Facebook’s soaring valuation is spurring shareholders to slice and dice their stock, giving investors from Silicon Valley to Wall Street a chance to bet on the company.

EB Exchange Funds, based in San Francisco, as well as New York firms Felix Investments and GreenCrest Capital have opened Facebook funds for investors looking to get a piece of the social-networking company and its half-billion users.

By creating derivatives of the stock, the firms are helping Facebook keep its shareholder count below 500 so it doesn’t have to disclose results to the public.
