How much should I invest each month?

There’s no perfect number. Automate an amount that fits your budget after essentials and an emergency fund, then raise it when your income grows. Some investors work toward saving 15–20% of income for the long term.

Do I need to pick stocks?

No. Broad index funds through low-cost ETFs are a simple way to own hundreds or thousands of companies at once. Many long-term investors never pick individual stocks at all.

When should I rebalance?

Many investors rebalance annually or when their target mix drifts by 5–10 percentage points. Write a simple rule down in advance and follow it.

Start with the Basics

Three long guides that cover the basics before you move on to narrower topics.

Investing 101

A beginner’s guide to compounding, risk and return, building a portfolio, and investing your first $1k to $100k.

Asset Allocation Basics

How to think about a stock and bond mix for your goals, with sample mixes and simple rebalancing rules.

Investing Doesn’t Have to Be Complicated

Most investors don’t need complex products or to watch the market all day. Over long periods, the things you control are your asset allocation, your costs, how regularly you contribute and whether you stick with your plan. The guides focus on those.

Learn the building blocks in Basics, understand diversification with ETFs, and choose an approach in Strategies that fits your goals and temperament.
