Decimal pricing

Decimal Pricing

The listing of a security's price in decimals instead of fractions. For example, decimal pricing means that a security would be listed as, say, $25.25, instead of $25 1/4. Decimal pricing makes prices and the market more understandable for investors and laypeople.

Decimal pricing.

US stocks, derivatives linked to stocks, and some bonds trade in decimals, or dollars and cents. That means that the spread between the bid and ask prices can be as small as one cent.

The switch to decimal stock trading, which was completed in 2001, was the final stage of a conversion from trading in eighths, or increments of 12.5 cents.

Trading in eighths originated in the 16th century, when North American settlers cut European coins into eight pieces to use as currency. In an intermediary phase during the 1990s, trading was handled in sixteenths, or increments of 6.25 cents.
