The ASX 200 surprised many on the open yesterday, “gaping up” around 100 points above where it was “supposed” to open, leaving many scratching their heads, but as Shawn rightly pointed out, it’s not the first and won’t be the last example of market shenanigans on the expiry of the SPI Futures – particularly quarter end expiry. By the close, the local index still managed to finish +0.4% higher, aided by a more than +1% pop by US Futures in their late trade and an average +2% gain by the “Big Four” ASX banks.
