Normalized Earnings

Profits a company can be expected to achieve taking out cyclical effects and unusual events such as one-time write-offs caused by late product releases, customer bankruptcies and the like. 

Odd Lot

A block of stock consisting of less than 100 shares. When odd lots trade, a premium is usually tacked on by the specialist or market maker. These receive the least favorable price and trade last.

On-Stop (O/S) Order

A special-term order placed with the intention of trading at a later date when the price of the stock reaches the specified stop price. An on-stop order becomes a limit order once a trade at the trigger price has occurred.
