The ASX 200 put in a stellar performance on the penultimate day of September, advancing by +0.9% and reducing the month’s decline to 1.2% with just today remaining. Gains weren’t overly broad-based, with less than 60% of the main board closing higher, but when the “Big Four Banks” advance on average more than 1.8% the index is almost guaranteed to rally, and when it’s supported by the influential healthcare names, and a rampant gold sector, gains become magnified ultimately delivering the best day since September the 4th.
