WHat is percent of shares outstanding mean?

Answer 1

Shares outstanding is the total number of share that exist for that company, and a percentage of that would be the percentage of ownership.

Example:
2,000 shares exists for a company, or 2,000 share outstanding. if you owned 100 of those shares your percent of shares outstanding would be 100/2,000 or 5%. that would mean that you own 5% of the company.

Answer 2

Shares outstanding is the number of shares that are fully paid up and outside the company. A company can sell x number of shares. But it sells ony y which is less than x for the time being. (y/x)100 is the percentage of shares outstanding.
