Two of the nation's stock markets will make their first break from a pricing system that traces its roots back to Spanish "pieces of eight" Monday, when the New York and American stock exchanges begin trading a few stocks in increments of a penny, instead of fractions of a dollar.


New York Stock Exchange

will convert pricing for seven stocks to decimals from fractions in a test that's a precursor to a scheduled switch of all U.S. stocks and options trading to decimals by early next year. Historically U.S. markets have listed stocks and options in fractions of a dollar based on eighths -- or increments of 1/8, 1/16 or smaller.

Federal regulators want the markets to convert to decimals, which most major foreign bourses use. Regulators and members of Congress also believe trading in decimals will benefit investors by reducing the spread between the price at which a stock is offered and its sale price.

The companies included in Monday's decimalization trial run at the NYSE are

The AMEX plans to begin listing six equities in penny increments Monday. They are
