💬Get To Know Floats

Understanding stock floats and free floats is particularly crucial for day traders, who capitalize on short-term price movements. These concepts, while fundamental to all market participants, have specific implications for day trading strategies due to the direct impact on stock volatility and liquidity. Here's a breakdown tailored for day traders:

Introduction to Stock Market Dynamics for Day Traders

Day trading is the practice of buying and selling stocks within the same trading day. Success hinges on understanding how various factors, including stock floats and free floats, influence price volatility and trading volume.

What is a Stock Float?

The stock float refers to the total number of shares publicly available for trading. For day traders, the size of a stock's float is a critical factor because:

  • Low-float stocks (fewer shares available) can have more pronounced price movements on lower volume, presenting high reward (and risk) opportunities within short time frames.

  • High-float stocks (more shares available) tend to be more stable, requiring significant volume to move prices, which can be less attractive for short-term trading strategies.

The Significance of Stock Float for Day Trading

  • Volatility: Day traders often prefer trading low-float stocks due to their potential for rapid price changes, offering opportunities for quick profits.

  • Liquidity: While high-float stocks provide more liquidity, making it easier to enter and exit trades, the associated lower volatility may offer fewer opportunities for quick gains.

What is Free Float?

Free float is a subset of the stock float, representing the number of shares actually available for public trading without restrictions. It's a more precise measure for day traders as it directly correlates to the stock's liquidity and potential for price fluctuation.

Free Float vs. Total Shares Outstanding

  • Total Shares Outstanding includes all shares a company has issued, but not all are available for public trading.

  • Free Float excludes shares held by insiders, governments, and other locked-in investors, providing a clearer view of the market's available supply for trading.

Calculating Free Float for Day Trading Strategies

Free Float=Total Shares Outstanding−Restricted SharesFree Float=Total Shares Outstanding−Restricted Shares Understanding and calculating a stock's free float helps day traders identify stocks with the right balance of volatility and liquidity for their trading strategy.

Practical Implications for Day Traders

  • Strategy Adaptation: Adjusting trading strategies based on a stock's float can significantly impact profitability. Low-float stocks might be targeted for quick, speculative trades, while high-float stocks may be used for strategies requiring more predictability and less slippage.

  • Risk Management: Day traders should consider the float size when assessing risk, as low-float stocks can experience sudden and sharp price movements.


For day traders, mastering the concepts of stock float and free float is essential for developing effective trading strategies. These metrics not only influence choice of stock but also dictate the approach to volatility, risk management, and potential profitability within the day trading paradigm. By focusing on the implications of stock floats, day traders can better navigate the complexities of the market, making informed decisions that align with their short-term trading objectives.
