropped to 622 in the afternoon, or 1.5%, before the market was able to claw back about half of that loss to close down 4.55 points, or 0.7%, to 627.39. VIC (-5.9%) was the biggest culprit as the real estate developer suffered its largest one-day drop in almost two years, extending its losses this week to 12%.
