There are 3 categories of banks, the handful of so called Money Center Banks, the 12-15 Regional Banks and the largest 10 of these are sometimes called Super Regional Banks. The rest of the thousands of banks are called Small Local or Community Banks. Do not confuse these Regional Banks with the Fed's Regional Banks. Also note, there are Investment Banking stocks such as Goldman Sachs (GS) and Morgan Stanley (MS) and scores of much smaller investment bankers. The Money Center Banks also have their own Investment Banking divisions. All of these plus insurance companies (discussed in the next chapter), fall under the broader category called Financials.
