Interactive Investor, for example, have confirmed that once the shares are moved over to HKEx they can still be held in the same ISA account and can still be traded online.
Seem to remember a couple of folks asking about interactive ?
ii confirmed that shares can still be held within ISA account and can also be traded online like normal after the move to HK ... they do need to complete a 'cross border' though and that can take several weeks (they say up to 6-8 but its not expected to be that long) during which time it can not be traded.
Thankfully only had beer money left in here ... but was in my nipper's jnr ISA so thanks Jim.
Jim Mellon was the main reason I didn't remain more invested here as I like the sector ... I will never again touch anything he is involved in with anyone's bargepole.
