Chapter 12 Tests of multifactor pricing models, volatility bounds and portfolio performance
Ferson, Wayne E. - 2003
Three concepts: stochastic discount factors, multi-beta pricing and mean-variance efficiency, are at the core of modern empirical asset pricing. This chapter reviews these paradigms and the relations among them, concentrating on conditional asset-pricing models where lagged variables serve as...

Jump factor models in large cross‐sections
Li, Jia; Todorov, Viktor; Tauchen, George Eugene - In: Quantitative economics : QE ; journal of the … 10 (2019) 2, pp. 419-456
We develop tests for deciding whether a large cross‐section of asset prices obey an exact factor structure at the times of factor jumps. Such jump dependence is implied by standard linear factor models. Our inference is based on a panel of asset returns with asymptotically increasing...

Recalcitrant betas : intraday variation in the cross-sectional dispersion of systematic risk
Andersen, Torben; Thyrsgaard, Martin; Todorov, Viktor - In: Quantitative economics : QE ; journal of the … 12 (2021) 2, pp. 647-682
We study the temporal behavior of the cross-sectional distribution of assets' market exposure, or betas, using a large panel of high-frequency returns. The asymptotic setup has the sampling frequency of returns increasing to infinity, while the time span of the data remains fixed, and the...

Changes in the span of systematic risk exposures
Liao, Yuan; Todorov, Viktor - In: Quantitative economics : QE ; journal of the … 15 (2024) 3, pp. 817-847
We develop a test for deciding whether the linear spaces spanned by the factor exposures of a large cross-section of assets toward latent systematic risk factors at two distinct points in time are the same. The test uses a panel of asset returns in local windows around the two time points. The...

Restatement of the I-O coefficient stability problem
Dobrescu, Emilian - In: Journal of economic structures : JES; the official … 2 (2013), pp. 1-67
The capacity of input-output tables to reflect the structural peculiarities of an economy and to forecast, on this basis, its evolution, depends essentially on the characteristics of the matrix A matrix of I-O (or technical) coefficients. However, the temporal behaviour of these coefficients is...

Technical analysis accuracy at Macedonian Stock Exchange
Ivanovski, Zoran; Ivanovska, Nadica; Narasanov, Zoran - In: UTMS journal of economics / University of Tourism and … 8 (2017) 2, pp. 105-118
The main task of this paper is to determine accuracy of some of widely used technical analysis techniques for MBI-10 stocks price forecast at MSE. We are testing accuracy of several technical analysis techniques: MACD (Moving-Average Convergence/Divergence), RSI (Relative Strength Index),...

Expectations concordance and stock market volatility : Knightian uncertainty in the year of the pandemic
Frydman, Roman; Mangee, Nicholas - In: Journal of risk and financial management : JRFM 14 (2021) 11, pp. 1-13
This study introduces a novel index based on expectations concordance for explaining stock-price volatility when novel … market volatility. Lower expectations concordance produces a stabilizing effect wherein the offsetting views reduce market … volatility. The empirical findings hold for ex post and ex ante measures of volatility and for OLS and GARCH estimates. …
