What Is a Margin Call?
A margin calloccurs when the percentage of an investor’s equity in a margin account falls below the broker’s required amount. An investor’s margin account contains securities bought with a combination of the investor’s own money and money that was borrowed from the investor’s broker.
A margin call refers specifically to a broker’s demand that an investor deposit additional money or securities into the account so the value of the investor's equity and the account value rise to a minimum value indicated by the maintenance requirement.
A margin call is usually an indicator that the securities held in the margin account have decreased in value. The investor must choose to either deposit additional funds or marginable securities in the account or sell some of the assets held in their account when a margin call occurs.
Key Takeaways
- A margin call occurs when a margin account runs low on funds, usually because of a losing trade.
- Margin calls are demands for additional capital or securities to bring a margin account up to the maintenance requirement.
- Brokers may force a trader to sell assets, regardless of the market price, to meet the margin call if the trader doesn’t deposit funds.
- Margin calls can also occur when a stock goes up in price and losses start mounting in accounts that have sold the stock short.
- Investors can avoid margin calls by monitoring their equity and keeping enough funds in their accounts to maintain the value above the required maintenance level.
What Triggers a Margin Call?
An investor is buying on margin when they pay to buy and sell securities using a combination of their own funds and money borrowed from a broker. An investor’sequity in the investment is equal to the market value of the securities minus the borrowed amount.
A margin call is triggered when the investor’s equity as a percentage of the total market value of securities falls below a certain required level called the maintenance margin.
The New York Stock Exchange (NYSE) and the Financial Industry Regulatory Authority (FINRA), the regulatory body for the majority of securities firms operating in the United States, both require that investors maintain an equity level of 25% of the total value of their securities when buying on margin. Some brokerage firms require a higher maintenance requirement, as much as 30% to 40%.
Margin calls can occur at any time due to a drop in account value but they're more likely to happen during periods of market volatility.
Example of a Margin Call
Here's an example of how a change in the value of a margin account decreases an investor's equity to a level where a broker must issue a margin call.
Drop in value triggers a margin call by broker | ||||
---|---|---|---|---|
Security Value | Loan Amount | Equity ($) | Equity (%) | |
Security bought for $20,000 (half on margin) | $20,000 | $10,000 | Investor Equity = $10,000 | Investor Equity = 50% |
Value drops to $14,000 | $14,000 | $10,000 | $4,000 | Investor Equity = 28% |
Maintenance requirement of broker | $14,000 | $4,200 | 30% | |
Resulting margin call | $200 |
How to Cover a Margin Call
The investor typically has two to five days to act if their account value drops to a level where a margin call is issued by their broker. These are the options for doing so using the margin call example above:
- Deposit $200 in cash into the account.
- Deposit $285 of fully paid-for marginable securities into the account. This amount is derived by dividing the required funds of $200 by 1 less the 30% equity requirement: 200/(1-.30) = $285.
- Use a combination of the above two options.
- Sell other securities to obtain the needed cash.
A broker may close out any open positions to replenish the account to the minimum required value if an investor isn't able to meet the margin call. They may be able to do this without the investor’s approval. The broker may also charge an investor a commission on these transaction(s). The investor is held responsible for any losses sustained during this process.
The amount of a margin loan depends on a security's purchase price and is therefore a fixed amount. But the dollar amount determined by the maintenance margin requirement is based on the current account value, not on the initial purchase price. That's why it fluctuates.
How to Avoid a Margin Call
Investors should carefully consider whether they need a margin account before opening one. Most long-term investors don't have to buy on margin to earn solid returns. And these loans aren't free. Brokerages charge interest on them.
But there are a few things you can do to manage your account, avoid a margin call, or be ready for it if you want to invest with margin:
- Make sure cash is available to place in your account immediately. Consider keeping it in an interest-earning account at the same brokerage.
- Build a well-diversified portfolio. This may help limit margin calls because a single position is less likely to decrease the account value.
- Monitor your open positions, equity, and margin loans regularly, even daily.
- Create a custom-made alert at some comfortable level above the margin maintenance requirement. Deposit funds or securities to increase your equity if your account falls to it.
- Take care of it immediately if you receive a margin call.
A good way for an investor to avoid margin calls is to use protective stop orders to limit losses in any equity positions in addition to keeping adequate cash and securities in their account.
Is It Risky to Trade Stocks on Margin?
It's certainly riskier to trade stocks with margin than without it because trading stocks on margin is trading with borrowed money. Leveraged trades are riskier than unleveraged ones. The biggest risk with margin trading is that investors can lose more than they've invested.
How Can a Margin Call Be Met?
A margin call is issued by the broker when there's a margin deficiency in the trader’s margin account. The trader has to either deposit cash or marginable securities in the margin account or liquidate some securities in the account to rectify a margin deficiency.
Can a Trader Delay Meeting a Margin Call?
A margin call must be satisfied immediately and without any delay. Some brokers may give you two to five days to meet the margin call but the fine print of a standard margin account agreement will generally state that the broker has the right to liquidate any or all securities or other assets held in the margin account at its discretion and without prior notice.
It's best to meet a margin call and rectify the margin deficiency promptly to prevent such forced liquidation.
How Can I Manage the Risks Associated With Trading on Margin?
Measures to manage the risks associated with trading on margin include:
- Using stop-loss orders to limit losses
- Keeping the amount of leverage to manageable levels
- Borrowing against a diversified portfolio to reduce the probability of a margin call which is significantly more likely with a single stock
Does the Total Level of Margin Debt Have an Impact on Market Volatility?
A high level of margin debt can exacerbate market volatility. Clients are forced to sell stocks to meet margin calls during steep market declines. This can lead to a vicious circle where intense selling pressure drives stock prices lower, triggering more margin calls and more selling.
The Bottom Line
Buying on margin isn't for everyone. Not all investors will have available funds to reach initial and maintenance margins on margin trading accounts. It can give investors more bang for their buck but there are downsides.
It's only an advantage if your securities increase enough to repay the margin loan and the interest on it. Another headache can be the margin calls for funds that investors must meet.
A margin call may require you to deposit additional cash and securities. You may even have to sell existing holdings or you may have to close out the margined position at a loss. Margin calls can occur when markets are volatile so you may have to sell securities to meet the call at lower-than-expected prices.
