Tech Earnings Drive Intraday Moves

Of 14 S&P constituents reporting Monday, 8 beat consensus. The semiconductor sub-index rose 1.1%, leading all sectors. Energy fell 0.9% on the oil decline. Volume ran 12% above the 30-day average, signaling active institutional repositioning ahead of UNGA outcomes.

Fed Rate-Cut Odds Climb

CME fed-funds futures now price a 38% chance of a 25bp December cut, up from 22% last week. Last week's PCE core inflation print at 2.4% — below the 2.6% consensus — drove the shift. The 10-year yield fell 5bp to 4.41%; DXY slipped to 103.2.

Oil Faces Diplomatic Pressure Window

Brent at $81.20 hit a three-week low. Traders priced in a possibility that UNGA engagement could unlock Iran's 2 million barrel/day export capacity. Goldman Sachs holds a $90 target, arguing the diplomatic window is brief and structural supply deficits remain unresolved.
Tech earnings and geopolitical oil moves pulled markets in opposite directions Monday. Rate-cut odds rose; energy lagged. The week's direction depends on UNGA outcomes.
