Now, let's take a look at the top and bottom movers.
US President Donald Trump announced a new round of drug-pricing agreements with international pharmaceutical companies and some smaller biotechs, including CSL, on Monday, part of a push to make healthcare more affordable for Americans.
These companies have offered drugs to state Medicaid programs at most-favoured-nation prices, President Trump said, describing this as "a tremendous discount, which should bring down the cost of your medical care by tremendous amounts".
It is not clear how many drugs the deals cover or at what discounts, leaving the savings for the government or patients unknown.
The White House did not release details of the agreements and companies in separate press releases described some terms as private.
The administration and some of the companies said there would also be future savings from innovative drugs, and agreements to manufacture more products in the US.
The shares of CSL were up 1.2%, trading at $173.56 per share as of 11:45am AEST.
Oil prices gained on Tuesday as the resumption of fighting between the US and Iran in the Middle East renewed fears of supply disruptions from the world's key crude-producing region.
Brent crude futures were up 0.6%, to $US91.05 a barrel at 10:44 AEST, while US West Texas Intermediate crude was up 1%, to $US86.59.
In the previous session, Brent closed up 2.7%, at one point reaching its highest since August 25, and WTI settled up 2.8%, touching its highest since August 21.
