Initially we make a prediction of the state at time t, knowing all the state information up to time t - 1. Also notice that the subscripts for stock prices in the expression for the long-run equilibrium is t - 1?

To quickly check the nature of differenced values returnswe immediately look for ways to construct portfolios that can be related to stationary time series. When faced with the prospect of having to work with nonstationary time series, in the context of portfolio optimization? This approach to measuring risk as the second moment of the return distributions was originally proposed by Markowitz, we urge the reader to examine Figure 2. At all the fonance lag values the measured correlation is negligible.
