What Is a Lot in Securities Trading?
Let me tell you directly: in securities trading, a lot simply means the number of units of a financial instrument you're buying or selling on an exchange. It's conveyed by the lot name, and while a round lot for stocks is 100 shares, you don't have to stick to that—you can trade any number, even if it's an odd lot under 100 shares.
How a Lot Works
You need to understand that lots are fixed quantities depending on the security. Back in the day, stocks traded in round lots of 100 shares, but with online trading, odd lots and mixed lots are routine. For instance, an odd lot is less than 100 shares, and a mixed lot is over 100 but not divisible by 100. The same goes for ETFs, where the round lot is also 100 shares.
Types of Lots
Now, let's break down the types based on what you're trading. For bonds, institutional investors deal in round lots of $100,000 or $1 million, but you as an individual can buy bonds with face values as low as $1,000—it's still considered an odd lot if it's not the full round amount.
In options, one lot equals 100 shares of the underlying stock per contract. So, if you buy a call option on Bank of America at a $24.50 strike and exercise it when the stock's at $26.15, you're getting 100 shares at that price.
Futures lots are contract sizes fixed by the exchange—like 5,000 bushels for corn or 100,000 CAD for a Canadian dollar contract. You can't negotiate these; they're standardized for liquidity.
For forex, you have micro lots of 1,000 base currency units, mini lots of 10,000, and standard lots of 100,000. Brokers might let you trade in increments of 1,000, but that's the minimum.
Frequently Asked Questions
- Is it better to invest in bonds or stocks? It depends on your timeline—stocks for long-term growth, bonds for short-term safety.
- What is a lot in forex trading? It's traded in micro (1,000), mini (10,000), or standard (100,000) units of the base currency.
- What are futures? They're contracts to buy or sell an asset at a future date for a price set now, often involving delivery.
The Bottom Line
To wrap this up, lots matter differently depending on the market. In options and futures, you're locked into contract sizes, but in stocks and forex, you have flexibility with odd lots. Remember, standardization boosts liquidity, making trading efficient for everyone involved.
