As you see in charts of $QQQ and $SPY we have broke all time hi with $DIA lagging. In previous moves we have seen leadership in $QQQ and $DIA before SPY broke all time hi. . Now we see that $DIA is lagging and $QQQ is leader which can mean change of market sentiment so caution is warranted.
Also we are little overbought and i think we will need more time for a rest.
Prior pivots on SPY are 240.70 , 235.50 and 139.75 ,136 for $QQQ where next bounce may happen.
