What to Watch This Week: Yellen Testimony, Brexit Vote, FedEx Earnings

For the week of June 20, investors await testimony from Federal Reserve Chair Janet Yellen, a critical Brexit vote and a slew of corporate earnings. On Tuesday, Yellen's semi-annual testimony in front of the Senate Banking Committee takes place. On the docket? The outlook for the U.S. economy, the pace of rate hikes going forward and don't be surprised if Brexit is top of mind. That's because the landmark Brexit vote takes place next Thursday - UK citizens will vote on whether or not to remain in the European Union.
