A "Powellful" rally with strong breadth

Keep an eye on a new high for the SPX A-D line and on a potential NYSE 90% up day

The S&P 500 (SPX) has rallied sharply after Chair Powell's Jackson Hole speech. The rally is broad, and the SPX's advance-decline line is probing to a new high with just a couple of hours until today's 4PM close. In addition, preliminary NYSE data suggest a 90% up day for NYSE breadth and volume. If these signals "stick the landing" into today's close, we would view it as a positive.
