What is a portfolio?

A portfolio is the complete collection of everything you hold in an account, your available cash plus every open position in stocks, ETFs, or crypto. Its total value rises and falls as your holdings move. Spreading money across different positions, called diversification, is one common way traders manage a portfolio's overall risk.

Worked example

Your JagSim portfolio holds $40,000 in cash, $30,000 in one stock, and $30,000 in crypto, $100,000 total. If the stock climbs 10% (+$3,000) while crypto falls 5% (−$1,500), your portfolio is worth $101,500 even though one position lost money. That balancing act is why diversification matters. Because JagSim portfolios are permanent, you can watch yours grow over time.

Why it matters

Your portfolio is the full picture of what you're holding, cash plus every position, and its total value is what actually moves. It matters because one winning trade doesn't tell you much on its own; the portfolio shows how everything nets out together. It's also where diversification lives, spreading money across positions so a single bad move doesn't sink the whole thing. Because JagSim portfolios are permanent, watching yours evolve over weeks shows how your decisions add up. JagSim doesn't give buy or sell recommendations, price targets, or investment advice.

Common mistakes

Judging trades one at a time. A big loss on one position can be offset by gains elsewhere. Looking only at individual trades misses how the whole account is really doing.

Piling into a single name. When most of a portfolio sits in one stock or coin, that holding's swings dominate everything else. Heavy concentration is the opposite of diversification.

Forgetting that cash is part of it. Uninvested cash is still part of your portfolio. Ignoring it makes your real allocation look different from what it actually is.

FAQ

What counts as part of my portfolio?

Everything in the account: your available cash plus every open position in stocks, ETFs, or crypto. The total value is all of it combined.

What is diversification?

It's spreading money across different positions so no single holding drives the whole result. It's one common way traders try to manage a portfolio's overall risk.

Does my portfolio value change when I'm not trading?

Yes. As long as you hold open positions, their prices move with the market, so your total portfolio value rises and falls even when you aren't placing any orders.
