Over the last decade, my portfolio has crushed the market. But it wasn't always like this.
When I started investing, I was completely lost. I still remember the first time I bought a stock. I had no idea what I was doing. I just bought a stock I read about in an article and hoped it would work out.
Turns out, hope is not a great investing strategy.
I made all the classic mistakes:
I spent years reading books, watching videos, and trying to piece together a strategy. But the more I learned, the more overwhelmed I felt.
Then something clicked. I realized that successful investing isn't about chasing hot tips or memorizing financial ratios. It's about having a simple, repeatable process.
So I built one. I call it the ADAPT framework, and it changed everything. Once I started using it, I could finally:
Now I want to share everything I've learned with you.

Brian's investing style was shaped by three of the greatest investment thinkers of all time.
The Oracle of Omaha
Taught Brian to focus on business quality and wide moats. Buy great companies at reasonable prices.
Co-Founder, Motley Fool
Taught Brian to seek optionality and big market opportunity. Find tomorrow's winners early.
Author, Antifragile
Taught Brian the importance of skin in the game and avoiding concentration risk. The best companies gain from chaos.
Brian combined these principles into one framework: antifragile investing. He seeks out companies that get stronger when everything else breaks. Then he buys them at a reasonable price.
His Antifragile Universe is a curated list of stocks that meet all of these traits. It's why he's outperformed. He's fishing from a stocked pond. When you join, you get full access to it.
Compounding Cash Flow
Companies that produce cash control their future
Founder-Led
Operators with skin in the game running the show
Durable Moat
Lasting competitive advantages that compound over time
Optionality
Multiple ways to win, not dependent on one outcome
Reasonable Price
Quality at the right price, never overpaying for growth
Strong Balance Sheet
Cash-rich, low debt, built to last
Nassim Taleb taught Brian that the most important signal of trust is when someone puts their own money on the line. Brian took that lesson to heart.
90% of Brian's net worth is in the same stocks you'll see inside Stock Investing Mentor. Not a paper portfolio. Not hypothetical picks. Real money. If he tells you a stock is one of his Top 5, he already owns it. If the stock drops, his net worth drops. If a pick turns out to be wrong, he loses more than you do.
That's the difference between a newsletter writer and a mentor who invests alongside you. Brian doesn't just teach Taleb's principle. He lives it.
12+ years of market-beating returns. No paper trading. Including the 2022 drawdown.
As of 1/1/26. Past performance does not guarantee future results.
For most of the 2010s, interest rates were near zero. In that environment, paying premium prices for high-growth companies was the right call. Money was cheap, future cash flows were valuable, and valuation discipline often hurt your returns.
Then inflation spiked. Interest rates rose. The math flipped.
In 2022, my portfolio dropped 53%. I held too many high-multiple growth names that compressed when the cost of capital changed. The valuation discipline I had been teaching was not strict enough in my own portfolio.
I rebuilt.
Today, valuation is a primary input to every buy, sell, and hold decision I make. It's not the only input, but it's no longer optional. I also learned that technical analysis, something I used to dismiss entirely, is actually useful. Not for picking stocks, but for reading the mood of the market. When valuations are collapsing, technicals can help you avoid catastrophic mistakes by showing you when sentiment has turned against a position. It's also the core ranking input behind Stoffel's Top 5: every stock in the Antifragile Universe is scored on valuation every 5 weeks, and the strongest opportunities rise to the top.
Members watched me make this transition in real time. The post-2022 framework is what's now in the live training, the Top 5 methodology, and every position write-up.
Growth-first analysis
Concentrated in high-multiple names
"Quality at any price"
Valuation as secondary check
Technical analysis dismissed
Growth + valuation discipline
Position sizing caps by theme
"Quality at the right price"
Valuation as primary input
Technicals used to read market mood
“Brian is honest and transparent in his views, a trait which is rare. That's what a mentee looks for.”

Brian Stoffel is a trained educator. Before investing, he spent years as a classroom teacher. That background taught him what actually makes complex ideas stick.
Most stock services hand you a list of tickers and say "buy these." But when the market drops 30%, you have no idea why you own what you own. You panic. You sell.
Brian is a teacher at heart. His training and years in education taught him what works and what doesn't when it comes to helping people learn. His goal isn't to build a following of copycats. It's to teach you to fish. He does this the only way that actually works: by putting his own money on the line.
Brian teaches using his real portfolio. He shares his stock picks, the lessons he's learned, his favorite ideas, and the framework behind every decision. You see everything. The wins, the losses, the struggles, the reasoning. Nothing is hidden.
Because he believes what he's teaching, 90% of his net worth is invested in the same stocks he shares with members. When he's wrong, he loses more than you do. That's a level of alignment you won't find anywhere.
But learning is best done in community. That's why the group meets weekly for live training and Q&A. And once a year, everyone gathers in person in Orlando. You're not just following a portfolio. You're joining a room of 500+ serious investors who are all building the same skill.
Teach you to fish
Build the skill to manage your own portfolio with confidence
Real money on the line
90% of Brian's net worth is in the same stocks he teaches
Learn in community
Weekly live sessions plus an annual in-person meetup
Most investors start with one of these two paths. Here is how Stock Investing Mentor compares.
You piece it together yourself. SEC filings, spreadsheets, guesswork on valuation. No feedback loop and no way to know if you're on the right track.
YouTube, Reddit, podcasts. Great for getting started, but scattered. No structure, no accountability, no way to know if the person talking has real skin in the game.
A complete system. Portfolio access, Top 5 every 5 weeks, live training, community, and a mentor with 90% of his net worth in the same stocks he teaches.
