Well, it's another day, and another set of new records that the S&P/ASX 200 Index (ASX: XJO) has notched. Yesterday, we covered the extraordinary moves that the ASX 200 made in hitting a new all-time record high of 9,230 points.
The index ended up closing at 9,227.8 points, up 0.9% and another record for a close.
Today, it seems investors aren't done with pushing the Australian share market into uncharted territory. The ASX 200 opened sharply higher again, and reached as high as 9,296.7 points soon after trading commenced. Things have cooled off a little since, but the index is still up a happy 0.5% at the time of writing at 9,274.3 points.
It's certainly been a month to remember for ASX investors. Since this time in July, the ASX 200 has now gained a whopping 5% (close to its annual average). If we measure from 24 July (just under two weeks ago), the gain sits at an even more impressive 5.7%.
Despite all that has happened in 2026, the Australian markets are, as of today's pricing, up 6.25% year to date in 2026 so far, and up 4.86% over the past 12 months.
What a time to be an Australian share market investor.

Why is the ASX 200 at new all-time highs today?
As my Fool colleague discussed yesterday, optimism abounds on the ASX. This is probably down to a few factors. We have the assumption, correct or not, that the hostilities in the Middle East, particularly in the Strait of Hormuz, are once again dialling back.
Aside from that, galloping US markets, which are also clocking record highs, are clearly spilling over into our market. Additionally, we had some recent economic data out for Australia that has many investors lowering their expectations for another interest rate rise later this year.
That all adds up to a fertile investing environment.
But let's look at some specific ASX shares.
As the S&P/ASX 200 is a fairly top-heavy index, its moves on any given day can normally be traced back to a few ASX blue chips. Namely, the big banks and big miners. It is no different today.
To start with, all four of the major ASX bank stocks are pulling their weight. Commonwealth Bank of Australia (ASX: CBA), for example, is currently up 0.65% at just over $179 a share. It's a similar story with its stablemates.
BHP Group Ltd (ASX: BHP), currently the ASX 200's largest stock with an index weighting of roughly 11.3%, has jumped 0.6% to $62.90 a share. That's after hitting $63.41 earlier this morning.
It's been another phenomenal day for Australian investors. Let's see how we end it, and tomorrow, the week.
