TripAdvisor tumbled 9.2 percent, the biggest drop in the S&P 500, after CEO Steve Kaufer said summer has been ‘‘bumpier’’ than forecast and traffic on TripAdvisor’s travel website is ‘‘not as strong’’ as anticipated. TripAdvisor recently rolled out a new method of directing customers to booking partners like Expedia. Kaufer said fewer click-throughs to third-party sites have yet to be offset by higher prices TripAdvisor can charge for clicks that have a greater chance of converting into a booking. He expects improvement by the end of the year.
