Investment Fundamentals: A Beginner’s Guide to the U.S. Market
Starting to invest can feel confusing, especially if you are new to the U.S. market. Many people worry about picking the right investment or understanding risk. This guide explains the basics of investing, common terms, and the main options available, helping you feel more comfortable when exploring your choices. Remember, all investments carry risk and understanding them is the first step to making informed decisions.
Understanding Investment Basics
Investing means purchasing assets with the expectation that they'll increase in value over time. This means accepting some level of risk in exchange for potentially higher returns. You can have lower risk investments, which tend to yield lower returns, and you can also have higher risk investments, which tend to yield higher returns. This is different from saving, which means preserving your money's current value while prioritizing safety and immediate access.
Some key concepts for beginners:
- Risk tolerance: How much uncertainty you can handle in your investments. This helps determine an appropriate investment strategy by balancing potential gains against the risk of loss.
- Diversification: Spreading investments across different assets to reduce potential losses.
- Time horizon: How long you plan to invest. If you need that money to pay rent at the end of the month, your time horizon is short term. If you can live without that money and keep it invested over the next 20 years, your time horizon is long term.
It’s important to know that investing has no guarantees. Unlike bank accounts, most investment accounts are not FDIC insured. Inter, however, is a member of the FDIC, which means deposits in eligible bank accounts are insured up to the applicable limits. Some investment accounts are SIPC protected, which can help if a brokerage fails, but this protection does not cover market losses.
Investment Options Available in the U.S. Market
The U.S. market offers you a wide range of investment choices designed to fit different goals, time horizons, and levels of risk tolerance.
Whether you prefer to manage your own portfolio, invest through diversified funds, or keep your money in lower-risk alternatives, understanding how each type works can help you make more informed decisions.
The table below summarizes the main characteristics of the most common investment options available in the U.S. — from individual securities to more conservative alternatives.
