We consider option pricing when dynamic portfolios are discretely rebalanced. The portfolio adjustments only occur after ¯xed relative changes in the stock price. The stock price follows a marked point process and the market is incomplete. We first characterisethe equivalent martingale...

We study the dynamics of the spread between US corporate and Treasury bonds. We focus on Aaa and Baa corporate yield indices and estimate nonparametrically the dynamics of the spreads assuming that they follow a univariate diffusion process. Using technique developed for interest rate processes...

This paper offers an option pricing framework grounded in econometric microstructure modelling. We consider a model where stock price dynamics follow a pure jump process with constant jump size similar to a binomial setting with random time steps. Jump arrival times are described as an...

This paper presents results on the convergence for hedging strategies in the setting of incomplete financial markets. We examine the convergence of the so-called locally risk-minimizing strategy. It is proved that such a choice for the trading strategy, when perfect hedging of contingent claims...

This paper investigates the relationship between market microstructure and corporate governance in the Tunisian Stock Market. We examine in particular, the relationship between stock liquidity and institutional ownership by the type of institutions (e.g. banks, insurance companies, investment...

This paper deals with performance measurement of financial struc- tured products. For this purpose, we introduce the SharpeOmega ratio, based on put as downside risk measure. This allows to take account of the asymmetry of the return probability distribution. We provide gen- eral results about...

Portfolio insurance allows investors to recover at maturity a given percentage of their initial investment, whatever financial market evolu- tions. This portfolio insurance strategy limits downside risk in falling markets, while it allows potential benefits in rising markets. We analyze this...
