What Is Day Trading?
Day trading means buying and selling stocks within the same trading day. Learn how it works, why most day traders lose money, and the pattern day trader rule.
Definition
Day trading is the practice of buying and selling securities within the same trading day, closing all positions before the market closes. Day traders try to profit from small intraday price movements, often making dozens or hundreds of trades per day. They use technical analysis, chart patterns, and real-time news to make rapid decisions.
The SEC's Pattern Day Trader (PDT) rule requires that anyone making four or more day trades within five business days in a margin account maintain a minimum balance of $25,000. Below that threshold, your account may be restricted. This rule exists specifically because regulators recognize the extreme risk of day trading.
Study after study shows that the vast majority of day traders lose money. Research from the University of California found that only about 1% of day traders are consistently profitable. Most lose their starting capital within months. The few who succeed typically treat it as a full-time profession with years of training, sophisticated tools, and strict risk management.
Real-World Example
A day trader notices a stock gapping up 5% at market open on high volume. She buys 1,000 shares at $50.20, sets a stop-loss at $49.80, and watches for the price to reach $51.00. Twenty minutes later, the stock hits $51.10. She sells for a profit of $0.90 per share ($900 before commissions). This sounds great -- until you consider the six other trades that day where she lost $200-$500 each. After commissions and taxes (short-term capital gains), her net profit for the day is $50.
Why It Matters
Day trading is often marketed as a path to financial freedom, but the data tells a different story. Most people who try day trading end up worse off than if they had simply invested in an index fund and gone for a walk. If you are considering day trading, start with paper trading (simulated trades), understand the PDT rule, and never risk money you cannot afford to lose. For most people, long-term investing beats day trading -- it is boring, but boring tends to be profitable.

Frequently Asked Questions
Do most day traders make money?
No. Research consistently shows that 70-90% of day traders lose money. Only about 1% are consistently profitable over multi-year periods. The odds are heavily stacked against retail day traders.
What is the Pattern Day Trader rule?
The PDT rule requires a minimum account balance of $25,000 to make four or more day trades within five business days in a margin account. It applies to stocks and options. Accounts below this threshold are restricted.
How much money do I need to start day trading?
Technically, you can start with any amount, but you will be limited to three day trades per five business days unless you maintain $25,000+. Most professional day traders recommend starting with at least $25,000-$50,000.
Are day trading profits taxed differently?
Yes. Day trading profits are taxed as short-term capital gains (your ordinary income tax rate), which can be 22-37% for most traders. Long-term investors holding for over a year pay the lower long-term capital gains rate (0-20%).
