SEMINAR IN FINANCE Christian Helmenstein, Gabriel Lee (Biweekly Mondays) Monday, 07. April 1997 Martin Scheicher (University of Vienna, Department of Economics) "Modeling Polish Stock Returns" Abstract: This paper studies the econometric modeling of returns from the Warsaw Stock Exchange. We collect the statistical properties of returns and compare them to a sample from the German stock market. Then we evaluate the fit of two types of models: GARCH and Poisson Jump processes. We find that GARCH dominates the Jump model. Place: Institute for Advanced Studies, Stumpergasse 56, 1060 Vienna, SZ VI Time: 17:00h-18:30h Info: http://www.wsr.ac.at/ihs-html/fin/finsem.html =========================================================================

For comparison of methods submitted, the target variable series and performance metrics are specified (though not required). As an internationally-recognized independent forum since 1993, the Journal of Computational Intelligence in Finance (formerly NeuroVest Journal) serves as a central forum for the converging, multi-disciplined field of computational intelligence in finance. Papers published in the Journal are eligible for entry in an Annual Essay Award Contest. The Editorial Advisory Board of the Journal selects the best paper for which a cash award is presented each year. EDITORIAL ADVISORY BOARD E. Michael Azoff, Themisto Numerics Ltd. James E. Bowen, CompEngServ Ltd. Richard J. Bauer, Jr., St. Mary's University James F. Derry, Mgmt.

Skalak, University of Massachusetts Stephen Slade, Stern Bus. Sch., New York University Leon Sterling, University of Melbourne Manoel F. Tenorio, University of Purdue Halbert White, University of California at San Diego SPECIAL TOPIC Improving Generalization for Nonlinear Financial Forecasting Models PUBLICATION DATE November 1997 PAPER SUBMISSION DEADLINE June 30, 1997 MOTIVATION The critical issue in applying neural networks and other data-driven forecasting systems is generalization, the performance on data not used for training. The key to generalization behavior is model complexity. Too simple a model cannot approximate the true relationship, and overly complex models adjust to the noise in the data. Nearly all financial applications of nonparametric models (such as neural networks and genetic algorithms) vary model complexity by adjusting the number of parameters. This special issue intends to highlight other methods to improve generalization, in particular regularization (e.g., neural network weight decay and smoothing) and techniques for combining models. Of particular interest are nonlinear methods including neural networks, genetic algorithms, nearest neighbor networks, polynomial networks, fuzzy logic, and hybrids. Nearly all studies apply cross-validation to select the best model. Alternatives to cross-validation include 'analytical' selection rules such as Akaike's Information Criterion, Schwartz's Information Criterion, and a number of others. Of particular interest are the statistical properties (i.e., bias and variance) of model selection methods in estimating out-of-sample performance. DATA, TARGET VARIABLES and PERFORMANCE METRICS Data: daily prices of a financial time series (see below) Target Variable: the relative difference in percent (RDP) between today's closing price and the price five (5) days ahead Performance Metrics: MSE (target). nRMSE and DS (to be used in the analysis). Participants are encouraged to use the forecast data, target variable and performance metrics specified for this special issue, which are available on the Web to those who submit a satisfactory abstract (including brief biography) as outlined below. Participants are not be restricted regarding the data used as inputs to their predictors. Especially interesting original methods using other forecast data, target variables and performance metrics will also be considered. The forecast series is derived from daily closing prices for a financial time series. The target variable is the relative difference in percent (RDP) between today's closing price and the closing price five (5) days ahead. The date, the underlying price series and the target variable series are all provided in the downloadable data file. The target metric is the MSE. Also, authors' analysis should include the normalized RMSE (RMSE normalized using the standard deviation of actual RDP values), and Directional Symmetry (percentage of correctly predicted directions with respect to the target variable). The forecast data provided is separated into in-sample (10 years of daily data) and out-of-sample (2 years of daily data) sets. Participants are not restricted regarding the data used as input to their predictors. However, all data used should be disclosed in the paper presentaton, including the details of all techniques and formulas used to pre-process the data. Details on the predictor and the methods used for improving generalization should be presented in the paper. FORECAST HORIZON AND RE-TRAINING Participants should test performance of their predictors over the entire two-year out-of-sample dataset. Of interest are results of analyses and performance of predictors over the entire two-year prediction period: (1) without re-training and (2) with re-training (optional). The results from (1) and (2) can be useful for estimating the limits of the forecasting horizon for the prediction methods presented.
