The Chicago Board Options Exchange (), located at 400 South LaSalle Street in Chicago, is the largest U.S. options exchange with annual trading volume that hovered around one billion contracts at the end of 2007.〔(【引用サイトリンク】title=Choose CBOE )〕 CBOE offers options on over 2,200 companies, 22 stock indices, and 140 exchange-traded funds (ETFs). The Chicago Board of Trade established the Chicago Board Options Exchange in 1973. The first exchange to list standardized, exchange-traded stock options began its first day of trading on April 26, 1973, in a celebration of the 125th birthday of the Chicago Board of Trade.〔(【引用サイトリンク】title=History )〕 The CBOE is regulated by the Securities and Exchange Commission. ==Operations== CBOE's options contracts are cleared by the Options Clearing Corporation (OCC). As of approximately April 11, 2007, the ''Wall Street Journal'' estimates that globally the market capitalization of the derivatives markets (futures, options, swaps, etc.) exceeds 450 trillion dollars (while US stock exchanges have approximately 30 trillion and the rest of the worlds stock exchanges total to about another 20 trillion, to a total of about 50 trillion—while the global fixed income markets total to roughly 65 trillion). In 2004, CBOE opened trading on the CBOE Futures Exchange for volatility and variance contracts and in 2007 launched a Reg NMS-compliant stock exchange called the CBOE Stock Exchange (CBSX) to compete with the NYSE, Nasdaq, and other regional exchanges. The CBOE Stock Exchange ceased its trading operations on April 30, 2014.〔http://www.cbsx.com/publish/RegCir/RG14-069.pdf〕〔http://www.chicagobusiness.com/article/20140221/NEWS01/140229959/cboe-to-exit-stock-exchange-business〕 Trading at CBOE is carried out by way of the exchange's Hybrid system, which enables customers to trade – either electronically or through open outcry. About 95 percent of CBOE orders are traded electronically, which equates to between 50 and 60 percent of the exchange's total business. The remaining transactions, traded via open outcry, typically are large or complex institutional orders that use the skills of floor brokers to "work the order" to gain potential price improvement. On March 11, 2010 CBOE filed paperwork to launch an initial public offering〔(【引用サイトリンク】title=CBOE files paperwork for IPO )〕 and began trading on the NASDAQ stock exchange on June 15, 2010. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chicago Board Options Exchange」の詳細全文を読む スポンサード リンク
