Markets surged in August and even though a one-way market will often most wash cycles away our LT wave did fairly well.
Expected strength in the first week of August was followed by a sideways in the subsequent weak period. The market then burst to new all time highs during the next strong period. The final days were flat again.
September is supposed to start with weakness until around the 12th. Not all weak periods are gentle sideways and investors may become a bit overconfident after such an “easy summer”. So, I would be careful. The 3rd week of September is expected to be stronger and the final week is weak again.
