The preferred stock effect is not a notion that can be used to explain abnormally high excess stock returns.
The term "stock" refers to a company's ownership or equity. Common stock and preferred stock are the two forms of equity. Preferred investors are entitled to more dividends or asset distributions than common stockholders. The specifics of each preferred stock vary depending on the issuance.
When it comes to dividends, preferred stockholders have a preference over ordinary stockholders, which typically yield more than common shares and might be paid monthly or quarterly. These dividends can be fixed or determined by reference to a benchmark interest rate, such as the London Interbank Offered Rate.
