Now chinese government is trying to cool down the property market and stop people from borrowing to invest (and I think this is a good move), this will affect the banks share price a lot. So in the next 3 months the chance of 3988 get back to $4.1 is not high. But it has a very good chance to go back to $4.1 in 6 months, afterall 6% growth in half a year for the big bank share is more than reasonable when the country economy grew 10% last year. So buy or sell is depends on your cash flow.
If you want to buy more bank shares, I suggest you to buy 939 rather than 3988. Afterall 939 has P/E around 20, less than 3988 P/E 28. Besides diversify is better.
Don't buy it now, although there is a small gain today, but may be it's because people think that it's low then buy it. The government policy effect may not have finished, so it may still drops next week. You should buy it when the share price is steady (small gain/loss) for a few days.
