Lagged accuracy in credit-risk measures
(Elsevier, 2022) Abinzano Guillén, María Isabel; González Urteaga, Ana; Muga Caperos, Luis Fernando; Sánchez Alegría, Santiago; Institute for Advanced Research in Business and Economics - INARBE
This paper analyzes the magnitude (accuracy) and length (time) of the lag in the incorporation of new information in different measures of credit risk. The results, for US firms, show a lag for Altman’s Z accounting measure and credit rating. In contrast, market-based credit-risk measures such as CDSs and the Black-Scholes-Merton model show no lag. This paper also analyzes the determinants of the lags found showing the importance of the informativeness of CDSs in reducing the lag for all types of default events, and a negative relationship between accounting manipulation and the lag of Altman’s Z for severe default events.

This paper aims to describe a teaching-learning experience based on ProjectBased Learning (PBL). This experience is part of an educational innovation project devoted to transforming finance classes in various facets of financial advice. Specifically, the article focuses on the transformation process of a subject that studies financial markets and the assets traded in them. Based on this experience, the classroom becomes a financial consulting firm that advises investors on how to invest their capital. The results show us a remarkable active dedication of the students to the course, improved knowledge, and marks. In addition, the development of skills and values such as teamwork, autonomy, solidarity, equality, and professional skills are elements that encourage us to continue along this line.

Coasimetría idiosincrática y riesgo de insolvencia en el mercado de valores español
(AECA, 2014) González Urteaga, Ana; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
En el presente trabajo se analiza la relación entre el riesgo asimétrico, aproximado por las medidas de coasimetría y coasimetría idiosincrática, y el riesgo de insolvencia en el mercado de valores español. Se ha encontrado que aquellos títulos con mayor riesgo asimétrico proporcionan mayores rentabilidades durante el periodo considerado, en especial aquellos con valores positivos de la medida de coasimetría idiosincrática. Sin embargo, ni los factores de riesgo construidos en base a esta medida, ni el factor de riesgo de coasimetría proporcionan capacidad explicativa a las rentabilidades diferenciales de las carteras convencionales formadas por riesgo de insolvencia, siendo principalmente el factor tamaño (SMB) el que aporta explicación a dichas rentabilidades, tanto en periodos expansivos como durante el periodo de crisis financiera. Los factores de riesgo asimétrico únicamente presentan capacidad explicativa en el caso de carteras con riesgo de insolvencia más extremo y durante el periodo de crisis financiera internacional.

Momentum and default risk. Some results using the jump component
(Elsevier, 2015) González Urteaga, Ana; Muga Caperos, Luis Fernando; Santamaría Aquilué, Rafael; Gestión de Empresas; Enpresen Kudeaketa
In this paper we separate the total stock return into its continuous and jump component to test whether stock return predictability should be attributed to omitted risk factors or behavioral finance theories. We extend results from the US market to the Spanish stock market, which, despite being a developed market, presents several differences in terms of stock characteristics, financial system, investor typology and cultural dimensions. The results show that the jump component has significant explanatory power for the premium of three characteristics (size, book-to-market and illiquidity), which is at odds with risk-based explanations. Using the same testing strategy, we try to shed some light on an important controversy concerning the relationship between default risk and momentum. The results suggest that default risk is not the source of momentum returns.

Performance of default-risk measures: the sample matters

This paper examines the predictive power of the main default-risk measures used by both academics and practitioners, including accounting measures, market-price-based measures and the credit rating. Given that some measures are unavailable for some firm types, pair wise comparisons are made between the various measures, using same-size samples in every case. The results show the superiority of market-based measures, although their accuracy depends on the prediction horizon and the type of default events considered. Furthermore, examination shows that the effect of within-sample firm characteristics varies across measures. The overall finding is of poorer goodness of fit for accurate default prediction in samples characterised by high book-to-market ratios and/or high asset intangibility, both of which suggest pricing difficulty. In the case of large-firm samples, goodness of fit is in general negatively related to size, possibly because of the 'too-big-to-fail' effect.
