Historical performances don't support future performance prediction.
That's why stock prices are not predictable.

I developed a program for Stock Market Forecasting based on approach:
Kovalerchuk B., Vityaev E. Data Mining in Finance:
Advances in Relational and Hybrid methods. Kluwer Academic
Publishers, 2000, p.308.
years I trained the program on S&P500
emini, using data from
CME. Results are presented on my exclusive website on "Stock Market
Forecasting". The address of this site may be send by request. The
Annual Gross Gain was more then 150%.

interesting how many people expect from NN models than classical
methods better result but in my humble opinion the problem is more
theoretic & the question of effecitivity of information-diffusion in

I'd be very interested to know some rough annual Return On Margin (ROM) numbers for your S&P model, along with any others you care to share.
My own work using a high end NN as the primary model development tool returns about 300% annual ROM for the S&P.

A colleague and I have beeen using proprietary data mining techniques to predict the short-term (day to day) movements of futures for the S&P 500 and more than a dozen related commodity, stock, and bond markets. The key issue is not "How accurately you can predict up versus down days?" but rather "Can you make predictions and use them with a trading strategy to make money with minimal risk?".
As with any data mining problem, the effective solution involves
having the right data base, formulating the problem correctly, and
using the right data mining tool. The first two issues require domain
knowledge best provided by a successful hedge fund trader. The latter
is crucial: I have tried many out-of-the-box data mining algorithms
(PLS, neural nets, various decision trees, ...) and found that
generally they cannot predict the futures markets significantly better
than chance. Our proprietary method, specifically tuned to this kind
of problem, does.

The knowledge discovery activities on S&P 500 should have two main directions:
1) Model should predict not S&P 500 itself, but the behavior of real successful expert.
2) Solutions for brokerage house. Model ought to generate unifying hypothesis on S&P 500 based on stock market gamblers move, since the actions of the client is well known to the broker.

The condition is probably, as with all data mining activities, to get the right data to describe what influences the things you want to predict.
(ties in nicely with the previous poll on methodologies by the way, avoiding diving into data headfirst without first giving some thought on the business issue at hand)
And as John Elder mentions: you don't have to get it right 100% of the time, as long as you can improve it enough to make you money ;-)

In my research and consulting for investors, the S&P 500 Index future (CME) is one of the best major financial instruments for predictive modeling, at least in the short term.
Annual return on margin results are typically in a range of 300% to 400% for a trading strategy based on detecting short term moves of 2 or 3 days. Other
commodities such as the Euro, Yen, T-Bills and most of the agricultural futures are much harder to model effectively. I do not have a good theory that explains this difference.
Effective model development for the S&P is a rather complex undertaking and requires the development of multiple overlayed models, dozens of carefully selected independent variables and the use of high
end data mining software.

It's tough, but doable. Building financial investment models is the main work Elder Research, Inc. does. We've found that markets, or their directions, can be predicted enough better than randomly to make it worthwhile.

Predicting Stock Market
I frequently see references for various data mining programs that can
successfully predict stock market indices such as S&P 500, but it is
hard to judge their success, especially given recent volatility. What
is your opinion (and experience) -- can data mining methods predict
S&P 500 or other stock market indicators?
