(Harvest) Global macro traders look for outliers. The good ones have a disciplined approach to review and process lots of cross-market relationships looking for the few that may be out of place. These are the relationships that need capital and for those that can provide the funds, there is a reward.
Think of these cross-market outliers as tremors that may indicate something more going on, an indication of a greater potential financial dislocation. This is especially the case when there it may occur in markets that are supposed to be liquid like the foreign exchange markets.
