ASIAN STOCKS: Asian stocks were the first to react to the vote and they took huge losses. Japan's Nikkei 225 plunged 7.9 percent after a wild day of trading, its biggest loss since the financial crisis.
EUROPEAN STOCKS: European stocks also tumbled, although indexes on the European continent took larger losses than British ones. France's CAC 40 lost 8 percent and Germany's DAX fell 6.8 percent. Britain's FTSE 100 fell 3.1 percent, with homebuilders suffering huge losses.
CRUDE OIL: Oil prices fell almost 5 percent as investors worried the move will slow down global economic growth. Benchmark U.S. crude dropped $2.47 to $47.64 a barrel in New York.
THE EURO: While Britain never adopted Europe's common currency, the vote to leave got investors worried that the EU could weaken as an economic bloc if other countries also decided to leave, or to postpone joining. The euro fell to $1.1121 from $1.1351.
WINNERS:
GOLD: The most famous "safe" investment of all, gold made its biggest jump in months. Gold is now trading at its highest price since July 2014. The price of an ounce of gold rose $59, or 4.7 percent, to $1,322. That followed five days of declines as investors hoped that Britons would vote to remain in the EU.
BONDS: Investors bought U.S. government bonds, which are considered an ultra-safe investment that tends to hold its value and is easy to buy and sell. The yield on the 10-year U.S. Treasury note plunged to 1.56 percent from 1.75 percent a day earlier, a huge move. Bond yields are used to set interest rates on many kinds of loans including mortgages.
HIGH-DIVIDEND STOCKS: Stocks that are similar to bonds also did well. Utility companies and phone companies pay big dividends compared to most other kinds of stocks. That means investors get more cash and the stocks are more stable. Utility stocks were the only one of the 10 sectors in the S&P 500 index to rise on Friday.
THE DOLLAR: The dollar, which is already very strong relative to other currencies, got even stronger. The ICE U.S. Dollar index, which measure the dollar against a group of other world currencies, rose about 2 percent.
