It was a bleak end to the trading week for the S&P/ASX 200 Index (ASX: XJO) and most ASX shares this Friday. After a relatively strong week until this point, investors seemed to get a bad case of cold feet today.
By the time investors went home for the weekend, the ASX 200 had dropped by a painful 0.92%, leaving the index at a flat 8,662 points.
This pessimistic session for ASX shares comes after a similarly bearish night up on the American markets.
The Dow Jones Industrial Average Index (DJX: .DJI) was in poor form, falling 0.74%.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) fared much better though, only slipping by 0.034%.
But it's time to return to the local markets and examine how today's tough trading conditions affected the different ASX sectors.
