The major indexes are firmly higher this afternoon as rate-hike expectations ease and Treasury yields cool, with the Dow Jones Industrial Average (DJI) up roughly 670 points and on track for its best single-day percentage gain since Aug. 4, while the Nasdaq Composite Index (IXIC) and S&P 500 Index (SPX) sport healthy gains as well.

Investors are also unpacking the Institute for Supply Management's (ISM) August reading, which rose to a higher-than-expected 55.4 from 54.1 in July, signaling continued economic expansion. Weekly jobs data and the latest trade deficit update remain in focus, while CME's FedWatch tool now shows a 50.4% chance of a rate hike in less than two weeks.
