It was an interesting and historic day for the S&P/ASX 200 Index (ASX: XJO) this Wednesday. At market open, the ASX 200 was straight out of the blocks, rising as much as 0.6% and hitting a new all-time record high of 8,639.1 points soon after.
But investors cooled their jets over the rest of the day, with the index closing at 8,592.1 points, up a far tamer 0.057%.
This momentous day for Australian investors comes after a positive session up on the American market overnight.
The Dow Jones Industrial Average Index (DJX: .DJI) put on a solid show, rising 0.25%.
The tech-heavy Nasdaq Composite Index (NASDAQ: .IXIC) fared slightly better, gaining 0.63%.
