Now of course, the really busy weeks always come unexpectedly (such as when Japan had its nuclear crisis last year, and the entire world was riveted by every twist and turn for days), but in terms of scheduled events, the coming days are like nothing we've seen before.

We've got big-time economic events, earnings, important central bank meetings, and oh yeah, even elections that have implications for the entire world.

So, let's preview the sprint.

Monday, April 30 is probably going to be the quietest day, but even that will be stacked. On the US economy front, we've got fresh data for Personal Income & Spending, the Chicago PMI Report, and the Dallas Fed Manufacturing Outlook Survey. There's also a boatload of earnings that day, as there will be every other day next week.
