(python)

I'm trying to print out covariance matrix of the simple returns of 5 stocks.

I've got the returns of all stocks and I tried to use numpy.cov but if I put more than 2 arguments into it , it didn't work.

Cov = np.cov(BHP_return.T,CSL_return.T,NAB_return.T,REA_return.T,WOW_return.T)

this is the code that I used.

I would appreciate if you could find the right code for this.
