New procedures for testing whether stock price processes are martingales
betting strategy efficient market hypothesis (EMH) game-theoretic probability sequential test
2010/11/1
We propose procedures for testing whether stock price processes are martingales based on limit order type betting strategies. We first show that the null hypothesis of martingale property of a stock p...
Differentiability of quadratic BSDEs generated by continuous martingales
Forward Backward Stochastic Differential Equation driven by continuous martingale quadratic growth Markov property BMO martingale
2010/11/1
In this paper we consider a class of BSDEs with drivers of quadratic growth, on a
stochastic basis generated by continuous local martingales. We first derive the Markov
property of a forward-backwar...
On the Martingale Property of Certain Local Martingales
Local martingales vs true martingales one-dimensional diffusions separating times
2010/11/1
The stochastic exponential Zt = exp{Mt − M0 − (1/2)hM,Mit} of a continuous local martingale M is itself a continuous local martingale. We give a necessary and sufficient condition for the ...
