The S&P/ASX 200 Index (ASX: XJO) experienced a disappointing start to the trading week this Monday. After opening with a significant 0.4% loss and bouncing around in red territory all day, the ASX 200 did improve slightly by market close and ended up finishing 0.12% lower. That leaves the index at 8,624.4 points.
This rather rough start to the trading week for Australian investors comes after a more optimistic end to the American week on Saturday morning (our time).
The Dow Jones Industrial Average Index (DJX: .DJI) managed to eke out a decent 0.22% rise.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) fared even better still, gaining 0.31%.
But let's return to this week and the local markets now to check out how the different ASX sectors began their respective weeks this session.
