Hedging under arbitrageAdd to your list(s) Download to your calendar using vCal
If you have a question about this talk, please contact Berestycki. Explicit formulas for optimal trading strategies in terms of minimal required initial capital are derived to replicate a given terminal wealth in a continuous-time Markovian context. To achieve this goal this talk does not assume the existence of an equivalent local martingale measure. Instead a new measure is constructed under which the dynamics of the stock price processes simplify. It is shown that delta hedging does not depend on the ``no free lunch with vanishing risk’’ assumption. However, in the case of arbitrage the problem of finding an optimal strategy is directly linked to the non-uniqueness of the partial differential equation corresponding to the Black-Scholes equation. The recently often discussed phenomenon of ``bubbles’’ is a special case of the setting in this talk. This talk is part of the Probability series. This talk is included in these lists:
