I'm Elad Nahum — a technical founder who spent 17 years managing real portfolios and a decade shipping production software. I put both to work building Guardfolio: institutional-grade portfolio risk, made usable for everyday investors. Here I write about markets, risk, AI, and what it actually takes to build financial software that works.
Everything I learned managing portfolios for 17 years, built into software. Guardfolio connects your stocks, crypto, and ETFs, scores your real risk, and alerts you before something breaks — the kind of monitoring desk that used to be reserved for institutions.
One number that captures your portfolio's real risk, updated as markets move.
Plain-language warnings before market, position, or event risk turns into a loss.
Every account — stocks, crypto, and ETFs — in one risk-aware view.
Concentration, correlation, and exposure analysis that used to need a terminal.
I began in portfolio management at Bank Hapoalim, where years advising clients taught me how risk feels in real life — not just how it looks in a model.
I later earned an MBA and taught myself to code. After shipping full-stack products at CHEQ, I founded Guardfolio to bring institutional-grade risk tools to individual investors.
A few of the teams and experiences behind what I'm building now.
Full-stack engineering on the product-led growth team at a global ad-tech company. Architected and shipped features used by enterprise clients worldwide — Vue.js frontends, Golang microservices, and everything in between. Turned product strategy into measurable revenue.
Started my career advising clients on portfolio allocation across equities, bonds, and structured products. Real money, real consequences — the foundation that informs every product decision I make today.
Essays on portfolio risk, markets, AI, and what it actually takes to build at the intersection of finance and software.
AI stocks are powering market gains, but ETF overlap, Nvidia concentration, high valuations, and leverage can leave portfolios less diversified than they appear.
Different ETF labels can still point to the same underlying stocks, creating hidden concentration risk in AI-heavy portfolios.
Volatility is not the enemy. Mismanaging it is. Here are the strategies that actually work when markets get choppy.
Most portfolios are far less diversified than their owners think. Here's what concentration risk really looks like, and why it's so easy to miss.
The domains I write, build, and think in — at the edge of markets, software, and what makes businesses actually work.
Right now: Building Guardfolio, writing about markets and risk, exploring AI in portfolio management.
Whether you're working on something interesting, want to explore a partnership, or just want to talk markets and building — I'm open to conversations that go somewhere.
