Recent hotter-than-expected October CPI data, with headline inflation rising 0.4% versus 0.3% consensus, has shifted trader focus toward elevated December FOMC rate-hike odds, including a possible 50-basis-point move. This has pressured the S&P 500, which closed November 11 at 7,619.38 after trading between roughly 7,354 and 7,689 so far this month, remaining about 2.6% below its October 6 high near 7,819. Rising Treasury yields, persistent core inflation readings, and comments from Fed officials such as Governor Waller have reinforced expectations that monetary policy will stay restrictive longer than previously anticipated. The upcoming November PPI release and December FOMC meeting represent key near-term catalysts that could further influence equity valuations and market-implied levels for the remainder of the month.
