If you go to Yahoo and compare any one of these 107 stocks to the SP500 on Yahoo graphs, you will see there is a very strong similarity between them.   For the stocks listed below, check them out at one day, five days and one month compared to the SP500, as that is nearest what I was calculating for.  However, it is also interesting to view them at other time intervals too, such as three months, one year etc.

And this much shorter list is those stocks which are very alike to the SP500 but opposite.  Compare them as well, to the SP500.  In my scoring system, all of these stocks above are so correlated as to score better than 80, except for the ones below which score less than -80.
