Floating stock is the number of shares available for trading of a particular stock. Low float stocks are those with a low number of shares. Floating stock is calculated by subtracting closely-held shares and restricted stock from a firm’s total outstanding shares.
Closely-held shares are those owned by insiders, major shareholders, and employees. Restricted stock refers to insider shares that cannot be traded because of a temporary restriction, such as the lock-up period after an initial public offering (IPO).
A stock with a small float will generally be more volatile than a stock with a large float. This is because, with fewer shares available, it may be harder to find a buyer or seller. This results in larger spreads and often lower volume.
KEY TAKEAWAYS
Floating stock refers to the number of shares a company has available to trade in the open market.
To calculate a company's floating stock, subtract its restricted stock and closely held shares from its total number of outstanding shares.
Floating stock will change over time as new shares may be issued, shares may be bought back, or insiders or major shareholders may buy or sell the stock.
Low float stocks tend to have higher spreads and higher volatility than a comparable larger float stock.
Investors can find it difficult to enter or exit positions in stocks that have a low float.
The amount of a company’s floating stock may rise or fall over time. This can occur for a variety of reasons. For example, a company may sell additional shares to raise more capital, which then increases the floating stock. If restricted or closely-held shares become available, then the floating stock will also increase.
On the flip side, if a company decides to implement a share buyback, then the number of outstanding shares will decrease. In this case, the floating shares as a percentage of outstanding stock will also go down.
Why Floating Stock Is Important
A company's float is an important number for investors because it indicates how many shares are actually available to be bought and sold by the general investing public. Low float is typically an impediment to active trading. This lack of trading activity can make it difficult for investors to enter or exit positions in stocks that have limited float.
Institutional investors will often avoid trading in companies with smaller floats because there are fewer shares to trade, thus leading to limited liquidity and wider bid-ask spreads. Instead, institutional investors (such as mutual funds, pension funds, and insurance companies) that buy large blocks of stock will look to invest in companies with a larger float. If they invest in companies with a big float, their large purchases will not impact the share price as much.
Special Considerations
A company is not responsible for how shares within the float are traded by the public—this is a function of the secondary market. Therefore, shares that are purchased, sold, or even shorted by investors do not affect the float because these actions do not represent a change in the number of shares available for trade. They simply represent a redistribution of shares. Similarly, the creation and trading of options on a stock do not affect the float.
