Market anomalies are predictable patterns in financial markets that contradicts the efficient market hypothesis and random walk theory. Several have been documented ever since emergence of behavioural finance early 90s. The Turn Month anomaly is a well-known pattern has resonates lot controversy finance. Advocates effect contends stock returns tend to be higher at last few trading days month wh...
We report a statistical analysis of the Island ECN (NASDAQ) order book. We determine the static and dynamic properties of this system, and then analyze them from a physicist’s viewpoint using an equivalent particle system obtained by treating orders as massive particles and price as position. We identify the fundamental dynamical processes, test existing particles models of such markets against...
Recently, the Support Vector Regression (SVR) has been applied in the financial time series prediction. The financial data are usually highly noisy and contain outliers. Detecting outliers and deflating their influence are important but hard problems. In this paper, we propose a novel “two-phase” SVR training algorithm to detect outliers and reduce their negative impact. Our experimental result...
The third section concerns potential improvements to the system in the future. In particular, reference is made to the translation of financial reporting documents using Extensible Business Reporting Language (XBRL), taking advantage of another PwCSYSTRAN joint project which is pioneering the use of XBRL in a web-based service for translating financial documents, and a further XBRL initiative u...

stock market to take the correct buy/sell/hold decisions. The results obtained from the proposed fuzzy logic model were satisfactory but not accurate. A fuzzy tuning methodology was introduced to enhance the accuracy of the decisions. The tuning methodology which uses genetic algorithms is presented also in this paper. A multi agent framework is proposed for the implementation of the system. Ex...
Abstract. Definitions from the theory of point processes are recalled. Models of intensity function paramaterization and maximum likelihood estimation from data are explored. Closed-form log-likelihood expressions are given for the Hawkes process, Autoregressive Conditional Duration(ACD), and Log-ACD models. The Autoregressive Conditional Intensity model is also discussed. Data from the symbol ...
