Chapter 01 · The why
Most platforms are built for speed.
Slowio is built for clarity.

Brokers scream at you to trade. Research portals drown you in tabs. Bloomberg-style terminals make you rent a throne to look at a spreadsheet.

Slowio does the opposite. Forty years of data, a clean page per idea, and a single question at the top of every screen — is this a good business at a fair price?

Chapter 02 · All in one place
Everything a value investor needs.
One tab.

Fundamentals over here, screening over there, correlations behind a paywall, a DCF inside a rotting Excel sheet. Most investors stitch their toolkit together from five or six products — paying for each, switching tabs between each.

Slowio collapses all of it into a single platform. At a fraction of the cost.

Chapter 06 · Correlations
The relationships hiding underneath your portfolio.

A portfolio is only as diversified as its cross-correlations say it is. Slowio lets you see those relationships as a matrix, a network, and a scatter — three ways of asking the same question.

Plot any two tickers, any two ETFs, any two indices. Trend line + R² + correlation in one glance — spot clusters, find outliers, confirm the numbers the matrix was whispering.

The goal isn't noise reduction. It's diversification you can actually defend.

Chapter 07 · Returns & volatility
Risk / Return

Two numbers
tell you most of the story.

Returns without volatility are a tease. Volatility without returns is a warning. Slowio computes both — for stocks, portfolios, and watchlists — and places them on the efficient frontier so you can see where you sit.

  • Total & annualised returns
  • Realised volatility & drawdowns
  • Sharpe & Sortino ratios
  • Rolling windows across 40+ years

Chapter 11 · What we believe
Three principles.
Everything else is a consequence.
01 / Depth

One good year
isn't enough.

A short-term chart looks like a recent trend. A multi-year chart shows you the cycle. We keep the long horizon because investors need context, not crops.

02 / Restraint

One screen,
one question.

Every page answers a single thing — "is this a good business?", "is it fairly priced?", "how does it sit in the book?" — not fourteen things at once.

03 / Fairness

Institutional data,
retail price.

Built to be 90% cheaper than the terminals it replaces, with a free plan that's genuinely usable — not a paywall in disguise.

Chapter 12 · The receipts
Quietly,

Chapter 13 · The builder
"

We built Slowio because we couldn't find a research tool that respected both our time and our wallet. It's a small team's work — quiet, efficient engineering — the kind of product you only get when someone is scratching their own itch.

Chapter 14 · Questions
The usual questions.
Answered.

The things people ask before signing up.

01 Slowio vs competitors — what's actually different? +

Four things. Depth: forty years of fundamentals, not ten. Restraint: one question per screen, not fourteen at once. Breadth: everything a value investor actually needs — financial analysis of annual reports, correlations, screening, alerts, portfolios, calculators — all in one place. Price: roughly 90% cheaper than the terminals it replaces, with a free plan that's actually usable.

The trade-off: no dedicated account manager, no trading-floor vibe. That's the point.

02 What happens if I do not renew Advanced or Premium? +

You drop back to the free tier. Your portfolios, watchlists and saved screenings stay where you left them. No card on file means no auto-rebill. If you want to leave completely, your data is exportable.

03 Why is it affordable? What's the catch? +

No venture capital, no sales team, no sponsored research, no CFA-on-call. The whole thing is one efficient, passionate team that uses Slowio for its own investments.

04 Which countries and asset classes are covered? +

Stocks and ETFs across 20+ markets including the US, Switzerland, UK, Germany, France, Italy, the Netherlands, Belgium, Canada and Japan. Plus government bond curves, sector aggregates and macro indicators.

No futures, no FX, no crypto, no intraday trading or short-term investing. If that's what you're looking for, Slowio is not the place.

05 How often is data refreshed? +

End-of-day prices daily (which is more than enough for long-term investing). Fundamentals and macro follow the publishing bodies. Intentionally not real-time — if you need tick-by-tick, this isn't the tool.

06 I'm not a value investor — is it still useful? +

Probably, yes. Fundamentals, portfolio tracking, screening, correlation analysis and the compound-growth calculator are methodology-agnostic. If you are looking for short-horizon, technical or derivatives-heavy strategies — that's not what it's built for.

07 Does Slowio hold my money or execute trades? +

Never. Slowio does not custody funds. Slowio does not place trades. Slowio does not connect to your broker. There is no "buy" button anywhere on the platform. You act elsewhere — on your own brokerage, at your own risk.

Slowio is an educational research tool. Not financial advice.

No money is held, managed, or transferred through Slowio. No trades are placed. Slowio does not connect to any brokerage account.

Slowio is a simple research and analysis platform. Every score and every chart is indicative and educational only — a way to ask better questions, not a recommendation. Do your own research.

All analysis is yours to interpret. All decisions — and all transactions — happen on your own brokerage, at your own risk.
