SPX Higher for Longer?
Dead-Cat Bounce?
Just the Christmas Rally?
Could be a number of things
With FED Liquidity increasing and quantitative easing in the US,
this may be sustained
OR
the 'soft landing' theme that has been thrown around for weeks can just be a good big dose of hopeium
In the realm of seasonality, SPX doesn't perform overly well during the first months of the year, so it is more than likely that once Dec. is over, higher prices wont be pushed day over day.
ATH's ?
So according to me, longer over a short-time horizon but neutral / down on a medium / longer tf.
