Asian option pricing under sub-fractional vasicek model

open access: yesQuantitative Finance and Economics, 2023
This paper investigates the pricing formula for geometric Asian options where the underlying asset is driven by the sub-fractional Brownian motion with interest rate satisfying the sub-fractional Vasicek model.

Research on Systemic Risk of the Turkish Banking Industry Based on a Systemic Risk Measurement Framework of the Fractional Brownian Motion

open access: yesDiscrete Dynamics in Nature and Society, 2021
Since the 2008 financial crisis, it is an important issue to assess the systemic risk of banks, but there is a lack of research on the assessment of the systemic risk of Turkey’s financial system. In addition, geometric Brownian motion is used in most of

Long-Range Dependence in Financial Markets: a Moving Average Cluster Entropy Approach [PDF]

open access: yes, 2020
A perspective is taken on the intangible complexity of economic and social systems by investigating the underlying dynamical processes that produce, store and transmit information in financial time series in terms of the \textit{moving average cluster ...

Topological Subordination in Quantum Mechanics

open access: yesFractal and Fractional, 2023
An example of non-Markovian quantum dynamics is considered in the framework of a geometrical (topological) subordination approach. The specific property of the model is that it coincides exactly with the fractional diffusion equation, which describes the

The valuation of barrier options under a threshold rough Heston model

open access: yesJournal of Management Science and Engineering, 2023
In this paper, we propose a novel model for pricing double barrier options, where the asset price is modeled as a threshold geometric Brownian motion time changed by an integrated activity rate process, which is driven by the convolution of a fractional ...

Large deviations for rough paths of the fractional Brownian motion [PDF]

open access: yes, 2004
Starting from the construction of a geometric rough path associated with a fractional Brownian motion with Hurst parameter $H\in]{1/4}, {1/2}[$ given by Coutin and Qian (2002), we prove a large deviation principle in the space of geometric rough paths ...

Surveying the best volatility measurements to forecast stock market [PDF]

open access: yes, 2017
This paper investigates methods to forecast future adjusted price of S&P 500 by using geometric Brownian motion (GBM) and geometric fractional Brownian motion (GFBM) for better investment decision.

Large Deviation Principle for Enhanced Gaussian Processes [PDF]

open access: yes, 2006
We study large deviation principles for Gaussian processes lifted to the free nilpotent group of step N. We apply this to a large class of Gaussian processes lifted to geometric rough paths.

Fractional Brownian motion with a reflecting wall [PDF]

open access: yes, 2018
Fractional Brownian motion, a stochastic process with long-time correlations between its increments, is a prototypical model for anomalous diffusion.
