The All-Weather Investor | Building a $5M portfolio—$1M already achieved | Sharing everything I learn along the way

Strategic stock investing for Wealth Managers and Family Offices.

Wealth preservation is essential. 

But true financial stewardship requires strategic growth—built on conviction, discipline, and risk management.

Many wealth managers and family offices struggle to find stock investment strategies that deliver superior returns without unnecessary complexity. Our approach bridges that gap.

I’m Marcello, a former doctor turned full-time investor with two decades of experience in stock and crypto markets. 

Since 2016, I have worked with wealth managers, family offices, and high-net-worth individuals to implement investment strategies that maximize performance while protecting capital.

In 2020 and 2021, my momentum-based approach transformed $32,000 into over $1 million. 

Today, we refine and apply that strategy for professionals seeking an edge in the markets.

What we offer: 

↳ Institutional-grade stock strategies designed for long-term performance
↳ Risk-managed investment frameworks to navigate uncertainty with confidence
↳ Tailored solutions for wealth managers and family offices seeking scalable, high-conviction strategies

Successful investing for superior returns focuses more on letting winners run and cutting losses quickly than on always predicting what will succeed, provided you're decent at spotting opportunities.

I love stocks with strong fundamentals, but I love them even more when there's a long-term tailwind pushing them forward.

AI is speeding up the markets, making trends shorter and more volatile with sharper swings. More than ever, you need to move quickly and not always hold out for a pullback before jumping into a new trade.

You need conviction in your strategy so you can handle volatility without doing dumb things. Conviction comes from knowledge + experience.

In most market environments, strong stocks perform extremely well. The exception is bear markets and liquidity crises, where hedging matters most. Otherwise, concentrate on stocks in strong phases. Right now, memory, fiber optics, gold miners, and commodities stand out.

Great managers are great at execution. It’s not only about picking good stocks, but also about position sizing, letting winners run, and cutting losses short. I would argue that execution is even more important than stock picking.

Strategies should be built on first principles. There is no single magic formula in fundamental or technical analysis. You need to understand the concepts that truly make sense and matter most (the 80/20 rule), and have the courage and discipline to execute.

Mental Resilience + Mindfulness for Corporate | Neuroscientist | WHO Fides Member

Hi! I’m Anne-Sophie 👋🏽, a neuroscientist.

Over the past 12 years, I’ve dedicated my career to understanding how the brain works and how we can leverage that knowledge to improve focus, resilience, and performance. With 6 years in academia and 6 years in industry, I’ve built a unique approach that combines cutting-edge neuroscience with practical strategies to help individuals and teams thrive.

I run mental fitness and performance workshops for organisations that want to invest in their people. My mission is to create workplaces where employees feel focused, motivated, and supported. 

Happy, resilient teams are the foundation of success.

It’s incredibly rewarding to see the transformation in teams I’ve worked with:

✨ Employees who feel inspired and equipped with tools to handle challenges
✨ Leaders who foster environments of productivity and innovation
✨ Organisations that experience measurable boosts in engagement and retention

I wasn’t always confident about bringing my expertise outside the lab. Like many academics, I worried about how to translate complex science into actionable advice. But over time working in health tech startups, I’ve honed my ability to connect the dots between research and real-world impact, delivering workshops that are both engaging and results-driven.

Here’s how it’s paid off:

Teams leave my workshops with strategies they can apply immediately.
I’ve had the privilege of working with high-performing teams across different industries.
My sessions consistently receive feedback about being inspiring, practical, and grounded in real science.

Now, I have two core missions in my work:

1️⃣ To empower individuals and teams with neuroscience-backed tools to be the best they can be- to improve focus, resilience, and performance.
2️⃣ To bridge the gap between academic research and actionable insights, making science accessible and impactful for organisations.

If you’re a leader or organisation looking to:
✔️ Boost team productivity and mental fitness
✔️ Reduce burnout and improve employee well-being
✔️ Cultivate a resilient, focused workforce

I’d love to help.

Here’s how we can work together:

1️⃣ Book a workshop
2️⃣ Connect with me for speaking opportunities
3️⃣ Follow along for weekly tips and insights, on LinkedIn and through my Newsletter

Another workshop with Wise 💸 💚 

We focused on mental resilience and how to use your brain intentionally to get the best out of it, both personally and professionally.

The results speak for themselves:
✅ 100% of participants said they now have a clear sense of vision and direction for their career at WISE (all rating this 4 or 5 out of 5).

 ✅ 80% said they feel supported by WISE to achieve both their personal and professional goals.

 ✅ 100% rated mental resilience as important or very important for personal and professional growth.

 ✅ 100% also said it’s important that WISE invests in programmes that support mental resilience and wellbeing- with most rating this as *very* important.

Beyond the numbers, participants shared that they left feeling:
More motivated
More reassured
More hopeful
Reconnected to what matters most
Een though it was a longer workshop, they said it felt easy to stay focused and involved.

There’s strong appetite to continue this work, particularly around:
 🧠 Focus
 😴 Sleep
 🧘 Mindfulness
 💪 Ongoing mental resilience support

Organisations that invest in mental resilience aren’t just supporting their employees wellbeing- they’re making sure their growth is sustainable, and protecting against absenteeism.

If you’re looking for someone to deliver practical, science-backed sessions on mental resilience and how to train your brain to perform at its best, I’d love to support your team.

Let’s talk.

A neuroscientist who will teach you hows to become mentally fit and emotionally resilient.

This weekend, I stepped out of my usual role - neuroscientist, meditation instructor, corporate facilitator - and became the participant.

I attended SHIFT, an immersive retreat concept by Camp Kerala designed around nervous system regulation, recovery, and presence. 

What struck me most wasn’t any single practice, but the conditions that were created, and even though the weekend was structured, it didn't feel at all rigid.

• Time without cognitive overload
• No constant task-switching
• Shared meals and deep conversations
• Structured rest and environments that contributed to learning

From a neuroscience perspective, this is exactly what allows the brain to move out of chronic threat mode and back into clarity, creativity, and regulation.

Even though I know this (and we all know this) it's incredible to experience and to witness. Sometimes we need to stop thinking/knowing and just do the thing.

What I'm taking away from this is to be a little less rigid with my own talks and workshops. Let people learn what they need to learn in that moment, rather than making sure they learn everything I want them to know.

Hi, I'm Anne-Sophie 👋  I help people understand their brains so that they can change how they think and feel. Follow for more neuroscience!

I love podcast mornings! Today I was filming for The Health Review Podcast 🎙️

I had a great conversation with journalist Emily Rose Adams about:

🧠 The latest in neuroscience
 ⚡ What “mental fitness” really means (and why it’s trainable)
 🤖 How AI is actively reshaping our brains
 🔁 How we can intentionally rewire our brains for focus, resilience, and high performance

Your brain is not fixed. It’s adaptive.

The same neuroplasticity that allows distraction, burnout, and digital overload to take hold… is the very mechanism we can use to build clarity, emotional regulation, and cognitive strength.

We also unpacked:
 • How constant AI assistance may be outsourcing critical thinking
 • What happens neurologically when we rely too heavily on tech
 • The practical tools individuals and teams can use to stay mentally sharp in an AI-driven world

If you’re leading a team or organization navigating rapid change and you're interested in bringing a neuroscience-backed mental fitness workshop or keynote to your team - my inbox is open.

Together we can build smarter humans, not just smarter systems. Come say hi!

I’m still smiling after yesterday's workshop I hosted for the Association for Coaching (AC)

Over 80 coaches signed up to talk about… sleep. One in 3 people suffer from regular sleep issues, so it's no surprise coaches need tools to support their clients.

Even for businesses, Sleep is a strategic topic. It underpins everything at work:

-Decision-making
-Emotional regulation
-Focus and productivity
-Communication and collaboration
-Resilience under pressure


When sleep suffers:

-Absenteeism increases
-Presenteeism rises
-Mistakes happen
-Conflict escalates
-Burnout risk grows

But when people understand sleep (and the neuroscience behind it), they feel empowered to make changes that will benefit them.

The feedback today mentioned:
✨ Insightful and thought-provoking
✨ Great pace and balance
✨ Evidence-based and engaging
✨ “2 hours flew by!”

This is why I love the work that I do. Translating science into practical, actionable strategies that help people think better, feel better and work better. Plus it's always a compliment when a two hour session ABOUT SCIENCE seems to fly by and gets an 100% EXCELLENT rating 👏 

With Sleep Awareness Week coming up in March, now is the perfect time to run a session for your team. If you’re planning your wellbeing calendar, let’s get something in the diary soon - March is already quite booked up!

If you’d like to bring a practical, science-backed sleep workshop to your organisation, message me or comment “SLEEP” and I’ll get in touch.

Here’s to better nights and better days. 🌙
