Following a third consecutive day of strong market activity, U.S. futures fell slightly Thursday night, an unwelcome sign during a continuing period of uneasiness for traders following the U.K.'s decision to exit the European Union.

All three futures markets were in the red Thursday evening, with the Dow Jones Industrial Average  down 0.08%, and the S&P 500  and Nasdaq  drooping 0.12% as of 9:40 p.m. EDT.

Despite the futures market reputation as an inconsistent indicator of what's to come in the next day's trading, investor eyes are likely glued to the screen for any signs of trouble following one of the worst single-day declines in market history.

The markets have recovered fairly quickly from their post-Brexit blues. U.S. indices, after rallying Wednesday to take back much of what they lost Friday and Monday, continued to turn toward greener pastures, with the Dow and the Nasdaq both up another 1.3% as of Thursday's close, and the S&P climbing nearly 1.4%.

June looks to have been a stagnant month overall for markets, however, as Brexit caused a blind sell-off across the board over fears of U.K. and European exposure, and anticipated interest rate hikes from the Federal Reserve gave investors jitters halfway through the month. 

Fortunately, Thursday also saw world markets continue to move past the potential economic repercussions of an independent U.K., with the Shanghai Composite Index up 0.58% Thursday and the Nikkei continuing to rally early Friday after finishing up 1.59% Thursday. The Hang Seng climbed 1.3% by Thursday's close, as well.

European stock markets rose for the third consecutive day following signs that policymakers will cut U.K. rates from historic lows to help stem the bleeding of a Brexit-related fallout. The FTSE 100 in London was up 2.27% on the day, while Germany's DAX gained 0.7%, and France's CAC 40 climbed 1%.

As for the commodity markets, crude futures enjoyed their largest gains in two months Wednesday, only to fall back by Thursday's close. Industry standard Brent crude futures for September delivery closed down 93 cents at $49.68 per barrel, but West Texas crude contracts for August delivery were up 25 cents, to $48.58 per barrel, around 9:30 EDT Thursday.

In market news, Tesla Motors (TSLA) shares were down close to 3% in after-hours trading after the company confirmed that regulators had opened a preliminary investigation into a fatal crash involving a Tesla Model S operating in "autopilot" mode.

Tesla said in a company blog post that it learned Wednesday evening the U.S. National Highway Traffic Safety Administration opened what the company called "a preliminary evaluation" into how the autopilot function performed during a crash, which happened in Florida in early May. 

And in other news on the market, following its failed $20 billion deal with Energy Transfer Equity (ETE) , six Williams Cos. (WMB) directors resigned Thursday after an attempt to oust CEO Alan Armstrong, including chairman Frank MacInnis, Reuters reported, citing an unidentified source with knowledge of the matter.
