This implies in practice dis ˆ that when St (p, k, τn ) is superior to cn,t , we cannot conclude that the dynamics display jumps.

23) where Δxt represents the cash variation related to all the management operations on the portfolio: subscriptions and lapses, revaluations of assets in the case of swaps, taxes, brokerage, management, and financial fees.
