Most people his age are still figuring out their overdraft. Zack Islam, aged 22, has built a fully self-funded investment portfolio valued at approximately £700,000. Concentrated in high-conviction positions in AI and space, his portfolio reflects relentless, disciplined research, long-term patience, and fearless strategic risk-taking—all while self-funding his education as a first-generation, state-schooled university student from humble beginnings. With no safety net, no family wealth to fall back on and against conventional investment advice, he trusted his own analysis.
Born in Small Heath, Birmingham and growing up in Luton, Zack was raised in a low-income Bangladeshi household of six. His dad was a taxi driver. His mum was unemployed. The family relied on benefits. Zack qualified for free school meals and attended a nationally underperforming state school with minimal university progression rates.
In 2022, he was admitted as a first-generation university student at the University of Exeter’s Penryn Campus, graduating in summer 2025. His parents couldn’t contribute financially — so he didn’t ask them to. Instead, he balanced multiple jobs and side hustles alongside a full-time degree.
Here’s where it gets real: particularly during his first year, Zack occasionally skipped meals. “I’d go to sleep still hungry and drink lots of water to try to quench that hunger,” he recalls. Daily living expenses were tightly rationed. Social events were missed. Bus rides were sometimes swapped for long walks — which he mentally reframed as exercise, just to stretch his budget a bit further. Every pound counted because there weren’t many of them. These challenges taught him to seize every opportunity when they came round, maximize limited resources, and extract value from every chance he was given.
Before university, Zack had already started earning. Greggs at 17. Night shifts at a DPD warehouse at 18. Then McDonald’s early mornings, a catering job on campus, and student ambassador work layered on top of a full bioscience degree. “I was up for 6 am Saturday shifts at McDonald’s Falmouth, watching classmates stumble off the bus from Friday night partying” he says. During the summer, winter, and Easter holidays, Zack continued agency work in catering and warehouses, steadily gaining experience and income. He says “I lived extremely frugally, minimizing daily expenses, utilising offers, discounts, giftcards to maximize the limited capital I could deploy”
By the start of his second year of university, he committed fully to investing, personal growth, and building his career prospects, eager to change his life.
Evenings were dedicated to learning about the stock market. YouTube tutorials on finance. Paper trading accounts. Earnings calls for the Magnificent Seven. Studying the impact of industry trends and geopolitical developments. Benjamin Graham’s The Intelligent Investor. He tracked every pound in a monthly Excel spreadsheet from mid-2023 onward — milestones mapped out, motivation maintained. While his portfolio was extremely volatile, he describes his strategy as a calculated risk that ultimately paid off.
Zack believes the stock market can seem confusing at first and is often misunderstood. But he argues it does not have to be complicated. In his view, the UK’s general attitude towards investing remains poor, even though the stock market can be transformational, and potentially life-changing, when approached intelligently, patiently and strategically.
Alongside part-time and zero-hours work, competitive scholarships helped too. A £9,000 University of Exeter Achievement Award, a £5,000 J.P. Morgan/Sutton Trust Opportunity Bursary, and £6,600 from the Exeter Access Bursary across three years. He also received the maximum maintenance loan. Combined with minimal living costs, these funds gave Zack early capital to deploy and the opportunity to leverage every pound strategically rather than spend impulsively.
His first real investing lesson came the hard way. He bought Cineworld shares post-COVID — chasing social media hype, skimping on research. Those shares went to zero. It hurt. Hard earned capital gone just like that. Rather than walk away or seek revenge, Zack treated it as tuition which shaped his later success.
He targeted underappreciated stocks with massive growth potential, similar to investing in Tesla before the market recognized its potential. He focused on sectors he believed would dominate the future—space and AI/data—concentrating roughly 99% of his portfolio in two highly volatile stocks:
Rocket Lab and Palantir.
He bought Rocket Lab shares at $3–$5, now trading at around $126. That’s roughly a 2,800% return – generating him £485,000 in profit.
Palantir shares, purchased at $9–$10, now trading at $140, peaking at $200 has added around £14,000 in profit. A return of around 1,000%.
Daily swings of £30,000–£50,000 are routine for Zack now. After one recent Rocket Lab earnings report, he made £110,000 profit in just 24 hours.
His biggest week saw his portfolio rise by around £190,000.
Overall, his self-funded portfolio fluctuates between £550,000–£650,000, peaking at around £700,000.
The catch? He’d be the first to tell you this wasn’t a simple formula.
“I recognize the role of luck and the bull market, but I also trusted my gut and deep analysis to carry me through,” he reflects. “Diversification and safe bets can come later when I have a wife and kids to look after. Right now, there are no stakes beyond myself. If I lost it all, it would only affect me—and I’m okay with that. I also trust myself enough where if I lost it all, I can make it back in other ways. This isn’t gambling; it’s disciplined, research-driven conviction. Managing mindset is just as important as understanding the market. I knew that if I wanted a real chance at financial freedom, the time to act with a higher risk tolerance was now.”
He promised himself he wouldn’t consider selling for at least five years. Short-term volatility, he figured, gets overwritten by long-term patience if the underlying thesis is strong.
What drives Zack isn’t the portfolio balance. It’s his deep passion for social mobility and being a positive role model for others. “I’ve received tremendous support from social mobility charities, widening access schemes and mentors to overcome the limitations of my background,” he says. “I see many younger versions of myself in society and want to show them what’s possible. Discipline, patience, and strategic risk-taking are values I hope to instill in today’s youth.”
In recognition of his wide array of work, he was named University of Exeter Student of the Year in 2024 and won a National Student Social Mobility Award in 2025. He now chairs the upReach Alumni Ambassador Board and sits on the Sutton Trust Alumni Leadership Board, shaping national policy on access and opportunity for those from lower socio-economic backgrounds.
Through persistence, Zack secured a summer internship at J.P. Morgan’s Investment Bank in Canary Wharf. Seeing that kind of money hit his account for the first time was, by his own description, a shock. But rather than giving in to lifestyle inflation, he reinvested it almost immediately.
That discipline has stayed with him. He later entered a graduate asset management role, carrying the same mentality forward: live below his means, stay patient, and make every pound work as hard as possible.
“I want my journey to show the youth from low-income backgrounds not to lose hope. Anything is possible if you truly commit. Maybe not today, maybe not tomorrow, but eventually, your actions will pay off. I’m seeing this in real time right now. Dedication behind the scenes is what counts. Always maintain a can-do mindset—it carries you through challenges, no matter their size.”
His parents’ sacrifices stay with him. “Even with so little, they poured every ounce of love, care, and opportunity into my upbringing,” he says. “Their sacrifices define who I am today. I am determined to honour them by making their dreams a reality.”
For Zack, the numbers are almost secondary. “It’s not even the financial success that matters most. It’s the kind of person I’ve become through these struggles. Financials are just a byproduct of that journey.”
Zack’s journey is not simply a story of incredible investment returns. It is a story of hunger, discipline, sacrifice and belief. From free school meals to a portfolio now worth almost three quarters of a million, he is proof that talent is everywhere, but opportunity is not, and that when opportunity finally meets preparation and discipline, the results can be life-changing.

His outcome was shaped by research, timing, market conditions, risk tolerance and luck, and should not be assumed to be suitable or replicable for most investors. Past performance is not indicative of future results. The value of investments can fall as well as rise, and investors may get back less than they put in.
