Why diversify?

Watch risk shrink as you add holdings

Drag the slider to add stocks to an equal-weight portfolio. Volatility falls fast at first, then levels off. What remains is market risk, which no amount of diversification removes — which is why Pininvest scores every theme and portfolio on risk, not just return.

Illustration: each stock has 35% annual volatility and a 0.25 average correlation with the others.

Questions

Straight answers before you start

Want the details? The white paper explains Pininvest's key features and how its analytics are built.

Is Pininvest really free?

Yes. Pininvest is free for registered users, and most features will stay free for the community. Corporate licensees help cover our costs as the platform matures.

Do I need a brokerage account or real money?

No. Portfolios in Pininvest are virtual: you record orders and cash, and Pininvest tracks the results. Nothing is connected to a broker, so no real money ever moves.

What do “performance” and “risk” mean here?

Performance is the return over the period you select, from two weeks to one year. Risk is measured mainly as annualized volatility — how much returns swing — together with diversification. Pininvest shows them side by side because a strong return with extreme swings may not suit your goals.

Where does the data come from, and how fresh is it?

Prices and fundamentals come from established market-data providers, and themes, strategies and portfolios are refreshed every trading day.

Is this investment advice?

No. Pininvest provides data and tools to research and test your own ideas. Past performance does not guarantee future results, so do your own research before investing real money.

Is there a mobile app?

Yes. Pininvest is available on iOS and Android, so you can follow your themes and portfolios on the go.
