It was a wild and woolly start to the short trading week for the S&P/ASX 200 Index (ASX: XJO) and most ASX shares this Tuesday.
After an initial plunge this morning, the ASX 200 managed to recover and stay in green territory for much of the session. However, a last-minute selling spree resulted in the index recording a 0.12% loss by the time the closing bell rang, leaving it at 8,399.1 points.
This bumpy Tuesday for the Australian market follows a mixed session over on Wall Street to kick off the American trading week this morning.
The Dow Jones Industrial Average Index (DJX: .DJI) was in fine form and rose 0.65%.
However, the tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) had a meltdown, tanking by a horrid 3.07%.
Let's return to the local markets now and examine how the different ASX sectors handled today's bumpy trading conditions.
