The S&P/ASX 200 Index (ASX: XJO) copped a not-so-nice sell-off this Tuesday, reversing some of the optimism that we've been seeing on the Australian markets in recent days.
The ASX 200 finished 0.69% lower by the time the closing bell rang today, leaving the index at 8,359.4 points.
This sobering session for the local markets comes despite a confident start to the trading week for American shares this morning.
The Dow Jones Industrial Average Index (DJX: .DJI) kicked off its week with a bang, gaining a rosy 0.99%.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) wasn't quite as bullish, but still rose 0.27%.
Let's get back to the ASX and check out what was happening amongst the various ASX sectors this Tuesday.
