Understanding Float in Investing: An Overview with Examples

Updated: Feb 11

In the world of finance and stock markets, various terminologies are used by professionals that may seem esoteric to the uninitiated. One such term is “float”. Understanding float is vital for investors as it can provide insights into stock liquidity, potential volatility, and the overall dynamics of a company's shares.

What is Float?

In the simplest terms, float refers to the number of shares of a company that are available for trading by the general public. It is derived by subtracting the number of closely-held shares (by insiders, employees, the company's Employee Stock Ownership Plan, or other major long-term shareholders) from the total number of outstanding shares.

Formula: Float = Total Outstanding Shares − Closely-held Shares

Why is Float Important?

  • Liquidity: A larger float generally indicates more liquidity, meaning there are more shares available for trading. This can lead to smaller price fluctuations since large trades have less impact.

  • Price Manipulation: Companies with a smaller float can be more susceptible to price manipulation, as a single investor purchasing a large portion of available shares can dramatically influence the stock price.

  • Short Selling: The float is important for those looking to short sell a stock. If a significant percentage of the float is being shorted and the stock starts to rise, it can lead to a "short squeeze" where short sellers scramble to cover their positions, driving the price even higher.

Examples of Float in the Real World

  • Large Float: Consider a company like Apple Inc. With billions of shares outstanding and a significant portion available to the public, it has a large float. This often results in more stability in its stock price movements compared to a company with a smaller float.

  • Small Float: Now, consider a startup that has just gone public. Let's say it has 10 million shares outstanding, but 4 million of these are held by insiders and cannot be traded. This leaves a float of 6 million shares. Any large purchase or sale can lead to significant price swings.

  • Short Squeeze: Using our startup example, imagine if 3 million of its 6 million float were shorted by investors expecting the price to go down. If instead, the company announces positive news and the stock starts to rise, these short sellers might rush to buy shares to cover their positions. With a limited number of shares available for trading, this increased demand can drive up the price very quickly.

Factors Influencing Float

  • Share Repurchases: If a company buys back its shares, the number of outstanding shares decreases. This can result in a decrease in the float if the repurchased shares are from the public pool.

  • Secondary Offerings: If a company issues more shares to the public, the float can increase, thereby potentially offering more liquidity.

  • Insider Activity: If company insiders decide to sell a large portion of their holdings, the float can increase. Conversely, if they buy up more shares, the float can decrease.

  • Lock-up Periods: After an IPO, insiders are often prohibited from selling their shares for a certain period, known as the lock-up period. Once this period expires, the float might increase if insiders decide to sell.

Understanding float is crucial for investors, especially those active in trading. It provides insights into the potential volatility of a stock, its liquidity, and how susceptible it might be to certain market dynamics like short squeezes. As always, it's one of many factors to consider when analyzing a potential investment.
