Yes, of course, especially for newcomers that want to make short term profit, as good news may have already reflected . Also bear in mind that a large percentage of 939 (over 90%) is held by foreign corporate investors, their investment decisions will have decisive effects in the future of 939.
I guess the price of 939 will make significant progress like 3328 if her performance is better than expected and stock evaluation corporations lift 939 from previous standings. On other hand, those that buy in below HK$3 can make a good profit in short term within HK$3.4/3.5.
Anyway, 939 may become another 005 in future but offering higher appreciation in stock price. However, it may not generate interest return to stockholders as generous as the latter. For example, another bank from China, 3328, have not offered any interest return to stockholders in previous performance announcements.
