The S&P/ASX 200 Index (ASX: XJO) endured another rough day of trading this Tuesday, making the trading week so far a bit of a downer.
After getting a walkback from investors yesterday, the ASX 200 continued to fall over today's session. The index shut up shop at 8,255.6 points this afternoon, a fall worth 0.13%.
This unhappy Tuesday for the Australian markets comes despite a far more upbeat start to the week's trading for American investors up on Wall Street this morning.
The Dow Jones Industrial Average Index (DJX: .DJI) had a very nice start to the week indeed, rising 0.69%.
The Nasdaq Composite Index (NASDAQ: .IXIC) was a little more subdued though, and only ended up crawling 0.062% higher.
But let's get back to the ASX now and check out what was happening amongst the various ASX sectors this session.
