It was a wild and ultimately red session for the S&P/ASX 200 Index (ASX: XJO) and many ASX shares this Wednesday. After yesterday's gains, investors were far more cautious today, with the ASX 200 spending time in both positive and negative territory. The bears won out, though, with the index closing at 8,727.7 points, down 0.092%.
This disappointing midweek session for the Australian markets comes after a more upbeat morning on the US markets.
The Dow Jones Industrial Average Index (DJX: .DJI) overcame some early jitters to finish 0.18% higher.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) was a little more decisive, rising 0.45%.
But let's return to the local markets now and examine how today's trading conditions filtered down into the various ASX sectors this hump day.
