For two days in a row the CW for HK listed shares are in the top-10 volume. Since it is only 2 days of data, I am unable to make any analysis on the CWs. Will wait longer before deciding whether to trade or not. Anyhow, this is my analysis on the underlying shares.
PetroChina: In uptrend. Best bet at the moment.
ICBC: Still going down. Avoid!
ChinaMobile: Consolidation. Wait.
