Investors will lock in Friday on speeches by the Federal Reserve’s top policy-makers, Yellen’s speech is scheduled for 1 PM Eastern Time. Warming up traders for the boss, four other Fed officials take the stage before her: Fed No. 2 Stanley Fischer, Fed Gov. Jerome Powell, the Chicago Fed’s Charles Evans and Richmond’s Jeffrey Lacker. Yellen will likely confirm the same message we have heard this week, that a hike soon is appropriate and three hikes are still expected in 2017.
