Thursday, Aug. 15. Mark this date on your calendar.

A very good source of mine says a report from Inspector General Michael Horowitz of the Justice Department on spying and other nastiness during the 2016 presidential election will be out by then. And, I believe, it will be a blockbuster.

So investors and all Americans might want to fasten their seat belts starting that week. It could be a rocky ride for the markets from then into the fall.
