With the afterhours jump (over 450 with volume), it is safer to assume we have completed blue "b". In fact, QQQ even touched 454 in afterhours. With this assumption, we could start to look forward to the push to Green A/Red B area (roughly QQQ 490)
454 is already within the target of what a wave 1 would be as the subwave to Green A. So, normally this could mean a wave 2 pullback should start from here. However, it is possible that market could extend itself further given the the news, and then start wave ii pullback.
These micro level movements impossible to figure out (the actual target below not accurate and only as illustrative purpose), but I think from here, market should favor "buy on dip" on the way to Green A
