As you probably know, I have held both AABA and SINA through all the market turmoil. This has been because they are real companies that were cut in half, but it has been despite  no actionable improvements in their charts.
Another Chinese stock that got halved that does have an actionable looking technical improvement is TCEHY as it is threatening to break through the neckline resistance of an Inverted H&S on the daily chart. The down-sloping SMA 200 stands as resistance to this happy scenario. But the pattern measures to 52 (+/-) if the breakout succeeds.
The weekly chart shows that a harsh downtrend was broken in Q4 2018.
A stop loss to a bullish scenario is per individual risk tolerance. That ranges from a failure of the neckline to a drop below the SMA 50 at 39.
A reminder that chart based NFTRH+ updates are technical trade setup ideas, which may not be revisited as the buy, sell, stop parameters are already noted. They are meant as a starting point for your further research if interested. I will not personally buy every item highlighted and will sometimes sell (ref. Trade Log) any item that I do buy below target (assuming I’ve not stopped out or sold for some other reason) as I often do. Also please be aware that I am not a fundamental stock analyst. Due diligence is your responsibility.
