The share of Starbucks Corp. (SBUX), rose in Tuesday's trading session, after the bankruptcy application of its Chinese competitor, Luckin Coffee Inc. Luckin Coffee, Starbucks's biggest competitor in China, is embroiled in a series of investigations into financial irregularities that led to layoffs, fines by US regulators and a drop in the stock price of more than 84% over the previous year. Starbucks expects to increase sales of its stores in China by almost 100% in the second quarter.
