I have been taking a look at the DJI, Nasdaq and S&P500 intraday trend for the past weeks. Please refer to attachement. I notice that all 3 indexes are having almost the same trend. These indexes are using different stocks as their base. Why are they having similar intraday trend ? Your comment is much appreciated. Thanks.
P.S. - The date should be 8 Sep and 9 Sep instead of 8 Aug and 9 Aug.
