Alibaba stock slides 11% on revenue miss, lower guidance

$Alibaba(BABA.US)$ $ALIBABA GROUP HOLDING LTD(BABAF.US)$ Why this stock is so low does not make any logical sense: it's literally a behemoth who owns the market share of its line of business in China and despite Wall Street expectations - who by the way do not live in China to see what's happening there - the company has consistently outperform itself in terms of revenue and earnings of an average 30% year-over-year for the past 5 years. I mean there is no logical reason for this stock to go down, like literally. Fun fact: investors hear the company missed Wall Street revenue expectations by 5 % ( 1 billion difference) and boom - the stock goes 10 % down like it's some low company nobody ever heard of in their life. It just does not make sense. The company is doing very but Wall Street it's overshadowing its accomplishments with these "missed expectations".
