Self-Regulatory Organization
Although United States commodity exchanges ultimately function under the auspices of the Commodity Futures Trading Commission, daily operations are regulated from within the organization. Trade, market, and financial surveillance are performed to ensure the utmost integrity of futures trading.

Sellers' Market
A condition of the market in which there is a scarcity of goods available and hence sellers can obtain better conditions of sale or higher prices. Opposite of buyer’s market.

Selling Hedge (Or Short Hedge)
Selling futures contracts to protect against possible decreased prices of commodities. Also see hedging.

Serial Expiration
Options on the same underlying futures contract which expire in more than one month. NYMEX Division platinum options have serial expiration.

Series
All options of the same class which share a common strike price.

Settlement or Settling Price
The price established by the Exchange settlement committee at the close of each trading session as the official price to be used by the clearinghouse in determining net gains or losses, margin requirements, and the next day’s price limits. The term “settlement price” is often used as an approximate equivalent to the term “closing price.” The close in futures trading refers to a brief period at the end of the day, during which transactions frequently take place quickly and at a range of prices immediately before the bell. Therefore, there frequently is no single closing price, but a range of prices. In months with significant activity, the settlement price is derived by calculating the weighted average of the prices at which trades were conducted during that period.

Short
1) The market position of a futures contract seller whose sale obligates him to deliver the commodity unless he liquidates his contract by an offsetting purchase.
2) A trader whose net position in the futures market shows an excess of open sales over open purchases.
3) The holder of a short position.
4) In the options market, the position of the seller of a call or a put option. The short in the options market is obliged to take a futures position if he is assigned for exercise. Opposite of long.

Short Selling
Selling a contract with the idea of delivering or of buying to offset it at a later date.

Short-The-Basis
A person or firm that has a commitment to sell in the cash or spot markets and hedges through the purchase of futures is said to be short-the-basis.

Sour Or Sweet Crude
Industry terms which denote the relative degree of a given crude oil’s sulfur content. Sour crude refers to those crudes with a comparatively high sulfur content, 0.5% by weight and above; sweet refers to those crudes with sulfur content of less than 0.5%.

Specifications
1) Contract terms specified by the Exchange.
2) Term referring to the properties of a given crude oil or refined petroleum product, which are "specified" since they often vary widely even within the same grade of product. In the normal process of negotiation, the seller will guarantee the buyer that the product or crude to be sold will meet certain specified limits. Generally, the major properties of oil that are guaranteed are API gravity, sulfur, pour point, viscosity, and BS&W.

Specific Gravity
The ratio of the density of a substance at 60 degrees Fahrenheit to the density of water at the same temperature.

Speculator
A trader who hopes to profit from the specific directional price move of a futures or options contract, or commodity.

Spot
Term which describes one-time open market cash transaction, where a commodity is purchased "on the spot" at current market rates. Spot transactions are in contrast to term sales, which specify a steady supply of product over a period of time.

Spot Market
A market of immediate delivery of product and immediate payment.

Spot Month
The futures contract closest to maturity. The nearby delivery month.

Spread (Futures)
The simultaneous purchase and sale of futures contracts for different months, different commodities, or different grades of the same commodity.

Spread (Options)
The purchase and sale of options which vary in terms of type (call or put), strike prices, expiration dates, or both. May also refer to an options contract purchase (sale) and the simultaneous sale (purchase) of a futures contract for the same underlying commodity.

Stock-Type Settlement
A settlement procedure in which the purchase of a contract requires immediate and full payment by the buyer to the seller. In stock-type settlement, the actual cash profit or loss from a trade is not realized until the position is liquidated. Exchange options have this type of settlement
procedure, which differs from that in the futures market where gains and losses are realized on a daily basis.

Stop Order
An order that becomes a market order when the market reaches the elected price of the stop order. See market order.

Stop Limit Order
An order that goes into force as soon as there is a trade at the specified stop price. The order, however, can only be filled at the limit price or better. The stop price and the limit price can be the same or different. The stop price is the price level specified in the order.

Stop-Loss
A resting order designed to close out a losing position when the price reaches a level specified in the order. It becomes an at-the-market order when the "stop" price is reached. Individuals also use stops to enter the market when the prices reach a specified level.

Straddle (Futures)
Also known as a spread, the purchase of one
futures month against the sale of another futures month
of the same commodity. A straddle trade is based on a
price relationship between the two months.

Straddle (Options)
T
he purchase or sale of both a put and a call having the same strike price and expiration date. The buyer of a straddle benefits from increased volatility, and the seller benefits from decreased volatility.

Strangle
An options position consisting of the purchase or sale of put and call options having the same expiration but different strike prices.

Strike Price
The price at which the underlying futures contract is bought or sold in the event an options contract is exercised. Also called an exercise price.

Strip
The simultaneous purchase (or sale) of an equal number of futures positions in consecutive months. The average of the prices for the futures contracts bought (or sold) is the price level of the hedge. A six-month strip, for example, consists of an equal number of futures contracts for each of six consecutive contract months. Also known as a calendar strip.

Sulfur
An element that is present in some oil, gas, and coal as an impurity in the form of its various compounds.

Support
In technical analysis, a price area where new buying is likely to come in and stem any decline.

Swap
A custom-tailored, individually negotiated transaction designed to manage financial risk, usually over a period of one to 12 years. Swaps can be conducted directly by two counterparties, or through a third party such as a bank or brokerage house. The writer of the swap, such as a bank or brokerage house, may elect to assume the risk itself, or manage its own market exposure on an exchange. Swap transactions include interest rate swaps, currency swaps, and price swaps for commodities, including energy and metals. In a typical commodity or price swap, parties exchange payments based on changes in the price of a commodity or a market index, while fixing the price they effectively pay for the physical commodity. The transaction enables each party to manage exposure to commodity prices or index values. Settlements are usually made in cash.

Sweet Crude
Crude oil typically containing less than 1% sulfur, by weight.
