"Calm is emerging in the search for balance on Wall Street."

American stock futures remained largely unchanged on Tuesday night as Wall Street assessed a shift towards more defensive sectors among the major technology companies. Investors are preparing for a crucial congressional vote that will end the longest government shutdown in U.S. history.

Dow Jones Industrial Average futures stayed above the key level, while S&P 500 futures gained 0.1%. Nasdaq 100 futures also rose by about 0.1%.

Observers in Washington are focused on the Senate passing the spending bill aimed at reopening the government on Monday night. The bill is now set to go to the House of Representatives, where a vote is expected on Wednesday afternoon.

Following Monday's gains in the stock markets, Wall Street had a mixed session on Tuesday due to the largely anticipated effects of the government shutdown deal. Dow Jones closed at a record high with an increase of over 550 points, but the technology-heavy Nasdaq Composite experienced a drop as investors took profits in high-yield artificial intelligence stocks. S&P 500, meanwhile, marked its third consecutive positive day with a small gain.

In light of micro data, investors examined the ADP employment report, which indicated weaker-than-expected private sector job growth in October. This raised new concerns about a cooling labor market. The data became more significant given that the ongoing government shutdown has delayed some crucial federal economic announcements.

On Wednesday, several Federal Reserve officials are expected to speak. Among them are Stephen Miran, the latest appointee from President Trump, and Christopher Waller, who is nominated to be the next chair of the central bank. Investors are looking for clues about next month's Federal Reserve interest rate decision; currently, most expectations focus on a quarter-point reduction.

Earnings season is continuing at a slower pace as most companies have already reported. Major names to watch for the rest of the week include Cisco, Disney, and Applied Materials.
