Mean-Variance Hedging Under Partial Information

Abstract: We consider the mean-variance hedging problem under partial Information. The underlying asset price process follows a continuous semimartingale and strategies have to be constructed when only part of the information in the market is available. We show that the initial mean variance hedging problem is equivalent to a new mean variance hedging problem with an additional correction term, which is formulated in terms of observable processes. We prove that the value process of the reduced problem is a square trinom… Show more

“…Similarly, if we assume σ t and ρ t are observable, we immediately have that ψ F t is F η -adapted and θ t = θ t and, thus, μ t is F η -adapted. Conversely, since all conditions of Theorem 2.1 are satisfied, the process V t is the unique bounded strictly positive solution of Equation (21). Note that θ t = θ t and ρ t = ρ t .…”

“…The technique is extended for a partial information setup by Mania et.al. (2008) [15], for utility maximization by Mania & Santacroce (2010) [16], and for MVH problem with general semimartingales by Jeanblanc et.al. (2012) [7].…”

“…under the hypothesis F S ⊆ G. We include the case when the flow of observable events G does not necessarily contain all information on prices of the underlying asset, i.e., when S, as well as R, is not a G-semimartingale in general. Such an approach, in the context of exponential and mean variance hedging, was considered respectively in [14] and [16] (see also [23,4,20] for the mean variance hedging problem under partial information). We show that the initial problem (1) is equivalent to another maximization problem written in terms of the filtered terminal wealth.…”
