Ratio Spread

See Also:

Spread: Spread (Also referred to as Straddle) is the purchase of one futures delivery month against the sale of another futures delivery month of the same commodity; the purchase of one delivery month of one commodity against the sale of that same delivery month of a different commodity; or the purchase of one commodity in one market against the sale of the commodity in another market, to take advantage of a profit from a change in price relationships. The term spread is also used to refer to the difference between the price of a futures month and the price of another month of the same commodity. A spread can also apply to options.

A spread is the simultaneous purchase and sale of the same or similar commodity, in different or the same contract months. Spread trading is usually considered to be a lower risk strategy than an outright long or short futures position, and therefore margin requirements are usually less.

Not only can spreads be utilized in futures markets, but options provide even more opportunities for successful spread trading. With so many variables including strike prices, trading months, and different markets available, the permutations and combinations of option strategies are tremendous.

Some of the advantages of spreads are:
 - require smaller margin deposits;
 - lower risk
 - seasonal patterns exist among spread relationships.

Back Spread: Back Spread is a delta-neutral ratio spread in which more options are bought than sold. A back spread will be profitable if volatility increases. See Delta.

Call: There are three meaning of the "Call" term. It could be:
1) An option contract giving the buyer the right but not the obligation to purchase a commodity or other asset or to enter into a long futures position;
2) a period at the opening and the close of some futures markets in which the price for each futures contract is established by auction;
3) the requirement that a financial instrument be returned to the issuer prior to maturity, with principal and accrued interest paid off upon return.

Delta: Delta is the expected change in an option's price given a one-unit change in the price of the underlying futures contract or physical commodity. For example, an option with a delta of 0.5 would change $.50 when the underlying commodity moves $1.00.

Delta Neutral: Delta neutral refers to a position involving options that is designed to have an overall delta of zero.

Front Spread: Front Spread is a delta-neutral ratio spread in which more options are sold than bought. Also called ratio vertical spread. A front spread will increase in value if volatility decreases.

Option: Option is a contract that gives the buyer the right, but not the obligation, to buy or sell a specified quantity of a commodity or other instrument at a specific price within a specified period of time, regardless of the market price of that instrument. There are two types of options: Put Options and Call Options.

Put: Put is an option contract that gives the holder the right but not the obligation to sell a specified quantity of a particular commodity or other interest at a given price (the "strike price") prior to or on a future date. Call options is another type of options.

Strike Price: Strike Price (Exercise Price) is the price, specified in the option contract, at which the underlying futures contract, security, or commodity will move from seller to buyer. Strike Price is the price at which the buyer of a call (put) option may choose to exercise his right to purchase (sell) the underlying futures contract.
