The S&P/ASX 200 Index (ASX: XJO) once again recorded a heavy loss for this Wednesday's trading session, entering official correction territory and further exacerbating the market sell-off we've been witnessing for the past month or so.
The ASX 200 quickly plunged upon market open and stayed in negative territory all day, closing with a 1.32% loss. That leaves the index at 7,786.2 points.
This horrid hump day for the Australian markets comes after a rough night up on the American markets this morning.
The Dow Jones Industrial Average Index (DJX: .DJI) was a horror show, dropping 1.14% lower.
Things were better on the Nasdaq Composite Index (NASDAQ: .IXIC) though, which only dipped by 0.18%.
But let's return to the ASX for a look at the performances of the different ASX sectors this session.
