It was a rather horrid hump day for the S&P/ASX 200 Index (ASX: XJO) and many ASX shares today, as investor pessimism once again took over the markets.
After spending the entire session in red territory, the ASX 200 ended up closing down a nasty 1.18%. That leaves the index at 8,843.6 points at this mid-week point.
Today's unhappy performance from the Australian markets follows a similarly negative night up on Wall Street.
The Dow Jones Industrial Average Index (DJX: .DJI) closed down 0.59% after initially rising during morning trading.
In a rare coincidence, the tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) also finished up with a 0.59% loss.
But let's return to the local markets now and dive a little deeper into how today's pessimism filtered down into the various ASX sectors.
