and, 5:3 end 2009,

however, it should be noticed that long term ps price likely will go down, if not already, due to rapidly expanding industry capacity,

in fact, last weeks Businessweek reported some funds have started short position in WFR, (as crazy as it sounds)

so imho there is a time window for long, and potentially very profitable if LDK keeps delivering 100% growth numbers, but this window may be much more narrow than most others,

all good luck,
