Correlations indicate how similarly a given stock has traded with this stock over each specified term. The closer a correlation is to 1, the more consistently the stocks moved in the same direction by the end of any given trading day. Inversely, stocks with a correlation closer to -1 have historically moved in opposite directions over the specified term. Stocks with correlations near 0 did not appear to be correlated, which means that they traded unpredictably relative to each other.
