Stock futures were narrowly mixed on Wednesday, Nov. 8, as investors awaited details on Senate Republicans' plans for tax reform. 

Dow Jones Industrial Average futures were down 0.02%, S&P 500 futures fell 0.06%, and Nasdaq futures were up 0.02%. 

The S&P 500 declined 0.05%, and the Nasdaq fell 0.27% on Tuesday, Nov. 7. Indexes had been higher earlier in the day, even hitting intraday records, after closing at all-time highs in the previous session. The Dow Jones Industrial Average ultimately broke another record on Tuesday, inching up 0.02% at the close. 

Senate Republicans expect to release their take on tax reform on Thursday, Nov. 9, a week after the House GOP released its Tax Cuts and Jobs Act. Senate Finance Committee Chairman Orrin Hatch is scheduled to reveal details of the Senate bill at that time.

Senate Majority Leader Mitch McConnell said his chamber aims to debate the bill next week, while the House could pass its version around the same time. President Donald Trump's White House has pushed for tax cuts to pass by the end of the year. If that happens, it will be the first piece of major legislation since he assumed office in January.

"With the failure of health care and basically every other legislative initiative, [Republicans'] ability to govern is still very much in question," Brad McMillan, chief investment officer for Commonwealth Financial Network, wrote in a note. "A failure on tax reform, which seems close to the default assumption among many, would just give an answer of 'no' to that question. Taking that into the 2018 mid-terms would certainly raise the chances of losing the House and possibly the Senate."

However, in what could cause a disappointment to investors, Senate Republicans could delay corporate tax cuts and alter other aspects of the tax reform bill supported by Trump. Legislators are reportedly exploring postponing the $845 billion corporate tax cut until 2019, according to The Washington post. At the same time, Republican senators were planning to eliminate the state and local tax deduction, going further than the House, which retained part of the popular tax break.

It was a resounding victory for Democrats on Tuesday evening in elections in New York, New Jersey and Virginia. Democrat Ralph Northam beat Trump-backed Republican Ed Gillespie in the race for Virginia governor, while voters in New Jersey elected Democrat Philip Murphy, a former executive at Goldman Sachs, as their next governor. 
Northam's election was being viewed as a political setback to Donald Trump, who on Tuesday wrote on Twitter that "Ralph Northam will allow crime to be rampant in Virginia." But Trump also distanced himself from Gillespie, saying that Gillespie "did not embrace me or what I stand for."
The Democratic mayors of New York and Boston, both vocal Trump critics, also easily won re-election. Also in Virginia, Danica Roem beat out incumbent Robert G. Marshall for a seat in the House of Delegates. Roem is one of the first openly transgender elected officials, while Marshall often championed anti-LGBTQ measures. 

Wednesday marks a year since President Trump won the electoral college, but not the popular vote, ending one of the most divisive presidential campaigns in U.S. history. Since then, the Dow has gained nearly 29% in its best post-election one-year gain since Franklin D. Roosevelt won his fourth term in 1945. Roosevelt's vice president,Harry S. Truman, assumed the presidency when Roosevelt died early in 1945.
Former President Barack Obama saw a 1.8% gain in the Dow during the first year of his presidency. At that point, the economy was still in the grips of the Great Recession. However, that gain surged to a nearly 19% increase in the first year since his second win.
"Although no one at the time would have believed it, the 12 months since Election Day have been among the least volatile ever for equity markets; not to mention the solid 21% gain the S&P 500 Index racked up along the way that has the bulls smiling," said Ryan Detrick, senior market strategist at LPL Financial. 

Crude oil prices were again lower on Wednesday as traders gave back some of the large gains seen at the beginning of the week. Prices had rallied with their best gains in nearly a year on Monday, Nov. 6, as political unrest in Saudi Arabia fueled hope that production cuts among some of the largest oil producers in the world could continue beyond early 2018.  

West Texas Intermediate crude was down 0.5% to $56.96 a barrel on Wednesday. 

Snap Inc.  ( SNAP - Get Report) turned higher in premarket trading and then tumbled again after it was reported that China's Tencent Holdings ( TCEHY) has built a 10% stake in the struggling social media company.
Snap badly missed Wall Street's fiscal third-quarter expectations. The company reported a loss of $443.2 million, or 14 cents a share, on revenue of $207.9 million. Analysts were looking for a loss of $393.8 million, or 15 cents a share, on revenue of $235.5 million.

Snap has suffered from a losing streak ever since going public in March, failing to exceed Wall Street's expectations in all three of its earnings reports as a public company.

Following the release of the results, Snap surprised investors when it announced that it plans to completely redesign the Snapchat app. CEO Evan Spiegel also warned that there's a "strong likelihood" the design overhaul will be disruptive to Snap's business in the short term. Spiegel didn't specify when the Snapchat redesign would be rolled out.

Humana Inc. (HUM - Get Report) topped earnings estimates over its third quarter and increased its forecasts for full-year adjusted profit. The health insurer earned an adjusted $3.39 a share over its third quarter, higher than a targeted $3.26. For fiscal 2017, Humana expects adjusted earnings of $11.60, higher than a previous forecast of $11.50. 

Take-Two Interactive Software Inc. (TTWO - Get Report) was sharply higher in premarket trading on solid guidance for holiday sales. The video-game publisher anticipates full-year revenue of $1.74 billion to $1.84 billion, up from a previous range of $1.65 billion to $1.75 billion. The release of its NBA 2K18 game and its Grand Theft Auto franchise should continue to drive sales through the holiday season.
