A review of market predictions and results for 2011, and a calibration for 2012 predictions (of 19 equity indices plus oil).

## Previously

One year ago the post “Revised market prediction distributions” presented plots showing the variability of various markets assuming no market-moving forces.

The follow-up post “Some market predictions enhanced some of those plots with predictions for 2011.

I did a review of *Future Babble* (which I think is apropos).

## Orientation

The distributions are an attempt to see the variability if there were no market-driving news for the whole year.

Another way of thinking of it is that if someone has a prediction for the year, then moving the distribution to center on the prediction gives a sense of what results should be expected if the assumptions of the prediction are exactly right.

The green lines in the plots indicate the starting point for the year. The red lines indicate the final point. The purple lines indicate predictions from various people.

## Methodology

- start with 8 or 9 years of returns
- take out an (excessively volatile) expected return at each point in time
- fit a GARCH(1,1) model
- simulate the garch model 250 trading days ahead starting with the current state (done 5000 times)

The simulation uses 50-day blocks. That is, for each simulated year 5 continuous blocks of length 50 are randomly selected from the standardized residuals from the garch model. With probability one-half the signs of all of the values in a block are switched — either all or none of the signs in the block are switched. This is meant to work around the autocorrelation in the residuals that is induced by fitting the overly rough expected returns.

## Data sources

The stock data comes from Yahoo.

The oil data comes from http://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=pet&s=rclc1&f=d

## Appendix R

The commands to do the computing and creation of the 2012 plots is in prediction_dist2.Rscript.

The commands to draw the 2011 plots is in yearend_2011.Rscript.

These depend on the functions defined in prediction_dist_funs2.R. Some of the functions have been revised from last year. In particular some functions have had the default for their `year` argument changed to 2012.

The `source` function can be used in R, for instance:

`source('http://www.portfolioprobe.com/R/blog/prediction_dist_funs2.R')`
