U.S. equities closed mostly lower Tuesday, as semis, memory, and software led declines amid a broader risk-off tone driven by higher yields and rising oil. WTI crude jumped 4.2% back above $100/barrel on lingering US-Iran tensions, Treasuries weakened with the 30Y yield back above 5%, and a hotter-than-expected core April CPI print reinforced market pricing leaning toward modestly more Fed tightening through year-end.
