The S&P/ASX 200 Index (ASX: XJO) enjoyed a happy hump day session this Wednesday, pushing the value of many ASX shares higher after yesterday's rough start to the short trading week.
It was a bit of a wild session for the ASX 200 today, with the index dipping into the red at one point. But investors regained their optimism, and the index finished 0.57% higher at 8,653.3 points.
This successful session for Australian investors comes after a mixed night on the American markets.
The Dow Jones Industrial Average Index (DJX: .DJI) fared decently, rising by 0.17%.
However, the tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) went the other way, dropping a chunky 0.97%.
But let's return to the local markets now and dive a little deeper into what the different ASX sectors were up to today.
