In the financial world, understanding various metrics and terms is crucial for making informed investment decisions. One such term that often pops up in financial discussions is “free float.” For those unfamiliar with the concept, free float might sound like an abstract financial jargon. However, it is a critical measure that impacts stock liquidity, price discovery, and overall market dynamics. This article aims to demystify the term free float, explain its significance, and provide insights into how it affects stock trading.
What is Free Float?
Free float, also known as public float, refers to the shares of a company that can be publicly traded and are not restricted. In simpler terms, it represents the number of shares available to the general public for trading in the secondary market. These shares are not held by insiders such as corporate executives, directors, or major long-term shareholders who typically hold their shares for a very long-term basis.
To understand free float better, let’s break it down into its components:
Outstanding Shares: These are the total number of shares held by all the shareholders of a company.
Restricted Shares: These are shares that are not transferable until certain conditions are met. Restricted shares are generally held by insiders such as corporate management, including executives and directors.
Treasury Shares: These are shares that have been repurchased by the company and are held in its treasury. They are not available for public trading.
The formula to calculate free float is:
Free Float = Outstanding Shares – Restricted Shares – Treasury Shares
For example, let’s consider a publicly traded company, Company A, which has 1,000,000 shares authorized. According to its balance sheet, the total outstanding common shares number 500,000. Out of these, 50,000 shares are held by the CEO and CFO of the company, and 80,000 shares are held in treasury. Therefore, the free float of Company A is calculated as follows:
Free Float = 500,000 – 50,000 – 80,000 = 370,000 shares
Note that in the example provided initially, the calculation resulted in 450,000 shares. However, this has been corrected to reflect a more accurate calculation based on the information given.
Significance of Free Float
Free float is a critical metric for several reasons:
1. Stock Liquidity
Impact on Trading Volume: The higher the free float, the more shares are available for trading in the market. This generally leads to higher trading volume, which can enhance liquidity.
Ease of Trading: A larger free float makes it easier for investors to buy and sell shares without significantly impacting the stock price.
2. Price Discovery
Efficient Markets: In a market with a high free float, a larger number of participants can trade, leading to more efficient price discovery.
Reduced Volatility: With more shares available for trading, the impact of any single trade on the stock price is minimized, potentially reducing volatility.
3. Index Inclusion
Eligibility Criteria: Many stock indices, such as the S&P 500, have specific criteria for a company’s free float. For example, a company must have a sufficient free float to be eligible for inclusion in the S&P 500.
Weighting in Indices: The weight of a company in an index is often based on its free float-adjusted market capitalization.
4. Corporate Governance
Alignment of Interests: A higher free float can sometimes lead to better corporate governance as the interests of a larger number of shareholders are aligned.
Monitoring by Investors: With more shareholders, there is greater scrutiny and monitoring of corporate actions, potentially leading to better decision-making.
5. Valuation and Risk Assessments
Investor Perceptions: The free float can impact investors’ perceptions of a company’s risk and valuation. A higher free float might be seen as less risky due to increased liquidity and broader ownership.
Cost of Capital: A company with a higher free float may have a lower cost of capital as investors are willing to pay a lower premium for liquidity.
Free Float and Stock Liquidity: Evidence from Studies
Several studies have examined the relationship between free float and stock liquidity. Here’s a look at some of the key findings:
1. Impact of Regulatory Interventions
In June 2010, the Securities and Exchange Board of India (SEBI) mandated listed firms to increase their Minimum Public Shareholding (MPS) to 25%. A study by M Jawed, KK Kotha, and V Gupta utilized this regulatory intervention to examine the impact on stock liquidity. The study found that the MPS regulation significantly improved different stock liquidity measures and established a causality between stock free float and stock liquidity.
2. Foreign Ownership and Liquidity
A study by SG Rhee and J Wang examined the relationship between foreign institutional ownership and stock market liquidity in Indonesia from January 2002 to August 2007. The study found that foreign institutions held almost 70% of the free-float value of the Indonesian equity market, which significantly impacted liquidity.
3. Institutional Ownership and Liquidity
Another study by P Agarwal focused on the critical role of liquidity in asset price discovery, sharing of financial risk, and transaction costs reduction. The study highlighted the importance of understanding institutional ownership in relation to stock liquidity.
4. Historical Returns and Free Float
A study by J Hamon and B Jacquillat presented evidence of a negative link between historical returns and free float. The link was significant even outside the month of January, suggesting that stocks with lower free floats tended to outperform those with higher free floats over longer periods.
5. Government Interventions
A study by K Chan, YC Chan, and WM Fong examined the impact of the Hong Kong Government’s intervention in the stock market in August 1998. The government bought up to HK$118.1 billion in shares of the 33 Hang Seng Index (HSI) component stocks, representing about 7.3% of all the shares. The study found that this intervention significantly impacted the free float and market liquidity of the affected stocks.
Practical Implications for Investors
As an investor, understanding free float is crucial for making informed decisions. Here are some practical implications:
1. Assessing Liquidity
Before investing in a stock, assess its free float to understand its liquidity. Stocks with a higher free float tend to have better liquidity, making it easier to buy and sell shares.
2. Monitoring Corporate Actions
Keep an eye on corporate actions that can impact a company’s free float, such as share repurchases, issuance of new shares, or changes in insider ownership. These actions can significantly affect the stock’s liquidity and trading characteristics.
3. Considering Index Inclusion
If you invest in index funds or ETFs, be aware of the criteria for index inclusion, which often include a company’s free float. Changes in a company’s free float can impact its inclusion in indices, potentially affecting the performance of your investments.
4. Risk Management
Consider the free float when assessing a company’s risk profile. Stocks with a higher free float may be less volatile due to increased liquidity and broader ownership.
5. Valuation Insights
Use free float as a supplementary metric when valuing a company. A higher free float might indicate a lower cost of capital and potentially a higher valuation.
Conclusion
Free float is a critical metric in the financial world that impacts stock liquidity, price discovery, and overall market dynamics. Understanding free float requires grasping its components—outstanding shares, restricted shares, and treasury shares—and how they interact to determine the number of shares available for public trading. By analyzing a company’s free float, investors can gain insights into its liquidity, corporate governance, and risk profile. Furthermore, studies have shown that free float significantly impacts stock liquidity, with regulatory interventions, foreign ownership, and government actions all playing crucial roles.
