SPX continues its upward impulse seeking liquidity. Major catalysts this week include FOMC Meeting minutes and GDP. OPEX this week as well could serve to trap in bulls/bears alike.
Personally, I look for topping/buyer exhaustion with these targets:
T1: 4298 - ABC Structure target of 1.78/0.618 fib retracement of larger move
T2: 4360 blowoff top, wave 5 extension by fib extension (Wave 1-3)
Afterwards, it's likely to see attempts to retake the highs before sellers step in for a cooldown. Likely by end of August/Early September.
