Collar
A protective strategy in which a written call and a long put are taken against a previously owned long stock position. The options may have the same strike price or different strike prices and the expiration months may or may not be the same. For example, if the investor previously purchased XYZ Corporation at $46 and it rose to $62, a ‘collar’ involving the purchase of a May 60 put and the writing of a May 65 call could be established as a way of protecting some of the unrealized profit in the XYZ Corporation stock position. The reverse - a long call combined with a written put - might also be used if the investor has previously established a short stock position in XYZ Corporation..
Collateral
Securities against which loans are made. If the value of the securities (relative to the loan) declines to an unacceptable level, this triggers a margin call. As such, the investor is asked to post additional collateral or the securities are sold to repay the loan.

Covered option
An open short option position that is fully offset by a corresponding stock or option position. That is, a covered call could be offset by long stock or a long call, while a covered put could be offset by a long put or a short stock position. This insures that if the owner of the option exercises, the writer of the option will not have a problem fulfilling the delivery requirements.
Covered put / Covered cash-secured put
Cash secured put is an option strategy in which a put option is written against a sufficient amount of cash (or T-bills to pay for the stock purchase if the short option is assigned).
Credit
Money received in an account either from a deposit or a transaction that results in increasing the account’s cash balance.

Discretion
Freedom given by an investor through his or her Account Executive to use judgment regarding the execution of an order. Discretion can be limited, as in the case of a limit order which gives the Floor Broker 1/8 or 1/4 point from the stated limit price to use his or her judgment in executing the order.

Ex-date / Ex-dividend date
The day before which an investor must have purchased the stock in order to receive the dividend. On the ex-dividend date, the previous day’s closing price is reduced by the amount of the dividend (rounded up to the nearest eighth) because purchasers of the stock on the ex-dividend date will not receive the dividend payment. This date is sometimes referred to simply as the ‘ex-date,’ and can apply to other situations; for example, splits and distributions. If you purchase a stock on the ex-date for a split or distribution you are not entitled to the split stock or that distribution. However, the opening price for the stock will have been reduced by an appropriate amount, as on the ex-dividend date. Weekly financial publications, such as Barron’s, often include a stock’s upcoming ‘ex-date’ as part of their stock tables.
Exchange Traded Fund (ETF)
A security that tracks an index, a commodity or a basket of stocks like an index fund, but trades as a single stock on an exchange. ETFs offer the diversification benefits of a mutual fund but can be traded at any time during the day, as opposed to mutual funds, which can only be bought or sold at closing prices. The most widely traded ETF is the Nasdaq 100 Tracking Basket, which trades under the symbol QQQQ and approximates the performance of the Nasdaq 100 Index.

Expiration month
The month during which the expiration date occurs.
Fill-or-kill order (FOK)
A type of option order which requires that the order be executed completely or not at all. A fill-or-kill order is similar to an all-or-none (AON) order. The difference is that if the order cannot be completely executed (i.e., filled in its entirety) as soon as it is announced in the trading crowd, it is to be ‘killed’ (i.e., cancelled) immediately. Unlike an AON order, a FOK order cannot be used as part of a GTC order.

Immediate-or-cancel order (IOC)

After being announced, the order will be either partially or totally filled with any remaining balance immediately cancelled. An IOC order, which can be considered a type of day order, cannot be used as part of a GTC order since it will be cancelled shortly after being entered. The difference between fill-or-kill (FOK) orders and IOC orders is that a IOC order may be partially executed
Implied volatility
The volatility percentage that produces the ‘best fit’ for all underlying option prices on that underlying stock.

The contract also obligates the writer to meet the terms of delivery if the contract right is exercised by the owner.
Option pricing model
The first widely-used model for option pricing is the Black Scholes. This formula can be used to calculate a theoretical value for an option using current stock prices, expected dividends, the option’s strike price, expected interest rates, time to expiration and expected stock volatility. While the Black-Scholes model does not perfectly describe real-world options markets, it is still often used in the valuation and trading of options.

A term used to describe an option contract’s total premium when that premium is the same amount as its intrinsic value.

P/E Ratio
The P/E ratio, commonly used as a measure of common stock value, is calculated by dividing a stock’scurrent price by its annual earnings per share. For instance, if a stock is trading at $100 and its annual EPS are $5, its P/E ratio is 20. Investors often compare the P/E ratio of individual stocks to the P/E ratio of a stock index, such as the S&P 500, to determine whether a stock is over- or under-valued. The inverse of this figure is known as a stock’s earnings yield, which in this case would be 5.0%

An increase in the number of outstanding shares by a corporation, through the issuance of a set number of shares to a shareholder for a set number of shares that the shareholder already owns. For example, a corporation might declare a ‘2-for-1 stock split.’ This means that for every share of stock an investor owns, he/she will be given another, thus owning 2 shares instead of 1.
