Following its big rally up off of the 2020 market bottom, Booking Holdings (BKNG) spent most of 2021 stuck in a sideways trading range between $2,000 and $2,500 consolidating its gains. A November breakout turned to be false, but underlying support held through the ensuing correction, which occurred on falling volumes. Since December, accumulation has resumed with the shares climbing on increasing volumes. Yesterday, Booking broke out to a new all-time high above $2,700, signaling that the recent pause has ended and a new uptrend has commenced.
