Powell Speech Friday - Market Up/Down?

To sit on the Fed chair is definitely not going to be fun, albeit the big salary the chair will be compensated. We have come to accept the scenarios that central bankers are likely to be ambiguous when it comes to monetary policy, in that it allows flexibility to argue and adapt to future happenings. Powell's predecessor like Alan Greenspan, is well known for his ambiguity in his speeches.
In this high inflation scenes, in the past few days, we have heard the likes of other Fed presidents's speeches with a high of 3.75% to 4% by year end. So definitely further rate hikes are likely between now and year end, and if everything goes expected, then a hike of 75bps is very likely to come in September?
However, Fed is banking on economic indicators like job markets, Core PCE (which has jumped to a high level of 6.8%) etc, which has remained strong in figures, giving the Fed more compelling reasons to curb inflation with hiking rates. Then how will the markets react to this all the way approach..
Markets is more likely to be down, especially the Tech sectors, which may drag down the overall market sentiment.
