PetroChina: A A-share of the "fixed Poseidon" or "Magic curse"?

Although the Monday Shanghai Composite Index still shows a narrow range of the trend of contraction, A slight increase of 14.75 points, and China's oil (601857.SH) 4.72% of the increase contributed 12.99 points of the increase, in other words, only one stock of oil has contributed to Prev Monday gain of 88%, in small and medium-sized stocks collectively appear a large drop in the case, PetroChina became a a-share "fixed Poseidon needle"　　is very obvious. But the impression that PetroChina has given investors since landing in the A-share market is not rosy. Since PetroChina in November 2007 A-share listing, a very strange phenomenon is that whenever the volume of oil rises, the performance of the market is often stagnant, and then the stock index may appear to adjust.　　For example, July 24, 2009, PetroChina soared 5.41%, the biggest increase of 7.82%, but Prev only Rose 1.33%, then on July 29, 2009, Prev fell 5%. And from the recent situation, November 11 this year, PetroChina Rose 7.69%, the plate was once on the touch of trading, but prev close but there was a sharp drop in trend, and to expand more than 400 points quickly fell. Even the sharp investors at that time based on the trading of oil and made a full clearance of the operation, thus successfully avoided the risk of this round of stock index callback.　　For a while, PetroChina's "magic spell" effect in the A-share market is known to all. Archimedes once said: "Give me a fulcrum, I can pry to move the earth." "And for the" full circulation "era of the A-share market, PetroChina is undoubtedly the best" fulcrum. "　　As the current a-share market's first weight shares, to PetroChina only 4 billion shares of the actual circulation plate can pry 161.5 billion shares full circulation, PetroChina has more than 40 times times the amplification effect, is its main choice of key reasons. As a result of PetroChina November 11 on the trading trend just happened in the "full circulation" after a few days, but also to increase the investors on the oil trend by some of the main agencies to manipulate the suspicion. Market participants believe that the main body by pulling high weights to attract the trend of the plate, in the stock index when the gradual layout of short positions of stock index futures, and then through the spread of bad manufacturing panic triggered the stock index fell to achieve the Profit trilogy.　　Because small and medium investors are limited by the amount of funds can not participate in stock index futures investment, may become "Man, I for fish" victim. Although there are many factors leading to the stock index bursts, the undeniable fact is that after the big curtain of stock index futures, China's securities market has entered the era of hedging and entered the era of stock index arbitrage which can make money short. This also means to like PetroChina such a super big market stock trend of the judge has become a compulsory course for stock investors, is far-reaching.　　So, will PetroChina's Monday rally reproduce the "magic spell" effect, or will it become the "fixed Poseidon" of the stock index? A private equity manager said that the "magic spell" effect of PetroChina was well known, and that it might be time for the reverse theory to work, and the operation of major fundsRoads are often contrary to the prevailing expectations of the market. And from the recent trend form of oil, there are gradually out of the bottom of the situation, coupled with PetroChina now is not high valuations, international crude oil prices and natural gas prices are rising, there should be some investment opportunities.
