On October 29, William C. Durant joined with members of the Rockefeller family and other financial giants to buy large quantities of stocks in order to demonstrate to the public their confidence in the market, but their efforts failed to stop the large decline in prices. Due to the massive volume of stocks traded that day, the ticker did not stop running until about 7:45 p.m. that evening. The market had lost over $30 billion in the space of two days which included $14 billion on October 29 alone.[17]
