Below are the current forecasts for 25 years of the S&P ETF SPY and the historical S&P index GSPC going back 50 years.
I though it might be instructive to add the extra 25 years of S&P price action into the mix to see if it aligned more or less with the SPY forecast. It turns out that's pretty much the case although the GSPC is a bit more constrained in the range of the outlier scenarios and the current risk outlook.
Both models have very similar targets 18 weeks out. Its just that the SPY outlook is considerably more volatile.
