What is the S&P 500?

The S&P 500, established on March 4, 1957, by Standard & Poor's (S&P), is a renowned stock index. S&P, formed in 1941 through the merger of Standard Statistics Company and Poor's Publishing, is a respected financial rating company. This index comprises 500 stocks traded on the New York Stock Exchange (NYSE) and represents a significant portion of the US stock market.

Approximately 80% of the total market capitalisation in the US stock market is accounted for by these 500 large-cap companies. This makes the S&P 500 an accurate reflection of the overall market situation.

Now, let's focus on Micro E-mini S&P 500 Index Futures.

What are Micro E-mini S&P 500 Index Futures?

Micro E-mini S&P 500 Index Futures are a scaled-down version of the traditional S&P 500 futures contract, similar to Mini Futures. Both are traded on the Chicago Mercantile Exchange (CME). These micro futures offer distinct advantages to investors, such as lower margin requirements, which translate to reduced capital needs for trading.

While a standard E-mini S&P 500 futures contract has a value of $50 per point, a micro contract is ten times smaller, with a value of $5 per point. The creation of S&P 500 micro futures, like mini futures, aims to expand access to index investment for a broader range of investors who may have been deterred by capital or risk constraints associated with the traditional S&P 500 futures.

How do Micro E-mini S&P 500 Index Futures work?

Micro E-mini S&P 500 Index Futures are traded on the Chicago Mercantile Exchange (CME), a part of the CME Group, with the S&P 500 stock index as their underlying asset.

Investors can speculate on the movements of the S&P 500, taking both bullish (expecting a rise) and bearish (anticipating a fall) positions. The process is straightforward:

  1. Choose your directional stance—upward or downward—based on your market outlook.
  2. If you foresee an upward trend, you buy. If you anticipate a decline, you sell (short).
  3. Determine the number of contracts to trade. More contracts amplify your potential gains or losses for each tick in your favour or against your position.

How much is a tick in the Micro E-mini S&P 500 Index Futures?

A “tick” is the smallest amount that a price can move up or down in the trading market. In the trading of S&P 500 index futures, the smallest price movement is 0.25 points. So if the index is at 3200, the next levels it can go to are 3200.25, 3200.50, 3200.75, and then 3201. This is true whether the index goes up or down.

So, in the S&P 500 futures, one tick means the price changed by 0.25 points. In simple terms, one full point equals four ticks because 1 divided by 0.25 equals 4. For the smaller Micro E-mini S&P 500 futures, each tick is worth $1.25. This is because one full point is worth $5, and a tick is a quarter of a point.

Here's an example to make it even clearer:

Let's say the S&P 500 index goes up by 10 points. Each tick (which is 0.25 points) changes the value of the Micro E-mini S&P 500 contract by $1.25. To find out the total change in the contract's value, you can do a simple math calculation:

  • 10 points increase in the index
  • 4 ticks make up one point
  • Each tick is worth $1.25

So, the contract's value would change by $50. The math looks like this: 10 points x 4 ticks per point x $1.25 per tick = $50.

At what time can it be traded?

The Micro E-mini S&P 500 futures are traded almost 24 hours a day, from Sunday evening to Friday evening in U.S. time. Specifically, trading starts at 6:00 p.m. Eastern Time (ET) on Sunday and ends at 5:00 p.m. ET on Friday. There is also a daily trading break from 5:00 p.m. to 6:00 p.m. ET.

For the UK, this means:

  • Trading starts: 11:00 p.m. UK time on Sunday
  • Trading ends: 10:00 p.m. UK time on Friday
  • Daily trading break: 10:00 p.m. to 11:00 p.m. UK time

Remember to double-check the time difference, especially during the periods when Daylight Saving Time starts or ends.

Expiration of the Micro E-mini S&P 500 Index Futures

Micro E-mini S&P 500 Index Futures usually expire on the third Friday of the contract month. The contract month is the month when the futures contract will end, and it is part of the contract's name. For example, if you are trading a “September” Micro E-mini S&P 500 futures contract, it will expire on the third Friday of September.

On the expiration day, trading of that specific contract usually stops in the early afternoon, U.S. time. After that, the contract is considered “settled,” which means it's closed and can't be traded anymore.

If you have an open position in a Micro E-mini S&P 500 futures contract that is expiring, you will need to either close the position before the expiration or it will be settled automatically based on specific rules. If you don't want your trading to stop, you can “roll over” your position to a contract with a later expiration date.

What is the main difference between the Micro and E-Mini futures?

The main difference between Micro and E-mini futures is their size. Specifically, Micro futures are much smaller than E-mini futures, which means they require less money to trade.

Here's a simple way to understand it:

  • An E-mini S&P 500 futures contract has a value of $50 per point.
  • A Micro E-mini S&P 500 futures contract is ten times smaller, with a value of $5 per point.

Because Micro futures are smaller, they require less money upfront, known as the “margin,” to start trading. This makes Micro futures more accessible for individual investors or those who are new to futures trading. It also means you're taking on less financial risk compared to trading the larger E-mini contracts.

Both Micro and E-mini futures are traded on the Chicago Mercantile Exchange (CME) and are ways to invest in the S&P 500 index. But, the smaller size of Micro futures makes them a more flexible option for a broader range of investors.

What is the best broker to invest in Micro E-mini S&P 500 Index Futures?

  4. Margin requirements: Check that the broker's margin requirements align with those specified by the CME Group Clearing House, without imposing higher amounts.
