Sunday's watch list

Throughout US Treasury par yield curve The 10-year fell 15 bp to 5.09% in the week to 16 Oct; whether it holds decides if the rate-sensitive lifts in utilities and real estate extend.
Throughout Q3 earnings season continues Expected blended growth near 29.5% is the story behind a tape with structural breadth at −49.
Thu US weekly initial jobless claims A labour read ahead of the FOMC, with a market still weighing a hike after 3.7% CPI.
Fri CFTC Commitments of Traders Funds are net short 21.1% against a 17.2% mean; a cover would cut the +39 positioning support across every area.
Wed 28 Oct FOMC decision at the end of the 27-28 October meeting Warsh gave no signal; a hike would hit liquidity, already −32 tactical and −26 structural across the board.

Sunday's risks against the tape

  • The Fed hikes on 28 October CPI at 3.7% [1] and a non-committal chair [2] leave a hike live, which would land on a liquidity component already negative everywhere. S&P 500 +0.42% since Sunday · Financials −0.51% since Sunday · Real Estate −0.84% since Sunday · Utilities −1.69% since Sunday
  • Capex financing tightens Hyperscaler liabilities above $4 trillion [9] and a 5.09% 10-year make the build-out sensitive to credit; a pullback in issuance would hit the hardware layers already at 30-week lows. AI & Hyperscalers +1.80% since Sunday · Data Centers & Neoclouds +1.68% since Sunday · Semiconductors & Equipment +2.17% since Sunday · Memory & Storage +4.43% since Sunday · Networking & Optics +1.65% since Sunday
  • Long yields reverse higher The rate-sensitive gains in the week to 16 Oct came with a 15 bp fall in the 10-year [14]; a reversal would undo them first. Utilities −1.69% since Sunday · Real Estate −0.84% since Sunday · Financials −0.51% since Sunday
  • A short squeeze lifts hardware Funds are net short 21.1% against a 17.2% mean, so a cover would hit the most oversold layers hardest and against the Risk-Off read. S&P 500 +0.42% since Sunday · Semiconductors & Equipment +2.17% since Sunday · Networking & Optics +1.65% since Sunday · Memory & Storage +4.43% since Sunday
