An anomaly has occurred within the Blue chips on the ASX over this last fortnight.
South 32 (‘S32’, BHP Spin-off) and RIO went in opposite directions. Most of the time if RIO is up, so too is BHP (previously including S32). However the recent BHP spin-off, S32, is in the Top 5, while RIO is in the Bottom 5.
This type of anomaly often precedes a good (or bad) market update / announcement for the company ion S32’s (RIO’s) position, depending on how the rest of the sector is performing.
