Markets, whether bonds, commodities, currencies or equities will always have price gyrations as a normal course of action. This presents difficulties maintaining a course in challenging conditions, but it can also allow for tremendous opportunities to buy at discount.
When markets fell considerably in 1998 and 2008, it was a correction for structural as well as economic concerns. This is not one of those times. As the airwaves and internet fill with thousands of voices, with all sorts of differing opinions, it is wise to listen to those that are the industries best and most experienced.
Dave and I would recommend that if interested, read and/or listen to the following clips about the market movements.
