Wendel slumps as weak dollar in private portfolio weighs on NAV

** Shares in Wendel MF fall close to 9%, hit by lower H1 net asset value

** Wendel reports 4% drop in H1 NAV at 7.30 billion euros ($8.35 billion), from 7..61 billion euros a year ago

** Degroof Petercam says NAV is 7% below its estimate of 180.1 euros per share as it "underestimated the FX impact from the dollar in the private portfolio"

** The broker adds the results were hit by mixed results in private assets, with Crisis Prevention Institute and Scalian & Stahl posting weak results

** Shares in Wendel are on track for their worst day since June 22, if losses hold
