The cost of euro/dollar options headed lower last week, as the dollar appreciated against the common currency in the face of volatile global equity markets. One-month implied volatility fell to 11.5% late Wednesday in New York from 12.7% a week earlier. However, traders said a stronger dollar was probably only a function of fx traders locking in profits to offset losses elsewhere in their portfolios last week, and that the euro is likely to continue to appreciate. "The dollar was oversold, the euro was overbought and people are locking in some gains," said one trader, adding, "it's not people reversing positions, more just squaring out." As proof, he said a common trade remained was to buy short-dated euro calls/dollar puts with strikes at USD1.02 and higher. Euro/dollar spot was at USD1.02 early last week before coming back under parity to USD0.99 by late Wednesday in New York.
