After the modest rebound in early December, PTA (purified Terephthalic acid) main futures contract deal dropped again to Brin in the channel near the rail line, but weakened fell low kinetic energy.　　The author believes that due to lack of guidance and good than the bad factors of factor price shocks in the short term, its break up or down in space are not great. Profit-driven,PTA fall kinetic energy is limited. Since the second quarter, PTA production profits of enterprises gradually compressed, until the end of November, PTA enterprises are nearly cost line. Collapse of profits force companies to take reduction measures of value-insured, device maintenance scheduling arrangements more corporate production load to about 83%. PTA production expected, helped by lower in advance before entering the FestivalPicking phase, and drive futures rebounded slightly in early December, out of the market. However, PTA production profits of enterprises in the process did not get promoted. This is because, on the one hand, its own supplies tight, upstream PX (PX) easier to rise downstream market, prices in the past two weeks have steadily moved up the center of gravity, making profits hard left in PTA process;The other hand, because pet market was previously on the cost lines in the lower bottom run, enterprises in the case of loss of profits share up the will is not strong, made from the Terminal stock market profits in pet link interception of more. Main capital stocks (twelve-twenty thirds) unit fled to cut meat must regret having sudden boom is not likely in a move investors Gospel: hold stockSaved! As of December 16 the week on the spot price estimates, PTA average production profits shrunk to near 160 Yuan/ton swtor leveling service, PX average production margin to 150 USD/ton in the upper reaches near the downstream of pet staple fiber production enterprises, polyester filament production also have a more significant increase of profits. As the profit upgrade, pass on the downstream costs of pet marketCapacity also increased.　　In this context, profits from both ends to the PTA process flow of the pressure will continue to increase and will drive PTA prices stabilised or restorative rebounded slightly. Decrease in the lower atmosphere, it is difficult to form active pull up. Lower stock market is rebounding slightly in early December to promote PTA main drivers. However, as the water Terminal textile raw material inventoryIncrease enterprise purchase State of mind is moving towards cautious, chasing rising stocks were not enthusiastic, climate of market turnover decline, periodic stock market close. Because of the approaching lunar new year, subsequent load, there is a large textile factory loom improved enterprise inventory to consumption and demand the maintenance, it is difficult to pose to upstream initiative pulled up. Decrease in the lower atmosphere, the PTA Bull sentimentSystem, and limit the PTA up space.　　Moreover, taking into account the lower now in low season, final demand is relatively weak, downstream is likely to again be experienced stock downturn, which may be holding PTA remain vulnerable. Macro market continued disturbances. European debt crisis is not yet clear and effective solutions that will increase the market on fears of economic slowdown Swtor power leveling, which in turnPressured the commodities market; Europe, recent discussions on Iran to take further sanctions, Iran crude oil prices will directly affect the progress of the situation, and can turn around the trend; the situation in North Korea after Kim Jong-Il's death is unclear, geo-political factors have increased market uncertainty; domestic regulation towards "growth" of expected enhancements, with the falling stock market, politicsGo loose policies will have a clearer signal, it remains to be seen.　　Macroscopic factors intertwined, but lack strong initiative factors, their impact on PTA futures are still dominated by increased volatility. The above aspects, I believe that PTA is profit-driven to fall is unlikely in the short term, there is a modest rebound momentum. However, due to lack of more factors, combined with the nextStroll about weaker, dragged down space above it is also more limited, are expected by early afternoon in macro-shocks under surface disturbance, 1205 contracts shock the Centre of gravity above the basic at $ 8,200.
