The ANO is used mainly for the DJIA and the SP500. The degree that it
can be used to predict other market indices depends on the correlation coefficient
between the DJIA and the index of interest. For the Russell 2000, the correlation
coefficient is around 0.91 which means that the DJIA and the Russell 2000 move
generally in the same direction but you should not expect to see the same percentage
change on a daily basis. Trading the ultra 3x shares is very risky and I do not
recommend using the forecast for this purpose.
