Note that wave [b] is looking for a perhaps dramatic 50-60 point SPX pullback.
Obviously the GDOW may point to an [a][b][c] pattern for Minor 2. The SPX would likely follow suit in the same manner. The Minor 2 on the SPX has already been very deep up. 2000 SPX is again in the cards, but I don't really think the market gives a shit whether or not it tops the previous 2019 intraday high. That's just my gut reaction at the moment.
And a 50-60 point SPX pullback would be "normal" for a wave [b] based on 38% Fib marker of the rise since the 1820 low..
