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

Investors yesterday were pleased with the Senate’s approval of an agreement that could end the government shutdown. The three major indexes all surged in Monday’s session, regaining ground after posting sizable losses last week.

Here’s what to know:

The tech-heavy Nasdaq Composite saw its biggest one-day rally since May, signaling traders’ shift back into the artificial intelligence trade. Microsoft snapped its longest losing streak since 2011.Bitcoin climbed back above the $105,000 mark, another sign of the deal boosting animal spirits in the market.The Senate officially passed the bill in another vote last night, sending it to the House of Representatives.Earlier in the day, House Speaker Mike Johnson did not commit to holding a December vote on extending enhanced Affordable Care Act subsidies — one of the deal’s key guarantees for Democrats. Here’s what Democrats are, and aren’t, getting in the deal.Johnson said members of his chamber should return to Washington, D.C., to vote on the deal as soon as possible. Members of Congress were told that votes in the House could begin by 4 p.m. ET tomorrow.When asked if he supports the agreement, President Donald Trump on Monday said “I would say so.”Follow live markets updates here.

Japanese firm SoftBank said Tuesday that it sold all of its stake in Nvidia for $5.83 billion. Nvidia shares slipped nearly 2% in premarket trading this morning.

The sale comes as SoftBank focuses its attention on OpenAI, the buzzy startup behind ChatGPT. But SoftBank is still involved with Nvidia through other artificial intelligence ventures that use the chipmaker’s technology, such as the Stargate project.

SoftBank also dumped some of its T-Mobile position for $9.17 billion.

Paramount Skydance announced more plans to cut costs, lay off employees and raise prices yesterday. Shares jumped as much as 5% in overnight trading.

The CBS parent said it’s aiming to trim an additional $1 billion from its business. As CNBC’s Lillian Rizzo notes, that’s on top of the $2 billion in savings the company outlined when its merger completed in August. Paramount also announced its latest round of layoffs, tied to its divestiture of parts of its South American business, impacting about 1,600 employees.

The entertainment company said it would hike prices for its Paramount+ streaming service in the first quarter of 2026.

Air travel remains under pressure as the government shutdown strains airport infrastructure. Just over 6% of U.S. flights were cancelled yesterday, according to aviation data firm Cirium.

Air traffic controllers, who are required to work during the shutdown, missed their second full paycheck yesterday. Trump said he would recommend a $10,000 bonus for controllers who don’t take off time during the shutdown, while threatening to dock pay for those who don’t go to work.

Flexjet global CEO Andrew Collins told CNBC’s Leslie Josephs that demand for flights on private planes has jumped sharply in recent days. But the Federal Aviation Administration on Monday limited private flights at 12 major U.S. airports amid the staffing challenges.

Berkshire Hathaway CEO Warren Buffett plans to “step up” the pace of giving away his $149 billion fortune to his children’s foundations, according to a letter released yesterday.

But Buffett said he would hold onto a “significant amount” of Class A shares so investors can build confidence in his successor, Greg Abel. Buffett said it “shouldn’t take long” for shareholders to warm up to Abel, who will take over as chief executive next year.

Buffett said his letter will become a Thanksgiving tradition and that Abel will take over writing Berkshire’s annual shareholder letters. In typical fashion for the investing titan, the Oracle of Omaha used his note on Monday to dole out some life advice, too.
