The US dollar may be bottoming based on several factors:
1) Valuation measures like the Big Mac Index and OECD measures imply the dollar is undervalued by 30-35%
2) Increases in US oil and gas production from shale could reduce US imports and improve the trade balance by a third
3) A turnaround in US economic confidence and growth could support a rise in the dollar through upward revisions to interest rate expectations
