Stocks, stuck in their own zigzag pattern, remain vulnerable to the whims of unusually volatile currencies in the week ahead.
As financial markets adjust to the Fed's latest guidance on rates, traders will be hyper-focused on any potential clues in economic data or central bank speak that would help clarify timing of its first hikes.
Stocks surged in the past week for the first weekly gain in a month, and it was no coincidence the dollar saw its first decline in five weeks. The dollar index lost more than 2.5 percent but only after an extraordinary amount of intraday volatility. Treasury yields moved lower, also transitioning to a new Fed forecast.
