Investing Basics

Master the fundamentals that drive long-term results: what investing is, how risk and return work together, why diversification matters, how compound interest grows your money, and how to build a simple asset allocation plan.

Overview: a simple path for beginners

Investing is the process of putting money to work so it can grow faster than cash over time. Instead of trying to “beat the market,” most successful investors follow a quieter playbook: diversify broadly, keep costs low, contribute regularly, and stay invested through market ups and downs.

This Investing Basics section is your starting point. Read each guide in order, or jump straight to the concept you need right now. Throughout the series, we link to deeper articles in Risk & Return and core ETF guides like ETF Basics.

Investing basics: quick FAQ

What are the basics of investing?

At a minimum, you should understand: what investing is, how risk and return are linked, why diversification reduces risk, how compound interest works, and how to pick an asset allocation that fits your goals and time horizon. The guides above walk through each of these ideas in detail.

How do I start investing with a small amount of money?

Begin by setting aside a small emergency fund and paying down high-interest debt. Then open a low-cost brokerage or investing account, choose a diversified fund or ETF, and set up an automatic monthly contribution. Consistency matters more than the starting dollar amount.

How much risk should a beginner take?

The right level of risk depends on your time horizon and how you react to market drops. If you have many years before you need the money, you can usually hold more stocks. If you are close to using the money or lose sleep during downturns, include more bonds and cash-like assets. Our Risk & Return and Asset Allocation guides go deeper.
