Scenario: Lets say I'm walking down main street and a company or two catch my eye as possible investment opportunities.
How do I go about finding if they have stock/shares to invest in? Some may say just look up the name of the company but some websites like "Robinhood" do not have all possible companies that sell stocks (they add more over time). Some of these companies have many retail stores in the US.
I hope my intent in this question came across.
