INTRODUCTION
Financial engineering is a rapidly expanding
research area. Trading systems based on com-
putational intelligence techniques for financial
asset management, notably in the areas of equities
trading and risk management for derivatives like
options and swaps has received considerable in-
terest from both researchers and financial traders.
Neural networks (NN) have been used extensively
for market forecasting (White, 1988; Chiang et al.,
1996). More recently, time-delay, recurrent and
probabilistic NNs have been used to analyze the
predictive capability of the networks using “live

A Novel Fuzzy Associative
Memory Architecture for Stock
Market Prediction and Trading
ABSTRACT
In this paper, a novel stock trading framework based on a neuro-fuzzy associative memory (FAM) ar-
chitecture is proposed. The architecture incorporates the approximate analogical reasoning schema
(AARS) to resolve the problem of discontinuous (staircase) response and ineffcient memory utilization
with uniform quantization in the associative memory structure. The resultant structure is conceptually
clearer and more computationally effcient than the Compositional Rule Inference (CRI) and Truth Value
Restriction (TVR) fuzzy inference schemes. The local generalization characteristic of the associative
memory structure is preserved by the FAM-AARS architecture. The prediction and trading framework
exploits the price percentage oscillator (PPO) for input preprocessing and trading decision making.
Numerical experiments conducted on real-life stock data confrm the validity of the design and the per-
formance of the proposed architecture.
