The 08/22/24 blog “Buy the Rumor – Sell the News – 08/22/24” noted.
“On 08/23/24 FOMC – chairman Jerome Powell speaks at the annual Jackson Hole symposium. Perhaps the Speech could trigger the Minute wave [v] final rally of the post 08/05/24 bull move”.
There’s was a rally on Powell’s comments. Could the presumed Minute wave [v] be complete? If so a significant top may have been made.
The 5 – minute S&P 500 (SPX) chart courtesy of Trading View illustrates an interesting scenario that could develop.

About 90% of the time the fifth wave of a motive pattern exceeds the termination point of the third wave. In this case the third wave was the Minute wave [iii] peak at 5,643.22 made on 08/22/24. The SPX high on 08/23/24 was 5,641.82. In Elliott wave theory when the fifth wave of a motive pattern fails to exceed the termination point of the third wave its called a truncated fifth wave.
This may have happened, however note the subsequent decline appears to be a three-wave corrective move. The next rally exceeded the presumed Sub Minuette wave “b” peak and retraced more than 90% of the sessions decline. Going into the weekend it appears the bulls still have considerable strength.
An Elliott wave – Ending Diagonal Triangle could be forming. This pattern appears in the fifth wave position of motive patterns and terminate larger movements.
R.N. Elliott said Ending Diagonal Triangles appear after a market has moved too far too fast. This perfectly describes what’s happen in the U.S. stock market since the 08/05/24 mini crash bottom.
A significant top for U.S. stocks could be made on 08/26/24.
Side note, the SPX rally from late September 1986 to late August 1987 ended on 08/25/87.
