Options Gives the buyer the right, but not the obligation, to buy or sell stock at a set price on or before a given date. Investors, not companies, issue options. Investors who purchase call options bet the stock will be worth more than the price set by the option (the strike price), plus the price they paid for the option itself. Buyers of put options bet the stock's price will go down below the price set by the option. If the right to buy or sell the options' underlying security is not exercised with-in a specific period of time, the option expires and the buyer forfeits the money.
Orders Specific instructions for handling transactions.
Out-of-the-Money A call option is out-of-the-money if the strike price is greater than the market price of the underlying security. A put option is out-of-the-money if the strike price is less than the market price of the underlying security.
Overbought An opinion as to price levels. May refer to a security that has had a sharp rise or to the market as a whole after a period of vigorous buying which, it may be argued, has left prices "too high."
Oversold The reverse of overbought. A single security or a market which, it is believed, has declined to an unreasonable level.
Over-The-Counter (OTC) A market for securities made up of dealers who may or may not be members of a securities exchange. The OTC market is conducted over the telephone and deals mainly with stocks of companies without sufficient shares, stockholders or earnings to warrant listing on an exchange. OTC firms may act either as principals or dealers (buying or selling stock from their own inventory and charging a mark-up) or as a broker or agent and charging a commission.
