So what
While Baozun's fresh earnings report is probably playing some role in today's sell-off, it's likely that fears trade talks between China and the U.S. will fail to yield a positive outcome have investors concerned and selling.

Now what
There are some legitimate reasons for investors to be cautious. China's economic growth is indeed slowing; if projections that it will grow less than 6.5% in 2019 prove true, that would be the country's weakest GDP growth in nearly three decades. Moreover, a protracted trade war with the U.S. would almost certainly be bad for both countries.
But stock investors have to be willing -- and able -- to ride out short-term volatility if a company's long-term thesis is sound. And Baozun is absolutely a stock worth buying and owning for the long term, even as China's economic growth slows and risks of trade disagreements with the U.S. continue.
As Baozun CEO Vincent Qiu reminded investors on the earnings call, even if China's economic growth does slow, the country's burgeoning middle class continues to expand at a high rate, and retail is quickly shifting online there. Those tailwinds will likely persist for years to come, and Baozun is investing to be a major participant -- and beneficiary -- of that shift.
