Stock price doesn’t determine what the real value is. Shares are traded up and down on speculation of what the “share” value is...not what the company value is.
A change in share price doesn’t change the money the company has or can use.
Shareholders of existing issued stock are not investors. People who put up money to buy new shares issued are.
Trust me, I’m living the reality with the SEC now and raising funds for the company to use. Our stock price jumped 20% in the last week but it didn’t put a nickel in our pockets to use. We still need to leverage the shares and sell new ones to raise capital. Existing shares do nothing for us.
