I am not shorting BABA; I am just making an observation of where I think it will go next. I haven't checked the microeconomic-fundamentals of the company. Observing price only is called gambling, not investing. There are some professional gamblers out there; speculators using "price action" or technical analysis alone, and these are gamblers/speculators.
Capturing the swings of the stock market & currency market. It's a dirty job and equity/currency traders must do it.
