A unit in the oil into the sea of "fixed" and "magic spell" needle effect playback

Although Monday stock index still render necking narrow shocks, slight rise 14.75 point, and PetroChina 4.72% increase on the contribution of 12.99 point increase, in other words, only in a stock's contribution to the Prev close up of 88% on Monday, in small and medium-sized spare units collective has sharply, as A unit in oil "fixed function" needle "are obvious.

However, since landing in petroleum A-share market to investors since the impression is not good. Since petroleum in November 2007, in A stock market, a very strange phenomenon that is marketplace, each of which the oil volume increases, the market's performance often stagnation, then stock index adjustment may occur. For example, 2009 24 July, oil prices for the whole day in 5.41% maximum increase, 7.82%, but rose only Prev close 1.33%, July 29, 2009, Prev close to 5% of the crash.

But judging by the recent developments, on 11 November of this year, the oil rose 7.69%, up on a touch more once daily limit, but it appears red high Hu Zhi fell sharply, and a decrease of more than 400 points quickly. Even have a keen investors at the basis of the increase in oil and made a full-line clearance operations, thereby successfully avoided the current risk of stock index callback. All of a sudden, the "spell in oil" effect in A stock market is best known.

Archimedes has said: "give me a fulcrum, I can move the Earth. "But for" the full circulation "times A unit in the oil market, is undoubtedly the best" pivot ". As A first stock market in oil quanzhonggu only 40 million shares of the actual flow that can move the 1615 million shares in circulation unit, in the more than 40 x magnification effect, is it the main preferred subject.

Due to petroleum 11 November on touch trend is the increase in "full circulation" after several days, it is added to the investors in the oil price manipulation by some of the main body of the suspect. Market participants believed that the main bodies through La high quanzhonggu attract follow the trend of disk, the index-high progressive layout index futures short position, and then through the spread of bad panic caused stock index fell to achieve profitability trilogy. Due to the small and medium-sized investors affected by the amount of available funds to participate in the stock index futures investment, may become a "human foibles, I fall prey to fish".

Although lead stock index straight straight down a number of factors, but the undeniable fact is that in the stock index futures pull back the curtains, the Chinese stock market has entered a hedge age, entered a short-or you can make money in the stock index arbitrage times. This also means that on such as the oil in a large stock movements Super judge has become a compulsory course for stock market investors, it is led by a hair and body. Then, in the oil Monday rose will reproduce the "spell" effect, or will it become a stock index "for Poseidon-pin"?

In my view, the "Petroleum" effect is a curse on it, given the fluidity of the tightening of the end of the year, the central bank interest rate increase, raise deposit reserve ratio of possibilities greatly enhanced, we should beware of petroleum in the main institutions use to empty A share index. 【 】
