Shares of Expedia are under pressure with the formation of a negative Stair-Step pattern, visible through negative spikes 1, 2 and 3. Negative Stair-Step patterns represent heavy institutional selling over an extended period. Travel related stocks, in general, have suffered over fear that Amazon would enter the hotel and hospitality booking industry and a data breach at Expedia’s Orbitz division of almost one million users has driven institutonal investors away from the stock.
