Floating stock refers to the shares of a company that can be traded on the stock exchange. Understanding floating stock helps investors evaluate a stock's liquidity, price movements, and a company's market position.
This article explains what a floating stock is, its features, and how to calculate it.
Key Takeaways
- Higher float implies improved liquidity, since more shares are available for trading by the public.
- Lower float means fewer shares are available for public trading, which increases volatility because small changes in supply or demand can cause price fluctuations.
- The shares held by promoters, founders, governments, or any other closely held individuals may not be included in the public float.
- Floating stock can change over time because of share sales, new share issues, buybacks, or changes in ownership.
- Free-float information helps investors understand how much of a company is actually available to the public.
What are Floating Stocks?
A company can issue millions or even billions of shares. Not all these shares are tradable.
A large portion may be locked up by the company's founders, promoters, directors, or major institutional investors who hold it as a long-term investment. The remaining portion, the shares that are freely available in the open market for the public to buy and sell on a daily basis, is referred to as the floating stock.
Example:
Let's consider a company with 10 million shares. Of these:
- 3 million shares belong to the founders.
- 2 million shares are held by the government or strategic investors.
- 1 million shares are held by directors and employees who do not trade their shares.
- 4 million shares are available to public investors.
In this scenario, the company has a total of 10 million shares, but its floating stock is about 4 million shares. In other words, only 40% of the company's total shares make up the firm's floating stock.
| Shareholder Category | Number of Shares | Status / Availability |
| Founders | 3 million | Closely held / Restricted |
| Government & Strategic Investors | 2 million | Locked-in / Non-tradable |
| Directors & Employees | 1 million | Held internally / Non-tradable |
| Public Investors | 4 million | Floating stock (tradable) |
| Total Outstanding Shares | 10 million | 100% of company shares |
How to Calculate Floating Stocks?
Floating stock can be calculated by first identifying the total number of ">outstanding shares and then excluding shares that are not publicly traded.
Floating Stocks Formula
Total Outstanding Shares − Closely Held/Restricted Shares
Example:
Assume that a company has the following shares:
- Total outstanding shares = 10 million
- Promoter-held shares = 3 million
- Shares held by Government/Strategic investors = 1 million
- Restricted or closely held shares = 1 million
Then,
Floating Shares = 10 million − (3 million + 1 million + 1 million)
Floating Shares = 5 million
This means that 5 million shares are available for public trading.
Floating Stock Percentage
The percentage of shares that are floating may also be determined:
Floating Stock % = (Floating Shares ÷ Total Outstanding Shares) × 100
In the above example,
(5 million ÷ 10 million) × 100 = 50%
Thus, 50% of the outstanding shares are available for public trading.
Note: The exact calculation may vary depending on the rules of a particular stock exchange or index provider, especially regarding promoter, insider, government, and strategic holdings.
In India, regulatory bodies like SEBI (Securities and Exchange Board of India), along with stock exchanges like BSE and NSE, mandate a Minimum Public Shareholding (MPS) of 25% for listed companies. This ensures that a baseline percentage of a company’s shares remains as floating stock to maintain market liquidity and prevent manipulation by insiders.
How Does Floating Stock Affect Stock Prices?
The floating stock can influence the extent of the market reaction to buying and selling pressures.
| Float Size | Market Impact & Liquidity | Key Characteristic | Why Investors Care |
| High Public Float | Higher trading volume and improved liquidity | Large number of shares available in the open market | Makes entering and exiting positions easier with minimal price disruption |
| Low Public Float | Lower supply and heightened sensitivity to orders | Small number of shares available for public trading | Even modest buy or sell orders can cause sharp price movements (higher volatility) |
Example:
Two companies receive equally positive news.
Company A has a massive floating stock. As many shares are listed on the market, buying pressure can lead to a small price increase.
Company B has a small floating stock. When investors buy shares of this company, the limited number of shares available can cause the price to change much more quickly.
It all depends on the simple law of supply and demand. If demand is high but supply is low, prices may rise quickly.
Features of Floating Stocks
There are certain characteristics associated with floating stocks, which include the following:
-
Available for public trading: Floating stocks refer to the shares of a company that are available for trading in the stock market by any investor.
-
Exclude locked-in shares: Promoter's shares, founder's shares, government's shares, and controlling shareholder's shares are excluded from the publicly traded shares if the shares are locked in.
-
Affects liquidity: A company with a large number of floating shares has better liquidity because more shares are available for buyers and sellers.
-
Influences price volatility: Stocks with a small public float can sometimes experience larger price movements because even a small change in demand or supply can have a greater impact on the price.
-
Different from total shares: Floating shares are not the same as total shares outstanding. A company may have a high number of total shares outstanding but a low number of publicly tradable shares.
| Float Size | Market Impact & Liquidity | Key Characteristic | Why Investors Care |
| High Public Float | Higher trading volume and improved liquidity | Large number of shares available in the open market | Makes entering and exiting positions easier with minimal price disruption |
| Low Public Float | Lower supply and heightened sensitivity to orders | Small number of shares available for public trading | Even modest buy or sell orders can cause sharp price movements (higher volatility) |
Floating Stocks vs Outstanding Shares: Key Differences
| Basis | Floating Stocks (Free-Float Shares) | Outstanding Shares |
| Meaning | Stocks that are freely tradable in the open market. | All stocks that have been issued and owned by stockholders. |
| Includes Promoter Shares? | Normally, no, if the promoter stocks are not freely traded. | Yes, promoter-held shares are included. |
| Includes Insider Shares? | Normally, stocks that are restricted and cannot be traded are excluded. | Yes, they can be included. |
| Size | Less than or equal to outstanding shares. | Greater than or equal to floating shares. |
| Trading Availability | Can be traded regularly in the market. | All outstanding shares may not be tradable in the market. |
| Effect on Liquidity | Helps in determining the liquidity of the stock. | Does not determine the liquidity of the stock. |
| Effect on Price Movement | Low float increases the volatility of the stock. | Total outstanding shares alone do not show how easily the stock can be traded. |
| Use in Indexes | Often used to calculate free-float market capitalisation. | Used to calculate the market capitalisation of the company. |
Note:
Major Indian benchmark indices, such as the Nifty 50, calculate index weighting using free-float market capitalisation rather than total market capitalisation. This means companies with a higher proportion of floating stock have a more accurate reflection of their market-tradable value, influencing the index.
Conclusion
The idea of floating stock is simple and yet very important in the investment world. It basically involves a company's publicly traded shares. The size of a company’s float can affect liquidity, trading activity, and price volatility. A high float indicates that more shares are available to trade, while a low float makes a stock volatile.
