The market has been choppy in FY27 so far.
Between 30 June and 6 August, ASX 200 shares rose 5.6%.
This was partly due to strong US tech earnings inspiring renewed confidence in the AI boom.
The benchmark then tumbled 7.1% as persistently high inflation led to an interest rate hike on 30 September.
The ASX 200 troughed on 1 October and has since rebounded 5.9% on hopes the US will end the war in Iran.
Following another rate increase on 4 November, investors are also now hopeful the hiking cycle is over.
This week, brokers reaffirmed their buy calls on several ASX 200 shares amid this renewed optimism.
Let's check them out.
