NEW YORK (AP) — The value of the U.S. dollar has been on a tear for more than a year against everything from the British pound across the Atlantic to the South Korean won across the Pacific. The dollar is hovering close to its highest level in more than two decades against a key index measuring six major currencies. Many professional investors don’t expect the dollar to ease off anytime soon. Its rise makes an impact on nearly everyone, even those who will never travel beyond U.S. borders. The strength helps to limit inflation, but it can also hurt profits for many U.S. companies.
