The S&P/ASX 200 Index (ASX: XJO) endured a red hump day session this Wednesday, continuing on the selling momentum we have seen for three days in a row now. After a big drop this morning, the ASX 200 managed to regain some ground over the day, but ended up closing 0.46% lower by the time trading wrapped up. That leaves the index at 8,630.4 points.
This disappointing mid-week session for Australian investors comes after a mixed night over on Wall Street.
The Dow Jones Industrial Average Index (DJX: .DJI) recovered from an early dip to post a 0.11% gain.
However, the tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) wasn't so lucky and ended up dropping 0.71%.
Let's get back to ASX shares now, though, and take a deeper dive into what was going on amongst the different ASX sectors today.
