At 11:40am, the S&P/ASX 200 is 0.23 per cent higher at 8,140.50.
This comes amid expectations of a significant 50 basis point interest rate cut by the Federal Reserve later this week, with JPMorgan predicting the move and CME Futures data indicating a 67% probability. The Dow and equal-weight S&P 500 also hit record highs overnight, though gains were modest.
Notable stock movements include a 15.5% rise in Platinum Asset Management following a buyout bid from Regal Partners, a 4% increase in New Hope shares after a dividend announcement, and a 6% gain in Pacific Smiles due to a revised acquisition offer.
The SPI futures are pointing to a rise of 22 points.
