Ecommerce giant, JD.com $JD has been bullish. However, this bullish trend has become choppy in the second half of 2017 and into 2018, but nonetheless bullish.After making a new high just above $51 a share, JD retreated. However, the fact that it has been holding above the 200-day simple moving average suggests JD is still bullish.JD Daily Chart(click to enlarge)Key Support:- The 200-day SMA is indeed a key support. But we should expand the expectation of support to the $40-$42 area.- A break below $40 would be needed to convince the market is no longer bullish.- In this non-bullish outlook, there is a short-term bearish outlook towards the $36-$36.70 area.- The RSI is also indicative of a bullish market as it tries to hold above 40.Key Resistance:- Here's the thing, the overall picture is still bullish, but price action can be developing in the short-term that might shift the overall picture.- For example, if there is a rally, and price can not break above $46 and instead retreats back towards $40-$42, I would lose confidence in this support.Basically, JD is at the crossroad between maintaining a bullish market, or retreating into a period of consolidation. The chart so far supports the former, but certain price action coming up could suggest the latter.
