You’ve probably heard about the stock market (the big guys also known as stock exchanges). There are lots around the world. In the U.S., amongst the biggest and most well known are the New York Stock Exchange (NYSE) and the NASDAQ.
These stock markets have minimum requirements to allow companies to have their stock traded there. When a stock can be traded on one of these exchanges, it’s called “listed” on that exchange. For instance, Ford Motor Company is listed on the NYSE.
Most companies that take advantage of Reg. A / Title IV / Tier 2 will not initially meet the large exchanges’ minimum requirements. They will trade over the counter (OTC).
There are advantages to companies and investors to trading stocks listed on the NYSE and NASDAQ, but it is very expensive.
