In finance, statistical arbitrage (often abbreviated as Stat Arb or StatArb) is a class of short-term financial trading strategies that employ mean reversion models involving broadly diversified portfolios of securities (hundreds to thousands) held for short periods of time (generally seconds to days). A Multi-factor Adaptive Statistical Arbitrage Model Wenbin Zhang1, Zhen Dai, Bindu Pan, and Milan Djabirov Tepper School of Business, Carnegie Mellon Unversity 55 Broad St, New York, NY 10005 USA Abstract This paper examines the implementation of a statistical arbitrage trading strategy based on co- ! 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. These models introduce uncertainty stemming from multiple sources. The Arbitrage Pricing Theory operates with a pricing model that factors in many sources of risk and uncertainty. that can be further improved. ! 0000032255 00000 n
In finance, statistical arbitrage (often abbreviated as Stat Arb or StatArb) is a class of short-term financial trading strategies that employ mean reversion models involving broadly diversified portfolios of securities (hundreds to thousands) held for short periods of time (generally seconds to days). Arbitrage Portfolio Theory (APT) came along after CAPM as a multifactor model to explain returns. Thus, it allows the selection of factors that … View Note 4 - Expected Returns .pdf from MSCF 46912 at Carnegie Mellon University. APT model is a multi-factor model.

The Arbitrage Pricing Theory (APT) was developed in the 1970’s and, like the CAPM, relates the expected return on securities or portfolios to risk. Arbitrage pricing theory (APT) is a multi-factor asset pricing model based on the idea that an asset's returns can be predicted using the linear … 0000031871 00000 n
So, the expected return is calculated taking into account various factors and their sensitivities that might affect the stock price movement. ! 0000002604 00000 n
APT explains returns under the construct where: Multiple risks with an excess return above the risk free rate of return can be priced. The portfolio should have duration close to zero No systematic interest rate risk exposure. 0000005922 00000 n

In this model, the market portfolio serves as one factor and state variables serve as additional factors. First, many factor-based statistical arbitrage strategies seem to be unclear about the factor selection process. 0000008233 00000 n

Any security or portfolio has its own beta coefficient to each of the priced risk variables in the model. 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 2.1.

The model-derived rate of return will then be used to price the asset … other than using the price data alone. CAPM, on the other hand, limits risk to one source – covariance with the market portfolio. trailer
Static arbitrage trading based on no-arbitrage DTSMs For a three-factor model, we can form a 4-swap rate portfolio that has zero exposure to the factors. Download PDF. Where CAPM is a single-factor model that relates investment returns to the return on the overall market, APT is a multifactor model. An arbitrage opportunity exists if an investor can construct a _____ investment portfolio that will yield a sure profit. 0000003344 00000 n
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. The Intertemporal Capital Asset Pricing Model developed in Merton (1973a) combined with assumptions on the conditional distribution of returns delivers a multifactor model.

Time Series Analysis 2. 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.

Multi-Factor Statistical Arbitrage ● Using only price/returns data creates unstable clusters that are exposed to market risks and don’t persist well over time. Papers from arXiv.org. The APT offers analysts and investors a multi-factor pricing model for securities, based on the relationship between a financial asset’s expected return and its risks. The theory was first postulated by Stephen Ross in 1976 and is the basis for many third-party risk models. 0000008932 00000 n
A multifactor model is a financial model that employs multiple factors in its calculations to explain asset prices. Statistical Arbitrage Strategies can also be designed using factors such as lead/lag effects, corporate activity, short-term momentum etc. 0000002057 00000 n
In finance, arbitrage pricing theory ( APT) is a general theory of asset pricing that holds that the expected return of a financial asset can be modeled as a linear function of various factors or theoretical market indices, where sensitivity to changes in each factor is represented by a factor-specific beta coefficient. APT explains returns under the construct where: Multiple risks with an excess return above the risk free rate of return can be priced. APT doesn’t define the risk factors nor it specifies any number. 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.

Factor Models are financial models that incorporate factors (macroeconomic, fundamental, and statistical) to determine the market equilibrium and calculate the required rate of return. The factor surprise is defined as the difference between the realized value of the factor and its consensus predicted value. Assets are priced such that there are no arbitrage opportunities. 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. 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.
