Traders looking for new market alternatives to Equity Index ETF’s ETN’s Unit Investment Trusts, should consider the advantages of smaller thinking. Smaller in capital outlay efficiencies but NOT smaller in opportunity.
The electronically traded E-mini S&P 500 has been more popular in recent years than its big brother, the S&P 500 futures contract. E-Mini S&P 500 margins (performance bonds) refer to the original deposit of money required to have in your account to enter into a contract. E-mini S&P 500 contracts are referred to as "E-mini" because they are E for electronically traded, rather than Pit Traded and just 1/5 of the scale of standard S&P 500 futures contracts. The many futures contracts that also offer an E-mini variant include:
- S&P MidCap (symbol EMD)
- NASDAQ 100 (symbol NQ, 100 largest NASDAQ companies)
- S&P Sector contracts including but not limited to the Healthcare sector, Utilities, Materials, Technology, Consumer Staples, ETC.
- Dow (symbol YM, traded on CBOT exchange)
- Russell 2000 (symbol RTY), small cap index
- Metals and commodities such as Copper, Gold, Silver, Corn, Wheat, Soybeans, Natural Gas, Crude Oil, Heating Oil and Unleaded Gasoline
- Forex rates versus the US Dollar such as Euro, British Pound, Swiss Franc, Japanese Yen, Australian Dollar, Canadian Dollar and Chinese Renminbi
E-Mini S&P 500 Margins~ Capital Efficiency
In the futures market, the margin, good faith deposit or performance bond refers to the initial deposit made in an account in order to enter into a futures contract. This margin is referred to as good faith as it is the money that is used to control each contract and is set aside from the rest of the funds in your account. The current E-Mini S&P margin is $13,200.00 to hold the position from day to day to day. Typically, the amount of money required is between 2% and 10% of the cash value of the contract and varies depending on the product and contract size. Preferential margins are a reality for many products during the daytime sessions that bring the good faith deposit required down to just $1320.00 per contract. Yes, during the day, you can control 1 contract of the E-Mini S&P if the current price is 3125.00 x $50.00 = $156,250.00 of equity for as little as $1320.00. The minimum overnight initial margin required is determined by the futures exchange. Such fixed initial margin levels are continually reassessed by the exchange, at times of strong market volatility, the initial margin criteria may be adjusted up or down..
When you offset your open position, the initial margin plus or minus any gains or losses that may arise will be added or subtracted to or from your cash balance. In other words, the value of your account changes, real-time, marked to the market, when the value of the asset in your account changes. This is called the Net Liquidating value of the account. Your Cash, plus or minus your open trade equity.
About The E-mini S&P 500 Futures
Introduced in 1998, the E-mini S&P 500 futures (ES symbol) on the Chicago Mercantile Exchange trades through the GLOBEX trade matching servers.It was the first vehicle of it’s size for both hedgers and speculators to take advantage of capital efficiencies in trading a broad market index
E-mini Capital Efficiency Compared To ETFs
E-mini offers greater capital efficiency compared to the use of the Exchange Traded Funds ( ETFs) on the stock exchange. This efficiency is one of the primary reasons why this future index has been so successful. For example, the full cash value of the E-mini is equal to the index price of the S&P 500 x $50. In other words, if the S&P E-mini were priced at 3125.00, the full cash value will be $156.250.00 per contract (3125.00 x $50.00). The intraday margin requirement is only $1320.00. For $132.000 you can control only $1320.00 of the SPY in your cash account, or $2640.00 worth of the SPY in a margin account that also charges you interest!. Futures margin has no interest expense.
