The initial public offerings of high-tech wunderkinder like Linked-In have Wall Street's bankers partying like it's 1999. But unless you're a well-connected customer, you probably won't be invited to partake in pre-launch share allocations.

You can still get a good taste of bubbly through IPO aftermarket funds. First Trust US IPO Index Fund (ticker: FPX), Guggenheim Spin-Off ETF Fund and Global IPO Plus Aftermarket Fund let you in on the action for as little as $35.
