Uncertainty in the Black-Litterman model : a practical note

Fuhrer, Adrian; Hock, Thorsten - 2019 - Version: July 15, 2019

. It allows the specification of views and an uncertainty about these views, which are combined with equilibrium returns … process. In the Black-Litterman model, however, uncertainty about the equilibrium returns is specified with an overall scalar …-Litterman model to allow the specification of uncertainty in a flexible way not only in individual views, but also in the equilibrium …

Return and risk-return ratio based momentum strategies : a fresh perspective

Chia Rui Ming Daryl; Lim Kai Jie Shawn; Chan Ho Yan Sabrina - In: Journal of finance and investment analysis 2 (2013) 1, pp. 1-13

In this study, we contribute to existing literature on momentum strategies by assessing a modified version of risk-return ratio based security selection criterion in an untested market – the KOSPI 200 over June 2006 to June 2012. Besides conventional risk-return ratios such as the Sharpe...

Asset pricing and consumption-portfolio choice with recursive utility and unspanned risk

Kraft, Holger; Seiferling, Thomas; Seifried, Frank Thomas - 2014 - First version: March 6, 2014; this version: June 1, 2014

We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/representative agent can be characterized by a specific semilinear partial differential...

Common risk factors in equity markets

Atanasov, Victoria - 2014 - This version: May 26, 2014

Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity returns. We propose a new factor, termed "the global consumption factor", to explain the patterns in risk premiums on international equity markets. We identify this factor as the...

Low-beta investment strategies

Korn, Olaf; Kuntz, Laura-Chloé - 2016 - This version: October 2016

This paper compares several investment strategies designed to exploit the low-beta anomaly. Although the notion of buying low-beta stocks and selling high-beta stocks is natural, a choice is necessary with respect to the relative weighting of high-beta stocks and low-beta stocks in the...

Simulating the market coefficient of relative risk aversion

Azar, Samih Antoine; Karaguezian-Haddad, Vera - In: Cogent economics & finance 2 (2014) 1, pp. 1-7

In this paper, expected utility, defined by a Taylor series expansion around expected wealth, is maximized. The coefficient of relative risk aversion (CRRA) that is commensurate with a 100% investment in the risky asset is simulated. The following parameters are varied: the riskless return, the...

Cash flow and discount rate risk in up and down markets : what is actually priced?

Botshekan, Mahmoud; Kräussl, Roman; Lucas, André - 2010

We test whether asymmetric preferences for losses versus gains as in Ang, Chen, and Xing (2006) also affect the pricing of cash flow versus discount rate news as in Campbell and Vuolteenaho (2004). We construct a new four-fold beta decomposition, distinguishing cash flow and discount rate betas...

Positive alpha and negative beta (a strategy for counteracting systematic risk)

Noddeboe, Erik Sonne; Faergemann, Hans Christian - In: International Journal of Financial Studies : open … 3 (2015) 4, pp. 431-450

Undiversifiable (or systematic risk) has long been an enemy of investors. Many countercyclical strategies have been developed to counter this. However, like all insurance types, these strategies are generally costly to implement, and over time can significantly reduce portfolio returns in long...

Asymmetric beta comovement and systematic downside risk

Jondeau, Eric; Zhang, Qunzi - 2014

In this paper, we document evidence that downside betas tend to comove more than upside betas during a financial crisis, but upside betas tend to comove more than the downside betas during financial booms. We find that the asymmetry between Downside-Beta Comovement and Upside-Beta Comovement is...
