DECIMALIZATION

A system where security prices are quoted using a decimal format rather than fractions. For example, this is a decimal trading quote: $34.25. Using fractions, the same quote would appear as $34 1/4. The U.S. Securities and Exchange Commission ordered all stock markets within the U.S. to convert to decimalization by April 9, 2001, and all price quotes since appear in the decimal trading format. Decimalization has led to tighter spreads because of the corresponding smaller price increments and movements. For example, prior to decimalization, one-sixteenth of one dollar was the smallest price movement that could be represented in a price quote.
