GUIDE
A penny stock is a low-priced share, generally under $5, of a company trading off the major exchanges, and most day traders use the term for any thin name under $5, listed or not. Before you trade one, find out where it trades, what the spread costs in percent, and whether the company can sell more stock into the run.

Check where a stock trades before you check what it costs.
Under the SEC's penny stock rule, the term generally covers a stock priced under $5 that is not listed on a qualifying national exchange, from a company without enough assets or revenue to be excluded. So a $0.60 stock on Nasdaq generally falls outside the legal definition, even though every trader on the desk calls it a penny stock.
The split matters at the open because the two kinds of stock come with different information.
Then forget the price. A low price is a fact about share count, not about value. A $0.40 stock with 500 million shares is a $200 million company. A $12 stock with 2 million shares is a $24 million company. The cheap one is worth more than eight times as much.
Before your next trade in a low-priced name, write down the venue, the market cap and the float. If you cannot name all three, you do not know yet what you are trading.
It is 9:12 and a ticker is up 180% premarket. You have eighteen minutes, so run the same six checks every morning, in the same order.
Two blanks and the name comes off today's list. A ticker and a price is not a plan, and a name you could not finish checking by the bell will be replaced by another one tomorrow.
Keep the six answers beside each name in one line. By Friday you will have a record of which kinds of low-priced stock you read well, and that record is worth more than any list a stranger sends you.
Read the bottom of the pitch first. A line saying the writer was "compensated by a third party" means someone paid for your attention, and that someone usually has shares to sell.
A pump runs in four stages:
The only question you control is which stage you are buying into. Buy near the highs after the blast and you are the late buyer the early holders needed.
Three more tells show up on the tape.
Betting against it is not the easy answer. Shorting an obvious pump can bury you, because the squeeze can run further than you can survive and the borrow is often scarce and expensive.
There is also a way to lose the exit entirely. Between September 26 and October 22, 2025, the SEC suspended trading in nine Nasdaq-listed companies over suspected social-media schemes to inflate price and volume. When those suspensions ended, Nasdaq kept the stocks halted until the companies answered its requests for information. Before you buy a name running on a group chat, ask what the trade looks like if you cannot sell for a month. Sitting that one out is a good result.
Count every low-priced trade in percent, because cents will lie to you.
A penny of spread sounds like nothing. On a $50 stock it is 0.02%. On a $0.50 stock it is 2%, so if you buy at the offer and sell at the bid with no change in price, you are down 2% before the stock has done anything.
Per-share commissions stack on top. If your broker charges half a cent a share, that is 1% of a $0.50 price going in and 1% coming out. On a $100 stock the same half cent barely registers. Check your own fee schedule tonight, then do this arithmetic once. It changes which trades look worth taking.
Under a dollar, quotes can run to four decimals, so another order can step ahead of yours for a hundredth of a cent. Slippage comes next. When your order is bigger than the shares resting at the quote, it walks through the book and your average fill lands worse than where you clicked.
Four rules cover most of it.
A company that needs cash sees your breakout as a financing window. That is why good news on a low-priced name can rip 60% and bleed lower all day on heavy volume.
New supply arrives in a few recognizable shapes.

Before the bell, type the ticker into Dilution Check. It reads the company's SEC filings and returns a supply risk from low to high, then answers three questions: is a selling channel open, how many stock sales landed in the last twelve months, and how long does the cash last? Each form code links to its filing, so you can read the source yourself. A low reading describes what is on file and says nothing about where the stock goes next.
Under a dollar, a Nasdaq company is also on a clock. A closing bid below $1 for 30 straight trading days brings a deficiency notice and 180 calendar days to fix it, sometimes with a second 180. A company that did a reverse split in the prior year gets no automatic 180 days. And since January 19, 2026, a closing bid at or below $0.10 for ten straight trading days brings an immediate suspension.
The fix is usually a reverse split or a raise, and the tape tends to sell both. Before you trust a bounce near a dollar, look through the company's filings for an 8-K with Item 3.01, where these notices get reported.
Every expensive mistake on a low-priced runner gets made in a few seconds: the chase, the re-entry after a loss, the stop you drag because you are sure it comes back.

So write your rules tonight, each one answerable yes or no.
MAKETZO is a trading discipline system for small cap day traders, built on one idea: you set the rules while you are calm, and it enforces them when you are not.
If you execute on DAS Trader, your trades can be imported from there. It is the only import MAKETZO takes, and a net P&L you type by hand works for the accountability side. MAKETZO never tells you what to buy, and it gives no stock picks or financial advice. Every plan starts with a 7-day free trial, and MAKETZO's pricing page lists the plans.
Any list that answers that goes stale within hours, because float, spread and filings keep changing, and a low price says nothing about quality. MAKETZO gives no stock picks. Treat a ready-made list as a place to start your checks: find out who wrote it and whether anyone paid for it, then run each ticker for venue, float, catalyst, spread in percent and supply. A name that clears all of them is worth watching, and whether it is worth trading is your call.
Some traders do, and a low price does nothing to improve the odds. Costs run higher in percent, supply can appear in the middle of a run, and a halted stock cannot be sold. Answer it with your own record: take your last 30 sessions in low-priced names and compare your average win with your average loss after spread and commissions, then count how many of the losses came on days you broke a written rule. If the math does not work there, a lower price will not fix it.
Under $5 is the line most U.S. traders use, and the SEC rule uses the same figure, while many names trade under $1. The price alone will mislead you, because a stock under $5 can be a far larger company than one at $12, and a low-priced name on Nasdaq generally falls outside the legal definition. Use the price band to estimate your costs: the lower the price, the more a penny of spread costs you in percent.
