It was a happy hump day for the S&P/ASX 200 Index (ASX: XJO) and many ASX shares this Wednesday, as investors continue to bask in worldwide market optimism.
After yesterday's close call and slight rise, investors were more decisive today, sending the ASX 200 up a confident 0.54%. That leaves the index at 8,966.3 points, its highest level in two months.
This optimistic midweek session for Australian shares follows a mixed night on the American boards.
The Dow Jones Industrial Average Index (DJX: .DJI) was on fire, gaining 0.64% after hitting a new record high.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) wasn't so lucky, though, and fell 1.15%.
But let's return to the local markets now and examine what was going on amongst the various ASX sectors today.
