The Stock Market Crash of 1929 occurred during a period of unregulated wealth and excess. On October 14, 1929, investors were selling stock in large amounts. In order to halt the slide in the Dow Jones, the market indicator for the purchase and sale of stocks, Richard Whitney, the Vice President of the Stock Exchange, initiated a plan to purchase large quantities of blue chip stocks, stocks in large and reputable companies. This action resulted in temporarily halting the slide in stocks. The value of the market had increased tenfold in the 1920's as a result of speculation and inflated value in the market. A margin call occurs when value of the account falls below the broker's required minimum. While Whitney invested in the market to halt complete collapse, Charles Merrill of Bank of America suggested that his clients eliminate their financial obligations entirely.
