# multi factor statistical arbitrage model

Any security or portfolio has its own beta coefficient to each of the priced risk variables in the model. In this model, the market portfolio serves as one factor and state variables serve as additional factors. APT explains returns under the construct where: Multiple risks with an excess return above the risk free rate of return can be priced. A multi-factor model with dynamic factors Let yr be a vector of N asset excess returns (rates of return minus a riskfree rate). 0000011295 00000 n Fundamental factor models. 0000009543 00000 n Any security or portfolio has its own beta coefficient to each of the priced risk variables in the model. These models introduce uncertainty stemming from multiple sources. CAPM Arbitrage Pricing Theory (multi-factor risk Where CAPM is a single-factor model that relates investment returns to the return on the overall market, APT is a multifactor model. A multifactor model is a financial model that employs multiple factors in its calculations to explain asset prices. This latter approach is referred to as a multi-factor Statistical Arbitrage model. The portfolio selection methodologies include K-means clustering, graphical lasso and a combination of the two. APT model is a multi-factor model. For those who aren't familiar with the paper, the method in the paper (which I'm assuming is similar to other Statistical Arbitrage strategies) is to use the residuals of some factor model (whether it be by PCA or fundamental factors) as the signals to trade. startxref Asset returns are described by a factor model. The factor surprise is defined as the difference between the realized value of the factor and its consensus predicted value. The theory was first postulated by Stephen Ross in 1976 and is the basis for many third-party risk models. 0000031314 00000 n 0000010175 00000 n Factor Models are financial models that incorporate factors (macroeconomic, fundamental, and statistical) to determine the market equilibrium and calculate the required rate of return. 0000031871 00000 n 0000008233 00000 n ... penny stocks and stocks in bankruptcy. The Intertemporal Capital Asset Pricing Model developed in Merton (1973a) combined with assumptions on the conditional distribution of returns delivers a multifactor model. 0000003435 00000 n Wenbin Zhang, Zhen Dai, Bindu Pan and Milan Djabirov. Arbitrage Portfolio Theory (APT) came along after CAPM as a multifactor model to explain returns. I've recently read Avellaneda & Lee which seems to be widely recommended as an introduction to Statistical Arbitrage methods in trading. The Intertemporal Capital Asset Pricing Model developed in Merton (1973a) combined with assumptions on the conditional distribution of returns delivers a multifactor model. The fair value of the portfolio should be relatively at over time. You can think about like if many stocks available, as we talked about, remember our example going gambling and to [inaudible], firm specific risk is always going to be able to be diversified away by just adding more stocks to the portfolio. A typical multi-factor model is K y,=p.,+ c Pk.fkr+&r, k-1 (1) where pI is the N x 1 vector of expected excess returns (or risk premia), K is 0000022245 00000 n Arbitrage pricing theory is the foundation of multi-factor models, models which attempt to explain the expected return as a function of the risk-free rate plus the product of different components of systematic risk such as inflation rate, business cycle stage, central bank discount rate, etc. Avellaneda and Lee A Multi-factor Adaptive Statistical Arbitrage Model. !

Abstract: This paper examines the implementation of a statistical arbitrage trading strategy based on co-integration relationships where we discover candidate portfolios using multiple factors rather than just price data. Arbitrage Pricing Theory (APT) is a multi-factor asset pricing theory using various macroeconomic factors. ● By incorporating other stock time-series data like fundamentals (P/E ratio, revenue growth, etc. WHAT WE WILL LEARN In Chapter 6, how a single-factor model could be used to estimate the 2 components of risk (“market” and “firm-specific”) for a security. View Note 4 - Expected Returns .pdf from MSCF 46912 at Carnegie Mellon University. A _____ portfolio is a well-diversified portfolio constructed to have a beta of 1 on one of the factors and a beta of 0 on any other factor. As used in investments, a factor is a variable or a characteristic with which individual asset returns are correlated. .

First, many factor-based statistical arbitrage strategies seem to be unclear about the factor selection process. On this page, we discuss the an example of a macroeconomic factor model formula and illustrate how to use a macroeconomic factor model once the parameters have been estimated. The APT aims to pinpoint the fair market price of a security that may be temporarily incorrectly priced. 0000010575 00000 n A multi-factor model is a financial modeling strategy in which multiple factors are used to analyze and explain asset prices. other than using the price data alone. 0000002057 00000 n [ Music ] >> Alright, arbitrage pricing theory and multi-factor models.

So, the expected return is calculated taking into account various factors and their sensitivities that might affect the stock price movement. APT doesn’t define the risk factors nor it specifies any number. 0 The purpose of this paper is to test the multi-factor beta model implied by the generalized arbitrage pricing theory (APT) and the Adaptive Multi-Factor (AMF) model with the Groupwise Interpretable Basis Selection (GIBS) algorithm, without imposing the … Thus, it allows the selection of factors that affect the stock price largely and specifically. ! APT doesn’t define the risk factors nor it specifies any number.
