DIA traded on the 4th of July, 2007?

  1. I thought 7/4/2007 was a holiday and all US markets closed. But the historical data on Yahoo Finance showed the following trading results for DIA on 7/4/2007:

    Jul 4, 2007 135.27 135.27 135.27 135.27 7,521,000 125.51

    Is this right? Does this mean that all historical data of DIA would be a day off since 7/4/2007?

    Is there any other source for historical stock data?

    Thanks for any suggestions.
