Apple lost its status as the world's most valuable public company to Google's parent, Alphabet, in US trading as markets closer to home, in Europe, fell after a choppy session weighted down by disappointing earnings updates.

The iPhone maker's dip behind Google in trading on Thursday in New York was the second time this year such a move has occurred. A similar drop happened in early February after Alphabet reported fourth-quarter results that beat analysts' expectations. Apple took back the lead the next day.
