Big Bank Earnings Meet CPI With Stocks Near Records

JPMorgan, Goldman Sachs, Citigroup and Wells Fargo were set to report third-quarter 2026 results in the week starting October 9, with bank earnings and CPI headlining the market calendar while the S&P 500 hovered near records. CPI is the Consumer Price Index, the monthly read on household inflation that helps set borrowing costs.

The lineup put the money-center and wholesale franchises first. Money-center means large nationwide banks, wholesale means Wall Street trading and deal work. JPMorgan and Goldman Sachs were among the banks due that week, when earnings and inflation data were expected to dominate price action. A separate preview listed JPMorgan, Goldman Sachs, Citigroup and Wells Fargo as the Q3 reporters in focus. Reuters

Consensus entered the week with strict targets. Analysts polled by FactSet expected the five biggest Wall Street banks to grow per-share earnings by an average of 20% from a year ago. Per-share earnings is profit divided by shares outstanding. Analysts on average expected S&P 500 earnings to jump over 30% ahead of the third-quarter earnings season starting with reports from large U.S. banks. Reuters

Trading was the swing factor. The Wall Street Journal published an article titled "Wall Street's Trading Desks Come Down From a Record High" on September 30, framing the quarter around normalization after an exceptional run. Normalization means a return toward average levels. Investment-banking revenue reached $61.4 billion in the first half of 2026, up 24% from a year earlier, according to Dealogic data.

The calendar pattern was familiar. In its July 13, 2026 stock-market live coverage, the Journal noted investors were gearing up for a busy week of bank earnings and key inflation data, the same joint earnings-plus-CPI test that defined the October week. On the strategy side, the Journal published an article titled "October: A Time for Investors to Reap…and Sow" on September 29.

The broader context here is base effects and sequencing. Trading was cooling while fees held up. That split leaves the Q3 read in two lines: principal transactions, or gains from the bank's own trading, and the underwriting plus advisory mix inside investment-banking revenue. A 20% bank consensus against a 30%-plus S&P 500 target puts banks below the index hurdle. If trading falls back from a record while first-half fees annualize near the $61.4 billion Dealogic tally, the test is whether fees offset that drop. The CPI print in the same window adds joint risk. Stocks near records tend to price in clean wins, not weak mixes.

In my view, readers should watch dispersion rather than the group average. The 20% figure is an average across five franchises with different weights on trading, advisory, underwriting and lending. A uniform beat driven by reserve and tax items reads differently from one driven by client activity. Early bank prints set the tone for cyclicals and credit, but they do not settle the earnings season. They narrow the range for what later reporters must deliver to sustain valuations already built on high expectations.
