How the market response compared with historical patterns
The S&P 500 returned -0.30%, against a model estimate of -0.21%. The actual return was 0.09 percentage points below the estimate based on historical news relationships.
The input preserved the mixed earnings picture: Alphabet’s shortfall, Caterpillar’s stronger overall results but weaker construction sales, and Microsoft’s earnings beat alongside infrastructure-delivery concerns. It also distinguished the previous day’s Fed decision from the new PCE release.
Absolute gaps at least this large occurred on 90.7% of the preceding 204 evaluation days.

| Historical 95% error band | -1.92% to +1.52% |
CNBC recap and supporting context
The Nasdaq fell more than the S&P 500 and Dow as investors digested large-company earnings. Alphabet dropped about 12% after missing adjusted earnings and revenue expectations, reporting negative free cash flow and maintaining substantial capital-spending plans.
Caterpillar’s results were more nuanced: overall revenue and earnings exceeded expectations, but construction-industry sales were slightly below estimates. Microsoft also beat earnings and revenue forecasts, helped by Azure growth. Separately, its capital-spending commitment was interpreted as pointing to delays at infrastructure partners, weighing on neocloud suppliers.
The September PCE report showed accelerating inflation, with the monthly reading matching expectations and the annual rate slightly below estimates. The previous day’s Fed hold remained part of the backdrop. The timing alone does not establish either release as the direct cause of the day’s decline.

Text used by the model
The original Claude summaries and documented source-based edits were retained unchanged. Category tags, timing tags and the separate numeric-surprise field were not fed into the embedding model.
Alphabet missed expectations on adjusted earnings per share and revenue in the third quarter, posted negative free cash flow of $9.07 billion and kept its full-year capex forecast at $195 billion to $205 billion.
Caterpillar reported better-than-expected third-quarter revenue and earnings, but sales in its construction industries business came in slightly below estimates.
Growth in Microsoft's Azure cloud infrastructure business helped earnings and revenue beat analyst estimates for its fiscal first quarter ended September, per LSEG.
Microsoft's lower-than-expected capital spending commitment pointed to infrastructure partners taking longer to deliver data center capacity, affecting neocloud suppliers such as CoreWeave and Nebius.
On Wednesday the Fed held its benchmark rate at 3.75% to 4%, saying inflation remains elevated and that it awaits the accumulation of more information before further steps.
The September PCE price index showed price increases accelerated, with the monthly figure in line with expectations.
The annual September PCE inflation rate came in just below Wall Street estimates.
Calculation
Intercept b = -0.0006704786
Weighted embedding sum w·x = -0.0014529380
Estimated log return b+w·x = -0.0021234166
100 × (exp(b+w·x) − 1) = -0.212116%
The model was trained on 750 sessions from 2023–2025, with alpha fixed at 1 and unchanged local BAAI/bge-small-en-v1.5 weights. Error bands use absolute log-return errors from 204 evaluation days before October 26; all six sessions in this briefing window are excluded. These are historical error reference bands, not fair-value ranges or guaranteed coverage intervals. The gap does not identify an individual event’s causal contribution or establish market overreaction or underreaction. Method and source notes
