These Teenagers Know More About Investing Than You Do

Seventeen-year-old Sophia Castiblanco doesn’t just drive a Tesla . She also owns shares of the company .

Sophia, a high school junior in the Chicago suburbs, invests in stocks such as Tesla, Apple and Amazon.com. When she started making money as a social-media content creator three years ago, her parents encouraged her to put some of her earnings in investments likely to grow over time, rather than parking all her cash in a savings account .

She now has several thousand dollars invested in accounts set up by her father at Charles Schwab, Edward Jones and Robinhood . Last year, she saved up money to buy a new Tesla Model 3, which starts at around $40,000, through a payment plan she is splitting with her parents. On TikTok, Instagram and YouTube, she makes videos teaching her thousands of followers about investing basics.

“I’ve always had a business mindset of wanting to make money, and I’m very OK with taking risk,” Sophia said. “There’s really no minimum age to start.”

Sophia is one of many teenagers jumping into the U.S. stock market. Teens generally can’t open their own brokerage accounts until they turn 18, but adults can set up custodial accounts for minors. The accounts are turned over to the children when they reach legal age.

Custodial accounts for teens at Schwab totalled nearly 200,000 in 2022, up from about 120,000 in 2019, according to the company. They jumped above 300,000 in 2023, thanks in part to Schwab’s integration of TD Ameritrade. Other brokerages, including Vanguard, Fidelity and Morgan Stanley’s E*Trade, also reported a surge in custodial accounts in recent years.

Some teens ask their parents to open accounts—and share the login information—at brokerages such as Robinhood that don’t offer custodial accounts. At smaller financial apps such as Greenlight, teenagers are investing more money than ever before. They invested $20 million in 2023 using the Greenlight app, up from around $10 million in 2021.

A Fidelity study on teens and money recently estimated that about a quarter of teenagers in the U.S. have started investing, based on an online survey of 2,081 respondents ages 13 to 17. Trades placed using Fidelity’s Youth app, an account opened by parents but owned by teens, jumped in the fourth quarter.

Many teenagers opened up their accounts during winter break while off from school, said Kelly Lannan, a senior vice president at Fidelity.

The boom in teen trading is part of a wider rush to financial markets among Americans since the start of the Covid-19 pandemic. Stocks rocketed higher , drawing hordes of newbie investors trying to profit from the big gains.

Many of those new investors have since ditched the meme stocks that soared during that era but have remained invested, sending the share of Americans who own stocks to an all-time high.

Stocks are back at record levels, with the Dow Jones Industrial Average recently topping 38000 and the S&P 500 eclipsing 5000 for the first time. Since the start of 2020, when an unprecedented trading boom among rookie investors kicked off, the S&P 500 has soared around 55%.

“There’s just more and more awareness that the sooner you start, the better things are,” said James Martielli, head of investment and trading services at Vanguard.

Martielli said he opened custodial accounts for his three children more than a decade ago when they were toddlers. At Vanguard, there has been a jump in custodial IRAs, a type of retirement account.

The biggest advantage is time. Setting aside $10 a week for a child at birth would leave an 18-year-old with a roughly $20,000 nest egg, assuming an 8% annual return, according to the investing app Stash, which offers custodial accounts. Left until the investor turned 70, and assuming annual growth of 8%, that sum would mushroom to about $1 million.

Of course, these returns can be shaped by many factors, including when an investor buys in and how stocks end up doing. The S&P 500 has recorded a 10% annualised total return over the past three decades, according to Dow Jones Market Data through the end of 2023. Buying an S&P 500 index fund at the peak of the dot-com bubble in 2000 would generate an annualised total return of around 7%, while buying at the low of the financial crisis in 2009 would lead to a roughly 16% annualised total return.

Hot tech stocks

Brokerage executives say that technology behemoths that are ubiquitous in the lives of teens are often some of the most widely held shares. At Vanguard, U.S. stock index funds are particularly popular in custodial accounts.

Mahanth Komuravelli, 16, has a small chunk of his roughly $7,000 portfolio in an S&P 500 index fund, while most of his positions are in big companies such as Amazon and Advanced Micro Devices. He is exploring buying some small-cap stocks such as education company Chegg . Mahanth uses a Fidelity Youth Account that his father helped him open. The two often discuss investment ideas.

“Sometimes he asks me for advice,” said Mahanth, a high school junior in Edison, N.J.

Kaida Benes, a 13-year-old from the suburbs of Minneapolis, has been stashing money—earned from household chores such as doing the dishes or cleaning the bathroom—in an investment account on Greenlight that now has about $1,000 in it.

She’s also been drawn to bigger companies and has invested in tech stocks such as Apple, Alphabet and streaming companies Disney and Netflix . At times, she has been on edge about potential losses. She says her mother has helped her stomach the volatility.

“Stocks go up and down. It’s fine, it just happens,” Kaida said she’s learned.

She has been hunting for other opportunities to make money to pour into savings or investments. She recently found a recliner chair at a yard sale and enlisted her parents to help fix it up and flip it for a profit on Facebook marketplace, she and her mother, Renee Benes, said.

“I like having money,” Kaida said.

Renee Benes said she was frustrated that she didn’t learn about investing until a year or two ago, when she was well into her 30s. Benes, who’s an online influencer, wanted her daughter and son to be more financially savvy.

Lessons learned

Many young investors are starting to invest earlier than previous generations did. Almost two-thirds of Gen Z investors said they first started learning about investing in high school or middle school, compared with about 38% of millennials in a 2023 Bank of America survey of affluent individuals. Some are introduced to stocks through family members or teachers, while others have turned to social media.

Felix Peng, a 17-year-old in the Los Angeles area, said he has learned a lot about investing from YouTube and Instagram—but that some social-media stars promote riskier trading strategies that seem more like gambling. He said it is a red flag when influencers try to sell expensive trading courses that promise investors they will make a lot of money quickly.

Still, Felix believes it is beneficial for young people to learn from their mistakes when they have less money to lose. His investments in Apple, Meta Platforms and Alphabet have performed well. But when he bought shares of Teladoc around their peak and watched them tumble, he saw how tough it is to time the market. He has about $1,000 in a custodial account on Stockpile, an investing app geared toward parents and children.

“It’s a great lesson and I’m glad I learned,” Felix said.

Seventeen-year-old Rachael Kim in Orange County, Calif., traded shares of AMC Entertainment Holdings during the meme-stock era and said she made a roughly 300% profit.

“For a little while, I got addicted to that adrenaline,” Rachael said of day trading. “But as I began researching more, I realised it was highly unlikely to continue that aggressive profit.”

Rachael said she started studying investing to help her parents, who are immigrants, prepare for retirement. Now she regularly invests about half of the money she makes—from creating social-media content, working as a cashier and teaching at her church—in index funds tracking the S&P 500 and tech-heavy Nasdaq-100. She has about $10,000 in her custodial Roth IRA at Fidelity.

“Since we’re young, we have the privilege of seeing our investment compound,” Rachael said. “The biggest lesson would be to start early.”

Family offices are increasingly asserting their dominance in Australia’s private credit markets, particularly in the commercial real estate debt (CRED) segment.

With more than 2,000 family offices now operating nationally—an increase of over 150% in the past decade, according to KPMG—their influence is not only growing in scale, but also in strategic sophistication.

Traditionally focused on preserving intergenerational wealth, COI Capital has found that family offices have broadened their mandates to include more active and yield-driven deployment of capital, particularly through private credit vehicles.

This shift is underpinned by a defensive allocation rationale: enhanced risk-adjusted returns, predictable income, and collateral-backed structures offer an attractive alternative to the volatility of public markets.

The Competitive Landscape for Manager Mandates

As family offices increase their exposure to private credit, the dynamic between managers and capital providers is evolving. Family offices are highly discerning capital allocators.

They expect enhanced reporting, real-time visibility into asset performance, and access to decision-makers are key differentiators for successful managers. Co-investment rights, performance-based fees, and downside protection mechanisms are increasingly standard features.

While typically fee-sensitive, many family offices are willing to accept standard management and performance fee structures when allocating $5M+ tickets, recognising the sourcing advantage and risk oversight provided by experienced managers. This has created a tiered market where only managers with demonstrated execution capability, origination networks, and robust governance frameworks are considered suitable partners.

Notably, many are competing by offering differentiated access models, such as segregated mandates, debt tranches, or tailored securitisation vehicles.

Onshore vs. Offshore Family Offices

There are important distinctions between onshore and offshore family offices in the context of CRED participation:

Onshore Family Offices: Typically have deep relationships with local stakeholders (brokers, valuers, developers) and a more intuitive understanding of planning, legal, and enforcement frameworks in Australian real estate markets. They are more likely to engage directly or via specialised mandates with domestic managers.
Offshore Family Offices: While often attracted to the yield premium and legal protections offered in Australia, they face structural barriers in accessing deal flow. Currency risk, tax treatment, and regulatory unfamiliarity are key concerns. However, they bring diversification and scale, often via feeder vehicles, special-purpose structures, or syndicated participation with Tier 1 managers.

COI Capital Management has both an offshore and onshore strategy to assist and suit both distinct Family Office needs.

Impact on the Broader CRED Market

The influx of family office capital into private credit markets has several systemic implications:

Family offices, deploying capital in significant tranches, have enhanced liquidity across the mid-market CRE sector.
Their ability to move quickly with minimal conditionality has contributed to yield compression, particularly on low-LVR, income-producing assets.
As a few family offices dominate large allocations, concerns emerge around pricing power, governance, and systemic concentration risk.

Unlike ADIs or superannuation funds, family offices operate outside the core prudential framework, raising transparency and risk management questions, particularly in a stress scenario.

So what is the answer? Are Family Offices the most Attractive?

Yes—family offices are arguably among the most attractive funding partners for CRED managers today. Their capital is not only flexible and long-term focused, but also often deployed with a strategic mindset.

Many family offices now have a deep understanding of the risk-return profile of CRE debt, making them highly engaged and informed investors.

They’re typically open to co-investment, bespoke structuring, and are less bogged down by institutional red tape, allowing them to move quickly and decisively when the right opportunity presents itself. For managers, this combination of agility, scale, and sophistication makes them a valuable and increasingly sought-after partner in the private credit space.

For high-performing CRED managers with demonstrable origination, governance, and reporting frameworks, family offices offer not only a reliable source of capital but also a collaborative partnership model capable of supporting large-scale deployments across market cycles.
