How to Invest in Stocks
Open a brokerage account, buy low-cost index funds, set up automatic monthly investing, and hold on when the market drops.
Investing sounds intimidating because the loudest voices, day traders showing off their screens and crypto influencers promising returns, make it sound complicated.
The approach that builds wealth over decades is simpler and more boring. It comes down to buying diversified funds, contributing regularly, and leaving the money alone.
You will end up with a brokerage account, an automatic monthly investment in low-cost index funds, and a plan for what to do when the market drops. We skip the jargon that does not help you act.
Money you will not need for at least 5 years. An emergency fund already in place covering 3 to 6 months of expenses. A phone or computer to open a brokerage account (takes about 10 minutes). Your Social Security number and bank account information for transfers.
Open a brokerage account
Fidelity, Schwab, and Vanguard are three large, long-established brokerages that suit beginners. They charge no account minimums, no trading commissions on stocks and ETFs, and have straightforward interfaces. The sign-up process takes about 10 minutes and is similar to opening an online bank account. You will need your name, address, Social Security number, employment information, and a linked bank account for transfers. All three brokerages offer both taxable accounts and retirement accounts (IRAs). You can open both. We will cover which type to use in a later step.
Understand what index funds are and why they win
An index fund is a collection of stocks that mirrors a market index. Instead of picking individual companies, you own a small piece of hundreds or thousands of companies at once. An S&P 500 index fund, for example, holds stock in around 500 of the largest US companies. If the overall market goes up, your fund goes up. This diversification protects you from any single company tanking. The performance data is clear. Over long horizons, the large majority of actively managed funds fail to beat their benchmark once fees come out. If you would rather check than take our word for it, look up the S&P SPIVA scorecard, which compares active funds against their indexes and is published twice a year. Actively managed funds charge higher fees, trade more often, and usually deliver worse returns after those fees. Warren Buffett made the same case in his 1996 letter to Berkshire Hathaway shareholders, writing that most investors will find the best way to own common stocks is through an index fund that charges minimal fees.
Good to know: Look for funds with expense ratios below 0.10%. This means you pay less than $1 per year in fees for every $1,000 invested. VTI (Vanguard Total Stock Market), VOO (Vanguard S&P 500), and FXAIX (Fidelity 500 Index) all have expense ratios of 0.03% or lower. A fee is charged every year on your whole balance, so over decades the difference between funds compounds too.
Choose the right account type
If your employer offers a 401(k) with a match, contribute at least enough to get the full match. That match is an immediate 50% or 100% return on your money. After maximizing the match, open a Roth IRA. In a Roth IRA, you invest money that has already been taxed, and qualified withdrawals in retirement are tax-free. Qualified generally means you are at least 59½ and the account has been open for 5 years, so check the rules before taking money out early. The contribution limit is $7,500 per year for 2026, or $8,600 if you are 50 or older, and that limit covers all your IRAs together. Roth IRAs also have an income limit. If you are under it and can afford to, max it out. After the Roth IRA is maxed, put additional money back into the 401(k) or a taxable brokerage account. Fill them in this order: employer match, Roth IRA, remaining 401(k) space, then a taxable account.
Set up automatic monthly investments
Decide on an amount you can invest every month without causing financial stress. Even $50 or $100 per month matters enormously over time thanks to compound growth. At a 7% average annual return, the same assumption the closing uses, $100 a month grows to roughly $122,000 over 30 years. You put in $36,000 of that. Set up an automatic transfer from your bank to your brokerage on the same day each month, ideally right after payday. Then set up automatic purchases of your chosen index fund. This strategy is called dollar-cost averaging. You buy more shares when prices are low and fewer when prices are high, which averages out your purchase price over time without requiring you to time the market.
Build a simple portfolio
For beginners, a two or three fund portfolio is all you need. A common approach is 80% US total stock market index fund (like VTI) and 20% international stock market index fund (like VXUS). If you want slightly less volatility, add a bond index fund (like BND) at 10 to 20% and reduce the stock percentage accordingly. Younger investors (20s and 30s) can be nearly 100% stocks because they have decades to recover from downturns. As you approach retirement age, gradually increase bonds. You will also see the older "age in bonds" rule quoted, where a 30-year-old holds 30% bonds. That is considerably more conservative than the 10 to 20% above, so treat the two as the ends of a reasonable range and pick the one that matches how you actually behave when the market falls.
Do not panic sell during market drops
Big drops are part of owning stocks. Hartford Funds counts 27 bear markets in the S&P 500 since 1928, drops of 20% or more, which works out to about one every 3.5 years over the whole period and one every 5 years or so since 1945. Smaller drops of 10% come more often than that. These are normal, expected events. What does lasting damage is selling during a drop out of fear. Every major decline in the US market so far has been followed by recovery and new highs, which is the historical record rather than a promise about the next one. Selling during a downturn locks in your losses permanently. Keep your automatic investments running through a downturn, because they buy more shares while prices are low. If watching your portfolio drop makes you anxious, check it monthly or quarterly instead of daily.
Heads up: Never invest money you will need within the next 5 years. Hartford Funds puts the average bear-market loss at 35%, and in the worst cases getting back to the previous high has taken years. Money for a house down payment, wedding, or emergency fund should be in a high-yield savings account, not stocks.
Open the account this week, set up the automatic monthly investment, and choose your fund mix from step 5. Once a year, check whether that mix has drifted from your target and rebalance if it has. When the market drops, leave it alone. Starting early costs nothing extra. Someone investing $200 a month from age 25 puts in $96,000 by 65. Someone starting at 35 and investing $400 a month puts in $144,000. At a 7% return the early starter still finishes ahead, roughly $525,000 against $488,000, on $48,000 less contributed. At lower returns that gap narrows and can reverse, so this is an argument for starting early rather than a guarantee. Start now, even if small.
Questions we get asked about this
Answers from experience, not a textbook.
Fidelity, Schwab, and Vanguard have no minimum to open an account. Fidelity and Schwab allow fractional share purchases, meaning you can buy $10 worth of a fund that costs $400 per share. Vanguard mutual funds have minimums (usually $1,000 to $3,000 for the first purchase) but their ETF equivalents have no minimum beyond the cost of one share. Practically, you can start investing with as little as $1. Set up the automatic monthly investment in step 4 at whatever amount you can keep up.
As a beginner, no. Stock picking requires significant research, conviction, and tolerance for being wrong. Even most professional fund managers fall behind the index over long periods, which is what the SPIVA scorecard in step 2 tracks. If you eventually want to pick individual stocks for fun, limit it to 5 to 10% of your total portfolio. Think of it as entertainment money. Keep the rest in index funds.
Crypto is speculative and extremely volatile. It has no underlying earnings, dividends, or intrinsic value beyond what the next buyer will pay. If you want exposure, treat it like high-risk entertainment money and limit it to 1 to 5% of your portfolio. Never invest crypto money you cannot afford to lose entirely. Build a solid stock and bond portfolio first, and only then consider speculative assets.
For practical purposes as a beginner, almost nothing. Both are baskets of stocks you can buy. ETFs trade throughout the day like stocks and cost one share to buy, or less at brokerages that sell fractional shares. Mutual funds trade once daily at market close and often have minimum initial investments. ETFs tend to be slightly more tax-efficient in taxable accounts. Inside a retirement account (IRA, 401(k)), the difference is negligible. Both work well. Use whichever your brokerage makes easiest.
Ideally, not until you need the money for its intended purpose (retirement, major life purchase). Selling triggers taxes on gains in taxable accounts and restarts the compound growth clock. Valid reasons to sell include rebalancing your portfolio back to target percentages, needing money for a planned expense, or shifting to more conservative allocations as you approach retirement. Invalid reasons to sell include a market drop, scary news, or a social media post recommending a different stock.
