Today’s drivers for ON Semiconductor

Today, September 16, 2026, ON Semiconductor faces a backdrop of elevated energy prices and firmly high Treasury yields that continue to influence risk appetite in U.S. equities, particularly rate-sensitive technology and semiconductor stocks, as highlighted in the September 15, 2026 market coverage by Barchart.com. In addition, investor focus today remains on the upcoming Federal Reserve rate decision, which has been cited as a key overhang for growth and semiconductor valuations in recent pre-meeting coverage by CNBC.
