Futures for the S&P 500 index, Nasdaq 100 and Dow Jones industrial average rose slightly in late trading. That follows gains of more than 1% for the S&P 500 index, Nasdaq composite and Dow industrials, all closing within 1% of all-time intraday highs. Apple (AAPL), as the most valuable company and largest component of all three major averages, will have a lot to say about whether they do set new record levels Tuesday as the tech titan unveils its latest iPhone models.
