We re-examine performance persistence amongst UK mutual funds. Specifically, we investigate performance persistence among small portfolios of past high-performing funds. In contrast to the more common analysis of decile portfolios of funds, we focus on persistence in the more extreme positive...

This presentation introduces the rough path-dependent volatility model (RPDVM). After defining the model and its different components, the presentation focuses on various specifications of the RPDVM that already exist in the literature. Finally, a Markovian approximation of the model is presented

We re-examine US mutual fund performance persistence. We investigate persistence (i) using both “academic” factor models and “practitioner” index models, (ii) using decile-size recursive portfolios and also portfolios formed from smaller numbers of funds, (iii) using nonparametric...

The credit crisis and the following sovereign debt crisis during 2007 and 2012 led to an increasing volatility of European corporate bond credit spreads. European investment grade credit spreads rose in 2007 and 2008 from 50 BP to over 350 BP. In the years after the credit spreads declined to...

The measurement of credit quality is at the heart of the models designed to assess the reserves and capital needed to support the risks of both individual credits and portfolios of credit instruments. A popular specification for credit- rating transitions is the simple, time-homogeneous Markov...

This paper documents that the size effect (Banz, 1981) and the contrarian effect (DeBondt and Thaler, 1985) can be explained by a measurement error in beta. This measurement error results from a change in financial leverage during the beta estimation window. Based on simulations of asset...

Implicit in industry standard option pricing models is the expectation that roughly 25% of stocks with 60% consistent volatility will septuple within 10 years, an extraordinary rate of appreciation. The exceptionally high equilibrium anticipated returns for an improbably large percentage of high...

Pushing models to extremes can expose output biases that stem from underlying assumptions. In the case of industry standard option valuation models, long term, high volatility securities provide a stress test vehicle. For instance, in evaluating a stock with 60% volatility, industry standard...
