JPMorgan Chase’s Closest Rhyme Ends Before the Fed’s 2004 Pivot

The Rhyme

JPMorgan Chase today looks surprisingly like JPMorgan Chase in the spring of 2004. From May 19 through September 25, 2026, the stock’s 90-trading-day path rose 16.5%. Its closest historical match is the stretch from December 10, 2003 through April 20, 2004. The two paths climb, hesitate near their highs, and finish together at TODAY = 100 with a Rhyme Score of 95.6.

The old path was forming around a company-changing deal. On January 14, 2004, J.P. Morgan Chase announced its agreement to merge with Bank One. Management described the combination as a way to balance wholesale and retail banking, add geographic reach, and create a firm with more than $1 trillion of assets. The merger had been announced, but it had not closed when the analog ended.

Rates were also at an inflection point. On March 16, the Federal Reserve held the federal-funds target at 1% and said it could be “patient” in removing accommodation. That language captured the tension at the endpoint: growth was solid, inflation was still described as low, and the market was beginning to look past an unusually easy policy setting.

What Happened Next

The historical continuation did not become a dramatic collapse or a straight-line rally. JPMorgan Chase fell 7.3% over the next 1 month and was still down 3.6% at 3 months. By 6 months, it had returned to almost exactly where the match ended: +0.3%. The maximum drawdown during that six-month window was 8.9%.

Two weeks after the analog endpoint, the Fed changed its message. On May 4 it kept the target rate at 1%, but replaced “patient” with guidance that accommodation could be removed at a pace likely to be measured. The first quarter-point increase followed on June 30. The Bank One merger closed the next day, July 1, at a reported purchase price of $58.5 billion.

The transition was not frictionless. JPMorgan Chase later reported a $548 million second-quarter loss after a $2.3 billion after-tax addition to litigation reserves and $60 million of after-tax merger costs. Its filing also said expected higher rates had reduced mortgage originations and margins. Those developments overlapped with the continuation, but the chart does not assign each move to a single cause.

Why This Rhyme Is Interesting

The match is interesting because the endpoint sits between anticipation and execution. In 2004, the merger was agreed but unfinished, and the Fed had not yet begun raising rates. The stock’s path had already absorbed a large amount of optimism before both transitions became concrete.

The six-month endpoint is also a useful corrective to dramatic analog storytelling. The historical path first declined, then recovered to roughly flat. A 95.6 Rhyme Score describes the shape of the observed 90-day windows; it does not specify what must come after them.

Where the Rhyme Breaks

The current company is operating at a different scale and under a different earnings mix. JPMorgan Chase reported second-quarter 2026 net income of $21.2 billion, or $16.9 billion excluding significant items. The quarter included a $4.6 billion net gain related to Visa shares and $1.0 billion of gains on certain equity investments; investment-banking fees rose 30% and Markets revenue rose 35% from a year earlier.

The current rate setup is nearly the reverse of early 2004. On September 16, 2026, the Fed raised its target range to 3.75%–4.00% and said inflation remained elevated. In April 2004, the target was 1%, the Fed was preparing to remove accommodation, and the heritage JPMorgan Chase was waiting to complete a transformative merger.

There is a narrow similarity: in both periods, a strong price path coincided with meaningful corporate developments and shifting expectations for monetary policy. The balance sheet, business mix, starting rate, earnings composition, and specific risks are different.
