再扫盲：16妈最近做的ES是什么东西？

最近16妈常常讲到她在trade ES，楼下有人问ES是什么。其实这里的ES就是所谓的E-mini S&P500 Futures。我觉得用中文讲不太清楚，就把网上查到的讲得比较清楚的信息（英文）摘抄在下面，希望帮助你了解。

An "e-mini" is an electronically traded futures contract that represents a portion of a standard futures contract. As futures contracts, the e-minis represent an agreement to buy or sell the cash value of the underlying index at a specified future date. The contracts are sized at a certain value multiplied by the futures price; this value depends on the particular e-mini. The e-mini S&P 500, for example, has a contract size of $50 times the e-mini S&P 500 futures price. If the value of the e-mini S&P 500 is $2,000, the value of the contract is $100,000 ($50 x $2000). The value of the contract changes as the price of the futures moves. 

The most popular e-mini stock index futures contracts include the following:

• E-mini S&P 500 (ES)
  
• E-mini NASDAQ-100 (NQ)
  
• E-mini Dow (YM)
  
• E-mini Russell 2000 (TF)

其中ES，NQ和YM都在CME Globex平台交易，下面有它们的specs。而TF（又叫RJ）在ICE交易，它的specs下面也有。大部分futures按季度结算，下边table里HMUZ对应的月份（months）是3，6，9，12。GD和VI是按月结算。
