It's turning into a bit of a horror week for the S&P/ASX 200 Index (ASX: XJO) and ASX shares, with another day of selling this Wednesday.
The ASX 200 ended today's trading down a hefty 0.73% at 8,419.2 points after spending the entire session in red territory.
This woeful Wednesday for Australian investors follows a slightly more positive session for the Americans over on Wall Street this morning.
The Dow Jones Industrial Average Index (DJX: .DJI) managed to wrangle out a slight rise of 0.023%.
The Nasdaq Composite Index (NASDAQ: .IXIC) fared similarly, ticking up by 0.072%.
But let's return to ASX shares now for a look at what the different ASX sectors were up to this hump day.
