Investing in U.S. Stocks: A Beginner's Guide (Nvidia, Apple, Tesla & More)

Owning shares in companies like Nvidia, Apple, or Tesla is more accessible than most beginners think — you can start with a few dollars. This guide explains, in plain English, how it actually works, how to begin, and the one tax detail that catches non-residents off guard.

What a Stock Actually Is

A share of stock is a small piece of ownership in a real company. If the company grows and becomes more valuable, your share can be worth more; some companies also pay you a slice of profits called a dividend. You make money two ways: the price going up over time (capital gains) and dividends.

The Companies Everyone Asks About

These are all publicly traded — you can buy them through any brokerage using their ticker symbol:

Nvidia (NVDA) — chips powering the AI boom
Apple (AAPL) — consumer hardware and services
Microsoft (MSFT) — software and cloud
Alphabet / Google (GOOGL) — search, ads, and cloud
Tesla (TSLA) — EVs and energy

What about SpaceX? SpaceX is privately held — it is not listed on any stock exchange, so you cannot simply buy its shares in a normal brokerage. Retail access is limited to occasional secondary markets or funds that hold a stake, usually for accredited investors. Be cautious of anyone "selling SpaceX stock" directly.

How a Beginner Actually Starts

Open an account with a reputable brokerage (many accept non-U.S. residents; you will complete a W-8BEN to certify foreign status).
Fund it and decide how much you can comfortably invest for the long term.
Buy whole or fractional shares — fractional lets you own part of an expensive stock with a small amount.

Don't Bet Everything on One Stock

Putting all your money into a single company is risky, even a great one. Most beginners are better served by diversifying — spreading money across many companies. The simplest way is a low-cost index fund or ETF (for example, one tracking the S&P 500), which holds hundreds of large U.S. companies — Nvidia, Apple, Microsoft, and the rest — in a single purchase.

The Tax Part — Important for Non-Residents

This is where SK Financial's clients are often surprised:

Capital gains: a nonresident alien is generally not taxed by the U.S. on profits from selling U.S. stock (assuming you are not in the U.S. 183+ days and the gain is not effectively connected income).
Dividends: U.S. dividends paid to a non-resident are subject to 30% withholding, which a tax treaty can reduce to 15% or less — claimed via your W-8BEN.
Estate tax trap: U.S. stocks are U.S.-situated assets and can be exposed to U.S. estate tax for non-residents above a low ($60,000) threshold — worth planning around for larger holdings.

Beginner Principles

Invest for the long term — years, not days.
Only invest money you will not need soon; prices fall as well as rise.
Keep costs low and avoid hype, "guaranteed" tips, and pressure to act fast.

This guide is general education, not investment advice. Investing carries risk, including loss of principal. Consider speaking with a licensed financial advisor before investing.
