Federal Reserve chair Jerome Powell is scheduled to speak at the central bank's annual Jackson Hole Symposium on Friday, an event that could be a major test of the stock market's post-"Liberation Day" rally.

Federal Reserve Chair Jerome Powell's speech at the Jackson Hole conference on Friday comes amid the labor market showing signs of weakness and inflation ticking higher due to tariffs.

Among the Nasdaq 100 stocks, Analog Devices ADI and Palo Alto Networks PANW rallied 3.7% and 1.6%, respectively, making them some of the best performers at the market open. On the downside, Intel INTC and Micron Technology MU tumbled 4.1% and 3.6%, respectively.

Stocks might get their September interest-rate cut, but the Federal Reserve could still disappoint the market, as soon as this month.
