Too risky to play 1547 la, as its 最後交易日 is on 20 May 2008!! Of course if 883 rise, the gain will be so attractive, yet if 883 fall below 14.68, which can be very easily in these days of the volatile market, 1547 will become worthless.
883 rose quite a lot already, why not consider 857 and its warrants, more defensive and safer to speculate.
