Alibaba $BABA shares are struggling in 2018 amidst the China-US trade war. This week it fell through another key level that was around $150 share price. How low will it go?BABA Weekly Chart(click to enlarge)Breaking Key Support:- Note that the 38.2% retracement level was just above $150 and was providing support, but is now broken. - Furthermore, there was a support/resistance pivot around $148.50, and that broke too.Fibonacci Retracement Levels:- Sometimes traders like to use Fibonacci Retracement Levels to guide their entries. I think the 50% and 61.% retracement levels will be sticky. Otherwise, we might see price find anchor back up between these levels. - 50% retracement is around $135.- 61.8% retracement is around $116. - Indeed, I think $135-$140 is the first key support area. I think the market is still pricing in the trade war among other fundamentals, but I don't think there will be more than another 10% dip. - But if there is another escalation of the trade war that has not been priced in yet, the momentum might drag BABA down to the $116-$120 area, Personally, I have been rotating out of the market into cash, although some trades have been triggered this week due to the dips. I think it is prudent to get dry powder ready for the potential market correction coming up. As a long-term investment play, I am planning to start adding around $140 all the way down to $115.
