Accessing and managing credit risk has been a major area of interest and concern for both academics, practitioners and regulators, particularly in the afterwards of the recent 2008 financial crisis. Moreover, the effective management of credit risk is a challenge faced by any banking and...

The probability distribution of log-returns of financial time series, sampled at high frequency, is the basis for any further developments in quantitative finance. In this letter, we present experimental results based on a large set of time series on futures. Then, we show that the...

Factorial moments are convenient tools in particle physics to characterize the multiplicity distributions when phase-space resolution (Delta) becomes small. They include all correlations within the system of particles and represent integral characteristics of any correlation between these...

Factorial moments are convenient tools in nuclear physics to characterize the multiplicity distributions when phase-space resolution (Delta) becomes small. For uncorrelated particle production within Delta, Gaussian statistics holds and factorial moments Fq are equal to unity for all orders q....

The probability distribution of log-returns for financial time series, sampled at high frequency, is the basis for any further developments in quantitative finance. In this letter, we present experimental results based on a large set of time series on futures. We show that the t-distribution...

For the pedestrian observer, financial markets look completely random with erratic and uncontrollable behavior. To a large extend, this is correct. At first approximation the difference between real price changes and the random walk model is too small to be detected using traditional time series...

Valuation-based market timing demonstrates greater potential to improve risk-adjusted returns for conservative long-term investors than given credit by Fisher and Statman (2006). On a risk-adjusted basis, market-timing strategies provide comparable returns as a 100 percent stocks buy-and-hold...

Focusing on a “safe withdrawal rate” and then deriving a “wealth accumulation target” to achieve by the retirement date may not be the best way to approach retirement planning. Such a formulation isolates the working (accumulation) and retirement (decumulation) phases. When considered...
