Travel website Expedia Inc.‘s spin-off of TripAdvisor Inc. as a separately traded, independent company was complete Wednesday, with TripAdvisor shares set to start trading for the first time.

Expedia lost more than half their value and were trading at $27.37 before the opening bell, with investors believing TripAdvisor accounted for about half the market value of Expedia.
