Growth investing

In short

A friend of mine once told me he bought a stock because everyone at the barbershop was talking about it. He never asked what the company earned. Growth investing asks that question first. It is a way of choosing companies that you expect to grow sales and profits faster than the rest of the market. You can act on this in a few plain steps. Start by writing down why you think a company will keep growing, in one or two honest sentences. Check what you would pay for each dollar of earnings before you pay it. Decide how much of your money you can leave alone for many years. Learn what the fund charges you each year, because that cost never takes a day off. Put your retirement dollars in the right account first, since $7,500 for 2026 (source, checked 10/4/2026) is the yearly cap on an IRA and you will want to know your room.

The whole of it

What it is

You have probably heard someone say, "Buy what you know." There is some sense in it, but growth investing goes a step further. It looks for companies whose sales and profits are rising quickly, and it accepts that you may pay a higher price for them. The idea is simple. If the business keeps growing, its value may grow with it. If it stops growing, the price you paid can shrink fast.

I once watched a neighbor plant an oak tree and a row of tomatoes on the same spring day. The tomatoes gave him supper by August. The oak gave him nothing for years. Growth companies are a little like that oak, but with a catch. Some of them turn out to be tomatoes wearing an oak costume.

The other side of the coin is value investing. A value investor looks for companies that seem cheap compared to what they earn now. A growth investor looks for companies that may earn much more later. Neither way is wrong. They are just two ways of asking what a business is worth. You may hold funds that do both, and there is no shame in that.

How it works

If you are holding a growth fund or a single stock, you own a small piece of a company. The company keeps most of its profit and puts it back into the business. It hires people, builds things, and buys equipment. That is why many growth companies pay little or nothing in dividends. A dividend is a share of profit paid out to owners. Growth companies would rather use that cash to grow.

So where does your return come from? Mostly from the price going up. You buy a share at one price and hope to sell at a higher one. That means your result depends on other buyers agreeing later that the company is worth more. This is why growth stocks can swing hard. When people feel good, prices climb. When people worry, prices can drop even if the business itself is fine.

Taxes matter here too. If you hold a stock in a regular account and sell it for a gain, you may owe tax on that gain. How much depends on how long you held it and on your income. The IRS explains this on its page about capital gains and losses, and in Publication 550, Investment Income and Expenses. In an IRA or a 401k, the tax rules work differently, and you generally do not pay tax on each sale inside the account. Your plan documents and the IRS pages spell out the details.

One more piece is worth knowing. A common way to size up a growth stock is the price to earnings ratio. That is the share price divided by the profit the company earned per share over a year. A high ratio means you pay a lot for each dollar of profit today. Buyers who pay it are counting on that profit to rise.

The numbers, and where to find yours

I have found that people feel better once they see the actual figures for themselves. So here is where to look.

For yearly limits on retirement accounts, go to the IRS page on retirement plans and IRAs. The limit for an IRA is $7,500 for 2026 (source, checked 10/4/2026). The limit for a 401k employee deferral is the current figure, which the official source publishes each year. If you are older, there may be an extra catch up amount, and the age it starts is the current figure, which the official source publishes each year. The site fills in the verified figures with their source and date, so please trust those over anything you remember hearing at a cookout.

For fund costs, look at the expense ratio. That is the yearly fee, shown as a percent of your money. You will find it in the fund's prospectus, which is the official document that describes the fund. The SEC's Investor.gov site explains how fees add up over time. A fee that looks tiny can take a real bite over twenty years.

For a stock's own numbers, look at the company's annual report on Form 10 K, which it files with the SEC. You can search for it free on the SEC's EDGAR database. It shows sales, profit, and the risks the company itself worries about. That last part is worth reading slowly.

For your own tax rate on gains, use the IRS pages named above, and check your last return. Your rate depends on your situation, and only your own paperwork can tell you.

A worked example

Let me tell you about a woman named Marisol. She is 35 and earns 52,000 dollars a year. Her employer matches 3 percent of her pay in her 401k. She wants to put some money in a growth fund and wants to see what it costs her.

First, the match. Three percent of 52,000 is found by multiplying 52,000 by 0.03. That gives 1,560 dollars a year from her employer. Marisol decides that is free money worth taking, so she contributes at least 3 percent herself, which is also 1,560 dollars. Together, that is 3,120 dollars going in each year.

Now the fund fee. She is choosing between two growth funds. Fund A charges 0.10 percent a year. Fund B charges 0.90 percent a year. She imagines she has 20,000 dollars in the fund.

For Fund A, the yearly fee is 20,000 times 0.0010. That equals 20 dollars.

For Fund B, the yearly fee is 20,000 times 0.0090. That equals 180 dollars.

The gap is 180 minus 20, which is 160 dollars a year on that same balance. It does not sound like much. But it comes out every single year, whether the fund goes up or down. As her balance grows, the gap grows with it.

Marisol also looks at one stock she likes. It earned 2 dollars per share last year and trades at 60 dollars. She divides 60 by 2 and gets a price to earnings ratio of 30. She reads that as paying 30 dollars for each dollar of yearly profit. She decides she needs to understand why anyone would pay that. So she opens the company's 10 K and reads how fast its sales have grown and what risks it lists.

Notice what Marisol did not do. She did not chase a tip. She took the match first, checked the costs, and did her reading. Good habits.

Where it goes wrong

I have made mistakes in my own life, and I would sooner tell you about them than pretend otherwise. The biggest trap in growth investing is paying too much for a good story. A company can be wonderful and still be a poor purchase at a high price. If the ratio is very high, small bad news can hurt a lot.

Another trap is putting too much in one place. If you own a single stock and it stumbles, your whole plan stumbles with it. Spreading your money across many companies through a fund can soften that blow. It cannot remove it.

A third trap is losing patience. Growth investing asks you to sit still through some ugly stretches. Prices can fall for years before they rise. If you will need the money soon, this may not be the right home for it. That is a fact about time, not a fault in you.

Watch the fees, too, as Marisol did. And watch the taxes. Selling often in a regular account can leave you with a bill you did not expect. Slow and steady is a fine motto here.

Last, be careful with your own feelings. Fear tells people to sell at the bottom. Excitement tells them to buy at the top. Knowing that about yourself is half the battle.

Questions to answer before you leave this page

What is the money for, and when will you need it? Could you leave it alone through a long stretch when the price drops and stays low? Have you taken the full employer match, if you have one? Do you know the yearly fee on the fund you are eyeing, and what it comes to in dollars on your own balance? If you are looking at a single company, can you say in one plain sentence why it should keep growing? Have you looked at its price to earnings ratio and asked what has to go right to justify it? Is too much of your money riding on one company or one type of business? Do you know which account will hold this investment, and how gains in that account are taxed? And have you looked up the current limits at the IRS so that $7,500 for 2026 (source, checked 10/4/2026) and the current figure, which the official source publishes each year are numbers you know rather than numbers you guessed?
