The VN-Index suffered its biggest one-day loss in more than two months, plummeting 3.9% on Thursday amid no apparent domestic or external news catalyst. The index has dropped six of the last eight days and is down 9.1% since hitting a record high early last week. Several of the market's high-flyers that fueled a 65% surge over the last year to the recent all-time high led today's sell-off, including VIC (-6.9%), MSN (-7.0%), PLX (-7.0%) and VJC (-6.1%).
