SPY has been in a bit of a tricky situation lately, stuck between the debt expansion of the fed which is bullish, and the yield curve and DXY going up which is bearish for SPY. Until the Fed implements Yield Curve Control (which I believe they will do in the near future) SPY could keep correcting and this volatility will remain. The market wants more debt expansion, so until we get it SPY will be indecisive.
