The corporate earnings season kicks off in earnest this week, led by the six major U.S. banks. Goldman Sachs, Wells Fargo, JPMorgan Chase, Citigroup, Morgan Stanley and Bank of America are all scheduled to post fourth-quarter results. UnitedHealth is also among the roughly 20 S & P 500 names on deck to report. Expectations for the reporting period are high, with analysts estimating nearly 12% year-on-year earnings growth for the fourth quarter, according to FactSet data. If that’s the case, it would be the strongest yearly profit expansion since the fourth quarter of 2021. Take a look at CNBC Pro’s breakdown of what’s expected from this week’s key reports.

A conference call with analysts is slated for 8:30 a.m. Last quarter: JPM shares popped after the banking giant posted better-than-expected results . This quarter: Analysts polled by LSEG expect a 35% earnings jump from the year-earlier period.

This quarter: The bank is expected to report year-on-year earnings growth of nearly 50%, LSEG data show.

But HSBC thinks sentiment around the stock may be too downbeat. “With unknowns around policy decisions from the incoming Trump administration which could potentially shake up the health insurance sector, we try to outline five key debates that would matter for the investment case. Given the bearish sentiment and softer comps as we move through the year, there are opportunities for UNH to get back to an upgrade mode in the coming quarters,” analyst Sidharth Sahoo noted in an upgrade to buy from hold on Friday.
