2026 Q2 Earnings Preview: S&P 500 Earnings Growth of 21.2%, Bank Stocks’ Splits Worsen

On July 13, 2026, the six largest banks in the United States will officially kick off the Q2 earnings season. Prior to this, the earnings expectations for the S&P 500 have been revised upward for several consecutive months—rising from +18% in early April to the current +21.2%. Overall, this is undoubtedly a strong quarter: out of the 16 Zacks industry classifications, 11 are expected to see positive earnings growth.

However, when we shift our focus from macro totals to individual stocks, a completely different picture emerges. As of June 12, 2026, Citigroup (C) has gained 20.86% year-to-date, while Wells Fargo (WFC) has fallen 9.20%, and JPMorgan (JPM) has nearly stagnated (+0.47%), with Bank of America (BAC) up slightly by 2.87%. In the same sector and macro environment, the return gap exceeds 30 percentage points.

This divergence is not random fluctuation but a concentrated reflection of differences in business structure, interest rate sensitivity, cost efficiency, and strategic execution among these banks. For investors, the Q2 earnings season is not only a key moment to validate these divergences but also potentially the starting point for a new round of re-pricing.

S&P 500 Q2 Earnings Expectations: Strong Total, Structural Divergence

First, look at the total. As of mid-June 2026, the overall profit forecast for the S&P 500 in Q2 is a year-over-year increase of 21.2%, with revenue growth of 10.7%. This expectation has been significantly revised upward from 18% in early April, reflecting a continued improvement in corporate earnings visibility within the quarter.

But beneath the total, key structural features are hidden.

The technology sector remains the biggest growth engine. Q2 earnings growth expectations for the tech sector are as high as 42%. If we exclude the contribution of the tech sector, the earnings growth for the rest of the S&P 500 would plummet from 21.2% to 11.3%. This means the overall index’s strong growth heavily depends on the performance of a few tech giants.

Energy and basic materials sectors are emerging strongly. The improvement in energy earnings expectations is directly related to geopolitical factors—rising energy prices due to tensions with Iran, boosting energy companies’ profit outlook. The chemical industry within basic materials also benefits from this. These non-tech sectors’ upward revisions partly offset downward pressures in other industries.

Financial sector: contributor or drag? The financial sector already showed strong profit contributions in Q1—out of the $9 earnings per share (EPS) for the S&P 500 that quarter, financial stocks contributed $3. The market expects about 116% earnings growth for the financial sector in Q2, accounting for roughly 25% of the overall S&P 500 profit growth. Whether the financial sector can sustain this momentum will largely determine if Q2’s overall profits can meet or even surpass current expectations.

The Six Major Banks’ YTD Performance Overview: A Divergence Map

As of June 12, 2026, the performance of the six major banks this year is as follows:

| Bank | YTD Performance | | --- | --- | | Citigroup (C) | +20.86% ~ +21.03% | | Bank of America (BAC) | +2.87% ~ +2.96% | | JPMorgan (JPM) | +0.47% ~ +0.50% | | Goldman Sachs (GS) | +22.08% | | Morgan Stanley (MS) | +21.88% | | Wells Fargo (WFC) | -9.20% |

For comparison, the S&P 500 has risen about 9.08% in the same period. Citi outperformed the market by over 11 percentage points, while WFC lagged behind by more than 18 points.

Why did Citi lead? Citi’s strong performance can be understood from two dimensions. First, it demonstrated robust momentum in Q1—on April 14, 2026, Citi announced Q1 EPS of $3.06 and revenue of $2.46 billion, both surpassing market expectations. Second, market recognition of its transformation strategy has continued to grow. Citi’s cumulative gain over the past year has reached about 66%, far exceeding the S&P 500 and its peers. This “excess return” reflects market confidence in its restructuring and capital return plans.

Why is WFC at the bottom? WFC’s weakness is also traceable. After its Q1 earnings report, WFC’s stock plunged 6.6% in a single day, mainly due to revenue falling short of expectations and net interest margin remaining under pressure. Deeper issues relate to cost efficiency—WFC’s Q1 efficiency ratio was 67%, higher than Citi’s 62% and BAC’s 61%, meaning WFC needs to spend more to generate each dollar of revenue. In a “higher for longer” interest rate environment, the uncertainty around net interest income further amplifies market concerns.

Why is JPM “stagnant”? JPM’s performance is the most intriguing. As the largest bank in the U.S., JPM’s fundamentals are solid, with Q1 EPS expected around $4.99 and net profit growth forecast at 29.3%. Yet, its stock price has remained nearly flat, reflecting a re-pricing of valuation and growth expectations—after significant gains in recent years, JPM may be entering a phase of “fully priced expectations.”

The Threefold Logic Behind the Divergence

This divergence is not accidental but the result of the superposition of three structural forces.

First, asymmetric responses of business structures to the interest rate cycle. In a “higher for longer” rate environment, banks with a higher proportion of net interest income face greater margin pressure. WFC’s traditional retail banking business has a higher sensitivity to interest rate changes; in contrast, Citi’s diversified revenue streams from market and wealth management provide more resilience.

Second, the gap in cost efficiency becomes more pronounced as profit growth slows. When industry revenue growth stabilizes, operational efficiency differences directly translate into profit margin gaps. WFC’s efficiency ratio of 67% versus Citi’s 62%—a 5 percentage point difference—can mean billions of dollars in profit at the annualized revenue scale.

Third, market expectation gaps as sources of excess returns. Citi’s continued rise partly stems from market expectations of its transformation gradually materializing—from “restructuring story” to “performance validation.” Each positive surprise triggers valuation re-rating. Conversely, WFC’s ongoing decline reflects market doubts about whether its asset cap removal will truly lead to efficiency gains.

Q2 Earnings Season: A Key Window to Validate Divergences

The 2026 Q2 earnings season will officially kick off on July 13, with the big banks leading the way. This timing is critical for three reasons:

First, expectations have already been significantly revised upward. Q2 earnings estimates have risen from +18% in early April to +21.2%. With expectations already high, “beating” becomes more challenging, and any underperformance could trigger larger-than-usual negative reactions.

Second, macro uncertainties remain. Sticky inflation, delayed rate cuts, risks in commercial real estate—all continue to suppress risk appetite. Q2 earnings are not only about performance validation but also about management’s outlook for the second half—this guidance may have a greater impact on stock prices than the earnings themselves.

Third, divergence may intensify further. If Citi delivers another strong quarter, its leadership position could be reinforced; if WFC’s net interest income remains under pressure, its lag could widen. Conversely, any “unexpected positive” or “unexpected negative” surprises from any bank could trigger a re-pricing within the sector.

Conclusion

The 2026 Q2 earnings season will officially commence on July 13. The overall profit forecast for the S&P 500 is a 21.2% YoY increase—seemingly optimistic—but the high divergence in big bank performance reminds us that macro totals conceal profound micro-level cracks.

The +20.86% of Citi versus the -9.20% of WFC is not just a numerical gap but the result of the combined influence of business structure, cost efficiency, and market expectations. The Q2 earnings season will be a key test for these dynamics—outperformance could widen the gap further, while underperformance might trigger sharper re-pricing.

For investors, this presents both challenges and opportunities. Whether betting on continued outperformance of leaders or on turnaround of laggards, the Q2 earnings season offers abundant trading opportunities. Meanwhile, Gate’s stock trading service, with its low barriers and high efficiency, opens a gateway for crypto holders to participate in this market environment.
