There's news from FED & FOMC. The basic gist:
The Fed left the rate unchanged at 5.5%
Powell gave a strong signal that the Fed has likely already ended the rate hike cycle stating that he believes it is unlikely that the Fed will continue to raise rates and that the start of a rate cut is now on the table.
Powell left the option of further rate hikes if the U.S. economy grows above trend.
So here goes. In fact, the market has been left with the same data. The rate is 5.50%, inflation is in the neighborhood of 3.1%. NOTHING HAS CHANGED
People on empty words and rumors, when before the actual changes in key data is still a few months and everyone understands about it, reacts as abnormal. Apparently there was an internal psychological hunger on the background of long waiting for any hints or actions.
But I have already said many times - this is news. And that is the problem with this nuance as a trading instrument. You do not know beforehand how the market will behave even on predictable things.
