What Is an Odd Lot?
Let me tell you directly: an odd lot is a securities order with fewer shares than the standard trading unit, usually under 100 in stock transactions. You might end up with odd lots from things like reverse splits or dividend reinvestment plans. Unlike round lots, these odd lots come with higher trading commissions, which makes your transactions costlier and sometimes slower. In this piece, I'm exploring odd lots, how they form, and their impact on your trading activity.
Key Takeaways
Here's what you need to know: an odd lot in trading means purchasing fewer shares than a round lot, typically less than 100 shares. These odd lots often face higher trading commissions because of fixed minimum fees from brokerage firms. They can come about from corporate actions like reverse stock splits or dividend reinvestment plans. Unlike round lots, odd lot transactions aren't visible on bid/ask data and can take longer to execute. Companies might handle odd lots by buying them out or converting them into round lots.
How Odd Lots Develop in Trading
You could see odd lots appear in your portfolio due to reverse splits or dividend reinvestment plans. For example, if you hold 200 shares and a one-for-eight reverse split happens, you'll end up with 25 shares afterward. Even though odd lot commissions can still be high, online trading platforms have made it easier and cheaper for you to sell them.
Differences Between Odd Lots, Round Lots, and Mixed Lots
Understand this: while odd lots can include any number of shares between one and 100, a round lot is any lot of shares that can be evenly divided by 100. For instance, 75 shares would be an odd lot since it's below 100 shares, while 300 shares would count as a round lot because it divides evenly by 100.
Round lots get posted on the associated exchange, but odd lots are not posted as part of the bid/ask data. Also, the execution of odd-lot trades doesn't show up on various data reporting sources. Because of the uncommon number of shares involved, these odd-lot transactions often take longer to complete than those with round lots.
Mixed lots include lots with over 100 shares, but they can't be evenly divided by 100. Examples are 147 or 2,999 shares, both mixed lots. When reporting on mixed lots, including bid/ask data, it generally only displays the portion that makes up a round lot. So, for 147 shares, it would report as 100, and for 2,999 shares, as 2,900.
How Companies Manage Odd Lots
Since an odd lot is considered fairly insignificant to larger institutions, a company may choose to eliminate any odd holdings from the marketplace. This can involve buying out the associated shareholder at a premium, offering additional shares to you to create a round lot, or engaging in a reverse split designed to result in the odd lot becoming equivalent to less than one share, so they pay you cash for the residual holding.
The Bottom Line
To wrap this up, an odd lot in trading refers to an order quantity of less than the standard trading unit, typically under 100 shares for stocks. While these odd lots incur higher commissions and take longer to execute due to their non-standard sizes, the rise of online trading platforms has eased the process of handling them. They commonly arise from corporate actions like reverse stock splits or dividend reinvestment plans. Companies may address odd lots by offering additional shares or buyouts to streamline their shareholder base. You should be mindful of odd lots' implications on trading costs and execution speed to make informed financial decisions.
