Penny stocks are shares of very small companies that trade at low prices. In the US, the SEC generally describes a penny stock as one that trades below $5 a share. Many trade on over-the-counter markets, where reporting rules can be lighter than on the big exchanges. They can move fast in both directions. That speed is the appeal, and it is also the danger. This guide explains how they work, what can go wrong, and how careful investors approach them.
Why penny stocks move so much
Small companies have fewer shares trading and fewer people buying and selling. A little demand can lift the price, and a little selling can drop it. A stock can jump 30 percent in a day on a press release and give it all back the next week.
Two things make this harder. Wide bid-ask spreads mean you can lose money just by entering and exiting. Thin volume means there may be few buyers when you want to sell. A price on the screen is not the same as a price you can actually get.
The main risks
Information can be limited. Some companies file full reports. Others share very little. Some have almost no revenue and fund themselves by selling new shares, which can shrink the value of the shares you already own. This is called dilution.
Promotion is also common. Paid newsletters, social media posts and email blasts can push a price up for a short time. When the promotion ends, the price often falls. Learn the red flags in stock promotions and how to spot a pump and dump. Under US rules, people paid to promote a stock must disclose that payment. If you cannot find who paid for what you are reading, treat it with caution.
What careful investors check first
They start with the filings. Does the company file regular reports with the SEC or with Canadian regulators on SEDAR+? Companies that stay current with filings give you more to work with. Next they check cash and debt on the balance sheet. A company with little cash and large short-term debt may need to raise money soon, often on bad terms.
Then they look at revenue. Is there any? Is it growing? Then the share count. Has it risen sharply over the last few years? Finally, they ask who owns the shares and who is selling them. Large holders selling into a spike can end a rally quickly.
Understand the size category
Penny stocks overlap with small, micro and nano caps. These groups have different risk levels. Read why small caps move and micro cap vs nano cap to see where a company sits.
Size small and set your loss first
Treat penny stocks as speculation. Many investors keep them to a small slice of their money, and they decide their loss limit before they buy. If you risk 1 percent of your account on a trade, a bad outcome costs you 1 percent, not half of your savings. The position size calculator turns your entry and stop into a number of shares. Read how to set a risk limit you can live with and see our risk management guide.
A pre-trade checklist
Does the company file reports with the SEC or SEDAR+? Does it have revenue, and is it growing? Is there enough cash for the next twelve months? Has the share count grown quickly? Who is promoting the stock, and were they paid? How wide is the spread, and how many shares trade a day? What will I do if it falls 20 percent? If you cannot answer these, wait.

Frequently asked questions
Are all penny stocks scams?
No. Many are real companies at an early stage. But the group has more fraud and more failure than larger companies, so extra care is needed.
Can I get rich from penny stocks?
A few stocks rise a lot, but most do not. Planning around the chance of a big win is risky. Plan around limiting your losses.
Where can I check a company’s filings?
US companies file on SEC EDGAR. Canadian companies file on SEDAR+. Read the annual report and the latest quarterly report.
What is the biggest warning sign?
Pressure to act fast, especially with promises of large, certain gains.

Two costs that do not show up on the chart
Take a stock with a bid of $0.10 and an ask of $0.12. If you buy at the ask and the price does not move, the most you could sell for right away is the bid. That is about 17 percent below what you paid. The spread works like a fee that you pay before the trade has a chance to work.
Dilution is the second cost. Say a company has 50 million shares and you own 1 million, or 2 percent. It sells 25 million new shares to raise cash. Now there are 75 million shares, and your 1 million shares are about 1.3 percent of the company. The price you paid did not change, but your slice got smaller. You can check how share count affects size with the market cap calculator.
Common mistakes with low priced shares
A low share price is not the same as a cheap company. A stock at $0.50 with 400 million shares has a market value of $200 million, which can be more than a $20 stock with 5 million shares. Another mistake is buying because a name is trending on social media. A third is placing a market order on a thin stock, which can fill far from the price you saw. A limit order sets the most you will pay.
What to do next
Pick one penny stock you have heard about and do not buy it. Instead, find its latest filing, write down cash, debt and the share count from three years ago and today. Then use the stock profit and loss calculator to see what a 50 percent drop would do to a small position. Unfamiliar words are explained in the glossary.
