The success of Piggly Wiggly was phenomenal, and other independent and chain grocery stores changed to self-service in the 1920s and 1930s. At its peak in 1932 (see Clarence Saunders), the company operated 2,660 stores and posted annual sales in excess of $180 million. In November 1922, Saunders attempted a squeeze on the substantial short interest in the stock, running the share price up from 40 to 120 and profiting by millions on paper. The Stock Exchange Governors responded by deciding that a corner had been established in Piggly Wiggly and removed the stock from the Board, eventually forcing Saunders to turn over his assets to the banks that had financed his leveraged position. Saunders reputedly lost nine million dollars in the attempted corner.
