An odd lot refers to an order amount for a security that is less than the standard unit of trading established by a particular market. This term is predominantly used in the context of stock trading, but it can apply to other securities as well, such as bonds and commodities.
Definition and Characteristics
Standard Trading Unit
In financial markets, securities are typically traded in standard units, known as round lots. For example, a round lot in the stock market generally consists of 100 shares. Any order that does not meet this unit criteria is classified as an odd lot.
Causes of Odd Lots
Odd lots often arise from partial sales or purchases of securities, inheritance, trading mistakes, reinvested dividends, or systematic investments over time.
Types of Odd Lots
Incomplete Sales
Investors may choose to sell a portion of their holdings that do not meet the round lot requirements, resulting in the remaining portion being classified as an odd lot.
Fractional Share Purchases
With the rise of fractional share investing platforms, it’s increasingly common for investors to purchase odd numbers of shares which produce odd lots.
Special Considerations
Trading Fees
Historically, odd lot orders could incur higher transaction fees compared to round lots. Modern trading platforms have made this less common, but investors should still remain cautious.
Liquidity Concerns
Odd lot orders might face liquidity issues due to the non-standard size, potentially resulting in less favorable price executions.
Examples
Consider an investor who owns 150 shares of Company XYZ. If they sell 55 shares, they are left with 95 shares, which is an odd lot.
Historical Context
Odd lots have been significant in market history, especially when manual trading was predominant. With electronic and algorithmic trading, the distinction between odd and round lots has diminished in practical terms.
Applicability in Modern Markets
Algorithmic Trading
Advanced algorithms today can handle odd lots efficiently, making them less problematic for execution than in the past.
Fractional Shares
Brokerage platforms offering fractional shares, especially utilized by retail investors, have made odd lots more prevalent.

Block Trade
A block trade involves a significantly larger number of securities, usually 10,000 shares or more. This is in direct contrast with odd lots and highlights trading variability.
