International Securities Identification Number (ISIN)

The international standard that is used to uniquely identify securities. It consists of a two-character alphabetic country code specified in ISO 6166, followed by a nine-character alphanumeric security identifier (assigned by a national security numbering agency), and then an ISIN check-digit.

Trading Range

A trading range occurs when a stock or average moves up and down between a consistent high and low for an extended period of time (days, to weeks, to months). The bottom of the range becomes fairly solid support as the top becomes fairly solid resistance the more times either holds. We play stocks within the trading ranges if they are loose enough to give us some room to maneuver, e.g., a 5 point range or more. A tight trading range is one that is significantly narrower than a particular stock?s usual trading fluctuations. A tight trading range on low volume is usually a very good indicator that a move up is coming.

To Buy and To Sell

These are phrases used in placing orders to either buy or sell securities. If you are placing an order to purchase ten contracts of Dell October $40 calls at a limit of 4 5/8 for the day, you would tell your broker you were placing a day order for 10 contracts of Dell October $40 strike calls to buy at a limit of 4 5/8. This gives your broker all the information he or she needs to place the order.

Insider Trading

This is trading in the shares of an entity by its directors and officers. These individuals are required to disclose their trades before they happen, and several services provide this information to investors. It is useful, though not an absolute indicator as to a stock?s potential movement, to know if insiders are selling or buying shares of the company they run.

Insiders

With respect to a corporation or other entity, these are the people who have access to inside information about a company or entity that is material to the stock price. For corporations, they are typically the directors and senior officers of a corporation. A person or entity that owns greater than ten percent (10%) someone of the voting shares of a corporation is also considered an insider.
