I think u should sell 2866 and 1919, or at least one of them, because the prices for 1919/2866 have got up a lot, and the field (Ship transportation) have reach their peak and they will keep falling, this is why many big investors like Lee Ka Shing, JP Morgan had sold their 1919. The lowest price for 2866 within 58 weeks is $1.3 and the highest is $13. I think u should consider moving to another field.
390 is a very big national company, the price has just started to rise, if u hold it for long term, u will gain quite a lot and it is safer. U can consider buying it at around $8
Apart from that, I think u should keep 939 and 2628.
I hope my opinion can help u to form yr own decision.
