Greenwich LifeSciences  (NAS:GLSI) Shares Outstanding (Diluted Average) Explanation

A company may buy back shares or issue shares in any fiscal period. If a company buys back shares, we should observe that the total number of shares decline. If the company issues new shares, the number of shares outstanding increases.
