E-mini S&P (ES)

The e-mini S&P (ES) is a derivative contract established in 1997. It has become a very popular and highly liquid trading instrument.

This contract trades electronically on the Globex platform through the CME.

The contract size is one fifth that of a standard S&P contract at $50 per point, with a tick size of one quarter point ($12.50.)

Contract months for the ES are March (H), June (M), September (U), and December (Z). The last trading day is the third Friday of the expiry month, with trading possible until 8.30a.m. on that day.

Contract rollover occurs on the Thursday a week before the expiration Friday – for the e-minis, this is the second Thursday of March, June, September and December. (If the Rollover month starts on a Friday, the Rollover is the first Thursday of the month.) The next contract becomes the “lead contract” or the “front month”. Even though the previous contract continues to trade until expiration, the majority of trading moves to the next contract.

Trading can take place from Monday to Friday from 5:00 p.m. on the previous day until 4:15 p.m., with a trading halt from 3:15 p.m. – 3:30 p.m.

Most brokers require a margin of $500 per contract for day-trading, and $3,500+ for holding overnight.


Many of the e-mini futures contracts trade under high volume; the ES is the highest of these, with over 2.2 million contracts traded on average per day, providing excellent liquidity.

Total volume for the June 2014 contract on April 7th. 2014 was 2,177,873. (Source: CME.)

Very high correlation between S&P and the DAX index:


High correlation between S&P and GBP:-


Lower correlation between the S&P and the EURO:


Lower correlation between the S&P and the 10 year T-Note:


As the S&P has such a broad coverage of equities, it tends to be highly correlated with many markets.

Of the markets viewed, the 10 year T-Note is a possible alternative to trade, being less correlated than others.


The e-mini S&P is one of the highest volume instruments and has excellent liquidity, makig it very suitable for day-trading.

It is most active during the U.S. trading session, and tends to experience intra-day reversal periods, such as 2.30p.m. CST and 7.00p.m. CST. The latter time often sees an influx of bond traders into the market.

The S&P “backs and fills”, so once a trend s apparent, there are opportunities to enter on pull-backs in price.

Alternative markets to trade with lower correlations are the 10 year T-note and possibly the Euro currency.
