Retail

A retail investor is any individual investor. Even fairly large individual investors are usually considered retail.

A retail broker is a broker who works with individual investors. Basically your classic stock broker.

A retail shop is a broker/dealer whose primary business is retail investors. For example, Charles Schwab or to a lesser extent, Merrill Lynch.

A retail bond is any bond designed to sell to retail investors. The classic example of a retail bond is one that has a relatively high yield but does not have a good total return profile, like many callable agencies.
