美国股市的上扬,其实能够容纳的资金量并不是太大。真正的大容量,其实是两个市场。一个是金融衍生品市场,尤其是大宗商品交易市场。 ... Poo 发表于 2011-3-9 14:39 
这个,好像不对,commodity market应该没有股市大。
The global volume of commodities contracts traded on exchanges increased by a fifth in 2010, and a half since 2008, to around 2.5 billion million contracts. During the three years up to the end of 2010, global physical exports of commodities fell by 2%, while the outstanding value of OTC commodities derivatives declined by two-thirds as investors reduced risk following a five-fold increase in value outstanding in the previous three years. Trading on exchanges in China and India has gained in importance in recent years due to their emergence as significant commodities consumers and producers. China accounted for more than 60% of exchange-traded commodities in 2009, up on its 40% share in the previous year.
Commodity assets under management more than doubled between 2008 and 2010 to nearly $380bn. Inflows into the sector totalled over $60bn in 2010, the second highest year on record, down from the record $72bn allocated to commodities funds in the previous year. The bulk of funds went into precious metals and energy products. The growth in prices of many commodities in 2010 contributed to the increase in the value of commodities funds under management.
The size of the world stock market was estimated at about $36.6 trillion at the start of October 2008.[1] The total world derivatives market has been estimated at about $791 trillion face or nominal value,[2] 11 times the size of the entire world economy.[3] The value of the derivatives market, because it is stated in terms of notional values, cannot be directly compared to a stock or a fixed income security, which traditionally refers to an actual value. Moreover, the vast majority of derivatives 'cancel' each other out (i.e., a derivative 'bet' on an event occurring is offset by a comparable derivative 'bet' on the event not occurring). Many such relatively illiquid securities are valued as marked to model, rather than an actual market price.
