Paul Tudor Jones, once fittingly observed, "Fundamentals might be good for the first third or first 50 or 60 percent of a move, but the last third of a great bull market is typically a blow-off, whereas the mania runs wild and prices go parabolic... There is no training, classroom or otherwise, that can prepare for trading the last third of a move, whether it's the end of a bull market or the end of a bear market."
In today's policy-driven system, where fundamentals have been melded and supplanted by the hand of the Fed, the relative outperformance by our own monetary authorities has not only buttressed our equity markets relative to the world, but also the dollar. This dynamic has been in place since the embers of the U.S. financial crisis in 2008, blew across the pond that summer and ignited a firestorm around the world that fall. In another counterintuitive twist of fate -- despite our clear culpability in setting the world ablaze, we had a head start of working and digging the fire lines, that eventually brought the economic disaster under control -- first. The "new normal" posited directly following the financial crisis, looked a whole lot like the old normal from the late 1990's.

With the U.S. dollar index now flirting with the topside of it's long-term range, a break above might imply that the move was not the last third -- but a new game altogether. Considering the juxtaposition of the Fed withdrawing its fire brigade as the rest of the world turns up their hoses -- how likely does that seem? 
At face value -- and from an "old school' fundamental perspective -- quite likely. However, as we alluded to before, since the financial crisis, the doctrines that have instigated the reach for yield and differential of capital flows toward the U.S., have been framed relative to what the balance of the world's major central banks were doing to support their own economies. With the ECB now finding religion and the Chinese seemingly not far behind, the shear stresses that have engendered a positive skew in the US equity markets and dollar should diminish as the Fed walks away. Moreover, we find it noteworthy that the conventional wisdom in the euro today now echoes the expectations from earlier in the cycle, that the U.S. dollar would be pressured lower by Fed policy.
From a broader macro point of view, it appears more likely that the dollar is completing "the last third of the move", rather than a return to conditions of the late 1990's that an upside range break would imply.
