There were several encouraging signs on Thursday: SPY essentially held Q2P again (close enough), and DIA & NYA both did as well; IWM held onto its OctP too. So that several quarterly and monthly pivot holds for USA main indexes.
However, SPY, DIA and NYA all under OctPs which are still resistance and SPX YR1 looms just ahead. If you are long you don't want to see two weak advances that are unable to take out resistance.
SPY looks better but SPX looks like that YR1 is keeping the lid on the rally and next move more likely down. We'll see what happens.
