Israel A. Englander & Co. is one of the largest independent derivatives brokerage firms in the United States. Englander has a dedicated group of traders participating in the index option pits on the CBOE, including all of the major indices, primarily: DJX , the Dow Jones Index, SPX , the S&P 500 Index, QQQ, Qubes and MNX, the mini-NASDAQ. Englander concentrates on SPX options that are based on the S&P 500 index, considered the most representative basket of stocks relative to the broader market.
