Alternative Beta Strategies in Commodities

SSRN Electronic Journal, 2013
Alternative beta strategies can serve a variety of different investment objectives, which may include reducing volatility or achieving tilts to systematic risk exposures. It is therefore essential for investors to examine whether these strategies meet their own investment objectives and risk-taking preferences.

Alternative Beta Strategies

SSRN Electronic Journal, 2016
Market capitalization weighted indices have historically been the most widely used strategies to achieve a passive exposure to equities markets, or capture equities beta. However, we have seen a surge of strategies called alternative betas (or sometimes “smart betas”) that, using different index construction methodologies, aim to provide a passive ...

Beta-Blockade as an Alternative to Cardioplegia

The Thoracic and Cardiovascular Surgeon, 1998
As an alternative to cardioplegic arrest, "cardiac surgical conditions" (i.e. a flaccid heart which facilitates surgery) have been created by continuously perfusing the coronary arteries with normothermic blood and suppressing myocardial chronotropy and inotropy with the ultra-short acting beta-blocker esmolol.

Alternative beta-titanium alloys for orthodontic wires

Dental Materials, 1987
Abstract Ti-11.5Mo-6Zr-4.5Sn metastable beta-titanium alloy (TMA, Ormco) supplements the stainless steel and nickel-chromium-cobalt alloys traditionally used in orthodontic practice. The titanium wire has a lower modulus of elasticity (E) and a higher yield strength to modulus ratio (YS/E), which results in clinically desirable lower forces and ...

How Different Are Alternative Beta Strategies?

The Journal of Index Investing, 2016
In this article, the authors use a quantitative approach to compare different alternative beta strategies, based on statistical relationships among their returns. Using correlations, principal component analysis, regression factor models, and minimum spanning tree graphs, they identify and quantify statistical closeness of these portfolios. The results

Engineering Alternative .beta.-Turn Types in Staphylococcal Nuclease

Biochemistry, 1994
We have refined the crystal structures of three point mutants of staphylococcal nuclease designed to favor alternative beta-turn types. Single amino acid substitutions were made in a type VIa beta-turn (residues 115-118; Tyr-Lys-Pro-Asn) containing a cis Lys 116-Pro 117 peptide bond. The mutations result in two new backbone conformations, a type I beta-

Unlevering Equity Betas: Alternative Procedures

Business Valuation Review, 2006
Abstract This article presents an alternative methodology to unlever equity betas for the computation of the cost of capital. The “classic” Hamada formula assumes that the financial risk is borne by the shareholders of the company. The alternative formulas presented take a different option and assume that a portion of the risk should be ...

Alternative test conditions of beta - gamma monitors in beta radiation fields

Journal of Radiological Protection, 1997
An extrapolation chamber and the beta radiation secondary standard system of the Calibration Laboratory of S˜ ao Paulo, with sources of 90 Sr + 90 Y, were used to verify the influence of the beam flattening filter on the radiation field. Extrapolation curves, calibration and transmission factors were obtained with and without the presence of the beam ...

Quantifying Backtest Overfitting in Alternative Beta Strategies

SSRN Electronic Journal, 2016
The authors investigate the biases in the backtested performance of “alternative beta” strategies using a unique sample of 215 trading strategies developed and promoted by global investment banks. Their results lend support to the cautions in the recent literature regarding backtest overfitting and lack of robustness in trading strategy performance ...

Omega‐ and Beta‐Models of Alternative Set Theory

Mathematical Logic Quarterly, 1994
AbstractWe present the axioms of Alternative Set Theory (AST) in the language of second‐order arithmetic and study its ω‐ and β‐models. These are expansions of the form (M, M), M ⊆ P(M), of nonstandard models M of Peano arithmetic (PA) such that (M, M) ⊩ AST and ω ϵ M.
