Here are the key election races Wall Street is watching as early indicators

Congressional races in Indiana, Kentucky, Florida and Virginia will be among the first Wall Street is watching to see whether the electorate’s response to President Donald Trump‘s programs is strong enough to launch either a “red wave” of support or a “blue wave” backlash.

The view of major firms such as Bank of America Merrill Lynch, Goldman Sachs and Morgan Stanley is for a mixed outcome, with Democrats gaining control of the House and Republicans holding or even adding to their majority in the Senate. The market reaction to that scenario could be muted, but not so if there’s an upset, with either party staging a surprise victory and gaining total control of Congress.

Stocks could rally if there’s a GOP surge — or red wave — and some strategists see a sharp decline if Democrats overcome the odds and take both the House and Senate.

Key early indicators of blue or red wave:

• Kentucky — polls start closing at 6 p.m. ET
• Indiana — polls start closing at 6 p.m. ET
• Virginia — polls close at 7 p.m. ET
• Florida — polls start closing at 7 p.m. ET

For that reason, investors are tuned in to the early races, which can’t tell the whole story but could give clues to the broader outcome of the midterm elections. One of those races is being fought in the 6th District of Kentucky, where Amy McGrath, a retired Marine lieutenant colonel, is challenging GOP Rep. Andy Barr.

“It’s going to be one of the first races [to close]. If she wins, it’s very positive for Democrats. If he wins, it’s not hugely negative, but it’s not good for the Democrats. Kentucky is so Republican. This is in Lexington, where the University of Kentucky is. … There’s a liberal area of Lexington, but there’s the farm area outside,” said Tom Block, Fundstrat Washington policy strategist.

Block said he will also be focused on Virginia, where Rep. Scott Taylor is defending his seat in the 2nd District against Elaine Luria, who, like Taylor, is a Navy veteran. In Virginia’s 5th District, Republican Denver Riggleman is running a close race against Democrat Leslie Cockburn for a seat vacated by Rep. Tom Garrett, who is retiring. A third Virginia House seat is up for grabs in the 7th District, where Rep. Dave Brat is running against former CIA operative Abigail Spanberger in a close race for a seat that has been in GOP hands for decades.

“Between Kentucky and the two or three Virginia races, if the Republicans are winning them all, it means they could hold the House,” said Block.
