Quick Answer
The best stocks to day trade are those with high liquidity (high volume) and volatility (significant daily price swings). These are typically large-cap tech stocks, index ETFs (like QQQ), or high-growth stocks with pending news. However, mastering how to daytrade requires navigating US regulations, specifically the Pattern Day Trader (PDT) Rule, which mandates a minimum account balance of $25,000 for frequent trading in margin accounts. Choosing the right platform—and understanding why platforms like Robinhood are often poor choices for serious, high-frequency traders—is key to survival.
🚀 The Core Strategy: Which Stocks to Day Trade?
The strategy for choosing stocks to day trade is diametrically opposed to long-term investing. Investors look for stability and low volatility; traders look for movement and high volatility.
The Trader’s Checklist: The “M&V” Rule
Day traders hunt for two primary characteristics:
Liquidity (High Volume): This ensures you can enter and exit trades instantly without your large order moving the price against you. High volume means there is always a buyer and seller available.
Metric to check: Stocks trading millions of shares daily.
Volatility (Daily Range): This provides the movement needed to generate profit. If a stock moves only $0.20 per day, the profit potential is too small.
Metric to check: A high ATR (Average True Range) indicator, showing the average daily price movement is substantial.

🛑 The Regulation: How to Daytrade Legally
Mastering how to daytrade is impossible without understanding the US accounts taxes & rules, especially the Pattern Day Trader (PDT) Rule.
What is the PDT Rule?
The PDT Rule, enforced by FINRA, restricts frequent trading in margin accounts to protect small, inexperienced accounts from the rapid destruction caused by leverage.
The Definition: Executing 4 or more day trades over a rolling five-business-day period. (A day trade is buying and selling the same security on the same day).
The Requirement: If you are flagged as a PDT, you must maintain a minimum account equity of $25,000.
The Penalty: Falling below the $25,000 threshold will result in your brokerage freezing your ability to day trade for 90 days.
Avoiding the PDT Rule for Small Accounts
If you have less than $25,000, your options are limited but possible:
Limit Trades: Restrict yourself to three or fewer day trades per five days.
Cash Account: Use a cash account instead of a margin account. The PDT rule does not apply, but you must wait one business day (T+1 settlement) for funds from a stock sale to settle before you can use the cash again. This severely limits trading frequency but keeps you compliant.
Futures/Forex: The PDT rule generally does not apply to these markets, which have their own (often higher) leverage and risk rules.
📱 Is Robinhood Good for Day Trading?
The question is Robinhood good for day trading is common for beginners, but the answer for serious traders is generally no.
Verdict: Robinhood is excellent for long-term investing and ease of use. However, the milliseconds lost on trade execution and the lack of professional tools mean a trader with a statistical edge will struggle to maintain profitability against faster, better-equipped competitors.
💡 How to Daytrade: The Professional Mindset
Successful day trading is a disciplined practice built on a statistical edge and strict risk management.
1. Risk Management (The 1% Rule)
Never risk more than 1% of your total account equity on any single trade. If you have $25,000, your maximum loss on any single trade is $250. This rule is non-negotiable for survival.
2. Technical Analysis
Day traders rely on tools to understand short-term market psychology:
VWAP (Volume Weighted Average Price): Used to gauge whether institutions are buying or selling throughout the day.
Support & Resistance: Key price levels where buying or selling pressure is expected to reverse the trend.
Candlesticks: Used to identify short-term momentum and indecision.
3. Strategy Execution
Define your R:R (Risk-to-Reward) ratio before you enter. You should only take trades where the potential profit is at least $\mathbf{2x}$ the maximum risk (e.g., risking $100 to make $200).
Tool Tip: Use the principles of the AI Portfolio Learning Tracker to meticulously record every trade, entry, exit, and the emotional reason behind it. Reviewing this data is how you build an edge.
🇺🇸 US Taxes: The Cost of Day Trading
Frequent trading increases tax complexity and liability significantly.
Short-Term Capital Gains: All profits from day trades are taxed at your ordinary income tax rate, which is higher than the long-term capital gains rate.
Wash Sales: Day traders frequently and accidentally violate the Wash Sale Rule, which prohibits claiming a loss if you buy the same security within 30 days before or after the sale. This often leads to massive, unexpected tax bills.
Action Step: You must seek a certified public accountant (CPA) who specializes in Trader Tax Status (TTS) to manage the thousands of transactions and complex tax filings.
Final Word From The Desk
Stocks to day trade are numerous, but the opportunity is only available to the disciplined and well-capitalized. Trading successfully requires superior tools and unflinching respect for the $25,000 PDT rule and the tax code. If you are starting small, focus on swing trading (holding overnight) or investing in education first.
