Before April 9, 2001, when the Securities and Exchange Commission ordered all U.S. stock markets to switch to the decimal system, prices were reported and stocks were denominated in fractions - in one-sixteenths (1/16), to be exact.
The West Coast Stock Exchange declared that October 21, 2020, would be "Taking A Look Back" Day. The stock exchange decided to revert back to reporting stock prices as fractions just as they did prior to 2001.
The graph above shows the change in the stock prices for SLINK Inc. on October 21, 2020. The change in the stock prices were represented as fractions in honor of the West Coast Stock Exchange's "Taking A Look Back" Day.
