AUTHOR'S NOTE: This post has been updated to reflect that the U.K. has voted to leave the European Union.
Nearly every market move over the last two weeks has been attributed to the upcoming British referendum on whether the United Kingdom should remain with or leave the European Union.
A poll showed Brits might want to leave? Down go stocks. Then it looked like the U.K. would stay in the political and economic bloc? Here's 200 points to the upside for the Dow Jones industrial average.
Now that the U.K. has officially voted in favor of leaving, markets are going wild.
And it's not just trading desks who cared about Thursday's referendum. Federal Reserve Chair Janet Yellen said earlier this month that a British exit from the EU "could have consequences in turn for the U.S. economic outlook."
