There are two kinds of speculation; one is the invalid theory which begs that there is no connection between two factors under perception. On account of this examination in which the factors are my stock cost and the DJIA, The invalid theory is that there is no connection between my stock cost and the DJIA.

This suggests there is moderate positive connection between my stock cost and the DJIA. This affirms the elective theory which expressed that; there is a connection between my stock cost and the DJIA REFERENCES Soper, H.E., Young, A.W., Cave, B.M., Lee, A., Pearson, K. (1917).
