Dresdner Kleinwort Wasserstein is preparing to offer options on alternative investments within the next couple of months. Robin Farrell, head of the alternative investments group in London, said demand for these products has picked up recently because there is a greater impetus to invest in hedge funds in a bear market. The group already writes guaranteed notes on mutual funds and Farrell said it is the next step to offer the same products on baskets of hedge funds. Options on hedge funds are harder to structure than mutual funds because the underlying is less liquid.
