Institutions holding shouldn't indicate whether it's restricted or not?
What is Floating Stock?
Floating stock is the number of shares available for trading of a particular stock. 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.
