HSI finished the day above its 200 Day MA, pushed on by the positive movement of $BABA and $PDD over the last few days.
$BABA and $JD report this week and they can influence the market here, coupled with PPI today and CPI tomorrow in the US.
Converting the 200 Day MA to support will be a strong sign that the pull back is complete and the next test will be getting back above the the 50 Day MA, confirming then the bullish trend.
