Mixed factory data accompany narrower losses as QQQ outpaces SPY

QQQ and SPY opened 0.94% and 0.66% below their previous closes, then pared losses. QQQ finished down 0.30%, ahead of SPY's 0.49% decline by 0.18 percentage points. A stronger S&P Global manufacturing reading and a softer ISM print framed the session's factory signals, while Taiwan tariff negotiations and Nvidia's Synopsys investment added semiconductor-policy context.
