Here are five key things investors need to know to start the trading day:

After last week’s losses and with Nvidia’s can’t-miss earnings report on the horizon, investors are wondering what’s next for the artificial intelligence trade. Can the sector that has captivated Wall Street and Silicon Valley in recent years once again lead the market, or are investors in for more choppiness?

Here’s what to know:

Months after former Federal Reserve Governor Adriana Kugler’s mysterious resignation, an ethics report released Saturday shows she broke the central bank’s stock trading rules.

The U.S. Office of Government Ethics found Kugler purchased shares of individual stocks instead of mutual funds, and made trades during the “blackout periods” around Fed policy meetings — both of which are violations of Fed rules. Kugler resigned after being denied a waiver by Fed Chair Jerome Powell for a disclosure form that showed she had prohibited stakes, Fed officials familiar with the matter told CNBC.

Speaking of the central bank: The Financial Times reported that New York Fed President John Williams met with Wall Street dealers about a lending facility last week. Williams was looking for feedback on the Fed’s use of a standing repo facility, a permanent lending tool that can backstop markets, per the report.

The Federal Aviation Administration last night announced it is ending its mandated flight cuts at 40 major airports, effective this morning. More than 5 million travelers saw their flights canceled or delays during the government shutdown, when air traffic controller staffing concerns led the FAA to impose restrictions.

The government shutdown may now be over, but the years-long air traffic controller shortage is still a problem. As CNBC’s Leslie Josephs reports, the closure may end up making it even harder to staff up. Airline executives want lawmakers to ensure controllers and other airport employees would be paid if the government closes again.

After six straight years of declining domestic sales, Jeep wants to stop spinning its wheels.

As CNBC’s Michael Wayland reports, the SUV maker is aiming for a comeback after struggling with leadership changes, a dry product pipeline and consumers’ sticker shock. Jeep has seen some green shoots: The company recently saw its best quarterly sales growth in more than two years and has been rolling out new offerings such as the redesigned Grand Wagoneer.

Meanwhile, Ford ceremonially opened its 2.1-million-square-foot facility in Dearborn, Michigan, over the weekend. The new complex replaces Ford’s so-called “Glass House” headquarters and includes a test track, dual-level courtyard and even $6 rotisserie chickens.
