Understanding a Special Memorandum Account (SMA)

A Special Memorandum Account (SMA) is a dedicated investment account where excess margin generated from a client’s margin account is deposited, thereby increasing the buying power for the client. Essentially, the SMA represents a line of credit and may also be known as a “special miscellaneous account.”
SMA generally equates to the buying power balance in a margin account. Buying power, also referred to as excess equity, is the money an investor has available to buy securities and equals the total cash held in the brokerage account plus all available margin.
The purpose of an SMA is to provide additional buying power in a client’s margin account. SMA exists when the margin equity in an account exceeds the Federal Reg T requirement of 50%. If the Reg T initial requirement is not met, a Fed call will be issued against the account.
Brokerage firms calculate the SMA balances of margin accounts at the end of each trading day. SMA is calculated simply as the previous day’s SMA +/- the change in current day cash, and +/- the current day trades’ initial margin requirements.
An SMA will lock in any gains realized in a client’s margin account. However, the SMA balance fluctuates.

How SMAs work

Special Memorandum Accounts (SMAs) operate as an essential financial tool within the realm of margin accounts and investments. Understanding how SMAs work is crucial for investors seeking to optimize their buying power and protect their gains.
SMA balances serve as a reflection of the buying power within a margin account. Buying power, often referred to as excess equity, signifies the financial resources available for purchasing securities. It combines the total cash available in the brokerage account with any available margin. In simpler terms, it’s the amount of money an investor can use to expand their investment portfolio.
However, the primary purpose of an SMA goes beyond just quantifying buying power. SMAs step in when the margin equity in an account exceeds the Federal Regulation T (Reg T) requirement, which mandates a minimum of 50% margin equity. If an investor’s account falls short of this requirement, it triggers a Federal Call, compelling the investor to deposit additional funds to meet the margin requirements.
Brokerage firms play a crucial role in the SMA process. They diligently calculate SMA balances on a daily basis. This calculation takes into account various elements, including the previous day’s SMA balance, changes in the cash available on the current day, and the initial margin requirements for any trades executed on that particular day.
One distinctive feature that sets SMAs apart is their ability to act as a safeguard for gains realized in a client’s margin account. When a client achieves capital gains through their investments, the SMA locks in these gains. This means that even if the market takes a downturn in the future, the gains already made are protected. However, it’s important to note that SMA balances aren’t static; they can fluctuate due to various factors.
These factors include, but are not limited to:
  • Cash deposits: Additional cash deposits into the brokerage account can increase the SMA balance, providing more buying power.
  • Interest and dividend payments: SMAs may accumulate interest and dividend payments from long positions, contributing to their value.
  • Securities transactions: Any transactions within the margin account, such as buying or selling securities, can influence SMA balances.
It’s important for investors to recognize that while SMAs offer distinct advantages, they also come with considerations and potential risks, which will be further explored in the following sections.

Special considerations

Consider the situation where stock within a client’s margin account realizes a capital gain and creates excess margin. If this excess amount is held in the account, and the stock position produces a capital loss at a later date, the client could then lose their gain entirely.
The SMA balance increases in value with cash deposits into the brokerage account. The SMA also holds interest and dividend payments from long positions and proceeds from closing out a securities position.
Clients can use funds in their SMA to purchase additional securities for their margin account. The SMA balance decreases with cash withdrawals from the brokerage account and when buy orders for securities are executed.

The bottom line

Special Memorandum Accounts (SMAs) are a powerful financial tool that can significantly enhance an investor’s buying power and provide a safety net for gains in their margin accounts. Understanding how SMAs work and their potential benefits and drawbacks is essential for anyone involved in margin trading and investments.
SMAs, by mirroring buying power, allow investors to seize opportunities in the market and diversify their portfolios. They step in when margin equity exceeds the Federal Regulation T (Reg T) requirement, preventing Federal Calls and additional fund requirements.
Brokerage firms play a vital role in the daily calculation of SMA balances, ensuring they accurately reflect the investor’s financial situation. This includes considering the previous day’s SMA balance, changes in cash, and margin requirements for new trades.
Perhaps one of the most appealing aspects of SMAs is their ability to lock in gains. This feature provides investors with peace of mind, knowing that their hard-earned profits are protected even if the market takes an unexpected turn.
However, it’s crucial to keep in mind that SMA balances aren’t static. They can fluctuate due to various factors, including cash deposits, interest and dividend payments, and securities transactions within the margin account.
Investors should approach SMAs with careful consideration. While they offer advantages such as increased buying power and gain protection, there are risks associated with mismanagement and fluctuating balances. Proper management and understanding the dynamics of SMAs are key to maximizing their benefits.
In conclusion, SMAs are a valuable tool in the world of investments and margin accounts. When used wisely, they can empower investors to make strategic moves in the market while safeguarding their financial gains.
