Earnings season on Wall Street is off to a mixed start.

JPMorgan Chase, Goldman Sachs, Wells Fargo and Citigroup all reported third-quarter results Tuesday morning.

"The U.S. economy continued to be fueled by strong business investment and ongoing consumer spending," Chief Executive Jamie Dimon said.

JPMorgan reported a slowdown in investment-banking. Goldman Sachs posted its second-best quarter ever for revenue. However, both banks reported a sequential slowdown in fixed income trading.

Meanwhile, Wells Fargo said profit rose 6% from a year ago, but its revenue fell short of estimates.

Citigroup said total profit jumped 40% while revenue climbed to $23.85 billion, its best third-quarter in a decade. The quarterly growth is extra high because a year ago, the bank took a goodwill charge on the plans to shed its Mexican bank Banamex.

Here's the breakdown of results:

JPMorgan Chase:

The nation's largest bank reported earnings that fell short of Wall Street's expectations after the company saw a slowdown in markets and investment-banking activity.

JPMorgan reported a profit of $15.31 billion, or $5.57 a share, in the third quarter. Analysts polled by FactSet were expecting per-share earnings of $5.93.

JPMorgan's revenue rose 8% from a year earlier to $50.17 billion, falling short of the $51.23 billion expected by Wall Street analysts.

The results were hit by a $658 million loss on investment securities on the bank's books.

Client activity among the bank's markets and investment-banking clients moderated during the quarter from the strong second quarter, Dimon said. However, revenue from trading stocks and bonds fell in the third quarter from the prior period. Executives had cautioned during the quarter that the third quarter wouldn't be as sweet as the second for trading.

Dimon noted that large fiscal deficits, sticky inflation, elevated asset prices, rising interest rates and geopolitical conditions continue to shift under the surface.

Goldman Sachs:

The bank reported its second-best quarter ever for revenues, driven by a boom in its equities business and higher investment-banking fees.

The bank posted a profit of $5.29 billion in the third quarter, or $17.01 per share, a 29% increase from a year earlier.

Revenue rose 23% from a year earlier to $18.68 billion.

Analysts polled by FactSet expected a profit of $12.86 a share on $16.83 billion of revenue.

Equities revenue rose 72% to $6.44 billion. The bank cited "significantly higher" net revenues in equities financing and intermediation. Meanwhile, investment banking fees increased 21% to $3.22 billion

Wells Fargo:

Wells Fargo says its profit rose 6% in the third quarter from a year ago but revenue fell short of estimates.

The bank said it earned $5.95 billion for the period, or $1.87 per share. Wall Street analysts expected a profit of $1.85 per share, according to FactSet.

Revenue for the quarter came in at $21.87 billion, below the $22.31 billion analysts expected.

"While economic uncertainty exists and consumer sentiment remains mixed, our data shows that our consumer and business customers are doing well," CEO Charlie Scharf said. "Consumers are spending more, loan delinquencies are low, and deposit and investment balances have grown. Businesses continue to have strong balance sheets and losses remain low. While higher interest rates, higher oil prices and persistent inflation create risks to the economy, strong positive forces such as the investment in AI infrastructure, high employment levels and consistent wage growth continue to outweigh the risks," he said.

Citigroup:

Citigroup posted net income of $5.2 billion, or $2.85 a share, up from $3.8 billion, or $1.86 a share, a year earlier. Revenue reached $23.8 billion, driven by growth in services, wealth, markets and banking.

Net interest income rose 14% while services revenue was up 15% and equities climbed 14%. Banking grew 6% and wealth had broad-based growth across its three businesses.

"We expect to exceed this year's return target, even as we pull forward investments toward our 11-13% near-term goal - the next waypoints on our path to sustainable returns of 14-15%," Chair and Chiex Executive Jane Fraser said.
