Expedia jumped 25% and hit an all-time high after the online travel agent booked better-than-forecast first-quarter adjusted earnings and revenue. Expedia's report gave some lift to TripAdvisor, which also climbed 8.4%. "Earnings are consistently performing better than what had been, admittedly, very modest expectations," said Phil Orlando, chief equity strategist for Federated Investors. "The whisper thinking was that we would see negative year-over-year results for both revenue and earnings. The numbers are not blowouts, but we're getting single-digit growth for both the top and bottom lines." Not all reports were met with cheers. Procter & Gamble fell 4% after the consumer-goods company topped fiscal third-quarter earnings estimates but came up short of revenue forecasts. The company also provided a fourth-quarter outlook that was below projections. In U.S. economic news, first-quarter economic growth came in below consensus estimates.

The Stoxx Europe 600 rose 0.8% to notch its fifth advance in six sessions after Italy sold close to the maximum target of government bonds, erasing losses suffered after Standard & Poor's cut Spain's long-term sovereign-credit rating two notches. The index rose for the second Asian markets were mostly lower, as worries about Spain's downgrade offset additional easing moves by the Bank of Japan.
