It was a horror start to the trading week for the S&P/ASX 200 Index (ASX: XJO) and many ASX shares.
After ending what was a pretty sad week on a sour note last Friday, investors seemed to come back from the weekend with even colder feet. After opening with a significant drop, the ASX 200 ended the trading day with a nasty 1.45% fall. That leaves the index at just 8,505.3 points.
This horrid start to the Australian trading week follows a similarly pessimistic end to the American week on Friday night (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) was in a bit of a panic, finishing down 1.07%.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) fared even worse, dropping 1.54%.
But let's get back to this week and the local markets now, with a deeper dive into what was happening amongst the various ASX sectors today.
