Opening Bell: U.S. Stocks Slip as Investors Flood Save-Havens; Walgreens Earnings Shine

U.S. stocks moved lower on Wednesday, as Brexit fears pushed investors into safe-haven assets. Japan's 20-year government bond yield dipped into negative territory for the first time ever. Gold prices hit a two year high, as investors ditched risky assets. Plus, oil prices dipped to a two-month low on fears a Brexit could ding demand. Meanwhile, Walgreens Boots Alliance (WBA) - Get Report reported better-than-expected third quarter earnings and raised the lower end of its full-year earnings forecast. Earnings of $1.18 a share beat estimates of $1.14 a share. The company's acquisition of Rite Aid (RAD) - Get Report is set to close in the second half of 2016. Finally, investors are gearing up for the 2pm Eastern release of the minutes of the Federal Reserve's June meeting, when the central bank left interest rates unchanged. While this meeting was before the Brexit vote, investors hope to gain more insight on whether the dismal May jobs report was a fluke or a more worrisome sign about the labor market.
