How Margin Debt Works
Money that is borrowed to buy stocks is sometimes an indicator of future market performance. Here is how it works and why the matter is relevant now.

Margin debt is a sometimes-overlooked but key part of the stock market that is particularly pertinent right now.
It is the money that investors borrow from stockbrokers to buy securities when they can’t or don’t want to fund the entire purchase with cash. Say an investor wants to purchase 100 shares at $50 each for a total of $5,000 but has only $2,500 to invest. That individual could buy the rest of the shares on margin. The same process can be used to buy exchange-traded funds.
Investors frequently use margin to get more bang for their investing buck. “The pro of margin is that it increases your purchasing power,” says Jeff Deiss, director of wealth planning at ACM in Ridgewood, N.J.
The downside is that brokers typically charge interest on borrowed money. And if the individual starts losing money on the investment, the stockbroker might ask for additional cash as security or collateral. That decision and how much cash will be required will depend on a variety of factors, including the remaining value of the investment, how much money the investor owes the broker and the requirements of the broker.
“Buying on margin comes with a lot of risk, and if you are going to use margin, it is probably a good idea to have some cash on the side,” says Mr. Deiss. Investors who don’t have the required additional cash may be forced to close out their positions at a loss.
A large amount of buying on margin also can be detrimental to the stock market as a whole.

At the end of January, customer margin debt at U.S. brokers regulated by the Financial Industry Regulatory Authority, or Finra, jumped to $799 billion from $562 billion a year earlier, according to data provided by Finra.
Some analysts say that jump in margin debt came from individual investors, who turned to online trading amid pandemic-related lockdowns. A combination of new easy-to-use trading technology, ultralow borrowing costs and stimulus checks from the federal government helped fuel the phenomenon.
“For younger folks, it’s kind of the drug of choice,” Mr. Deiss says.
The problem is, when there is a lot of margin debt concentrated in a few stocks, those stocks tend to see wild price swings, says Fabiana Fedeli, global head of fundamental equities at Rotterdam-based asset-management company Robeco. Anecdotal evidence indicates that the recent increase in margin debt coincided with higher participation levels by individual investors, she says.
Indeed, certain stocks that became popular with individual investors also saw price volatility earlier this year. “The minute that the margin couldn’t be met, some of the positions had to be sold immediately,” Ms. Fedeli says. “It gives volatility to the market,” she says.

With US$40 million already committed, the Global Talent Fund is attracting investor attention with a strategy focused on building globally scalable consumer brands alongside high-profile talent.
A new investment fund targeting celebrity-founded consumer brands has secured US$40 million in commitments and is rapidly approaching its US$50 million fundraising target, signalling growing investor appetite for alternative opportunities beyond traditional asset classes.
The Global Talent Fund, which has a maximum raise of US$100 million, focuses on building and investing in consumer businesses alongside celebrities, athletes, and influential personalities who play an active role as co-founders rather than simply endorsing products.
The strategy is based on the belief that changes in consumer behaviour, particularly the rise of social media and digital engagement, have fundamentally altered how brands are built and scaled.
GTF founding partner Jeremy Hunt, who is helping lead the fund’s strategy, said consumers increasingly feel connected to personalities they follow online and are more willing to support products developed by those individuals.
“Consumers are searching for content to engage with, and when a celebrity they like or follow takes them on the journey of creating a product or brand, they genuinely feel part of that process,” he said.
The fund is targeting high-growth consumer sectors including wellness, hydration, beauty and recovery, areas Hunt believes continue to benefit from strong global demand and ongoing innovation.
Rather than backing celebrity endorsement deals, the fund is seeking businesses where talent is deeply involved in product development, brand creation and long-term growth.
According to Hunt, authenticity remains one of the biggest differentiators between successful celebrity-backed brands and those that fail.
“The consumer can see clearly if someone is simply being paid to promote a product,” he said. “The winners are typically the brands where the celebrity has genuinely helped build the business from the ground up.”
The model has attracted support from several prominent Australian investors and business families, reflecting broader interest in alternative investments with global growth potential.
Hunt said consumer brands offered a level of tangibility that many investors found appealing.
“Consumer brands are what we touch, feel, smell and taste every day,” he said. “Our investors understand the growth potential in the model, but they also want to be part of the journey.”
The fund’s rapid progress towards its fundraising target comes amid growing recognition that celebrity influence, when combined with strong commercial execution and scalable business models, can create significant enterprise value.
With several high-profile celebrity-founded businesses generating billion-dollar exits in recent years, supporters of the strategy believe the opportunity remains in its early stages.
