Wall Street- Economic Fundamentals
The crash followed a boom that had taken hold in the late 1920s. During the later half of the 1920s, steel production, building construction, retail turnover, automobiles registered, even railway receipts advanced from record to record. The combined net profits of 536 manufacturing and trading companies showed an increase, in fact for the first six months of 1929, of 36.6% over 1928, itself a record half-year. Iron and steel led the way with doubled gains. Such figures set up a crescendo of stock-exchange speculation which had led hundreds of thousands of Americans to invest heavily in the stock market. A significant number of them were to buy more stocks. By August 1929, brokers were routinely lending small investors more than two-thirds of the face value of the stocks they were buying. Over $8.5 billion was out on loan, more than the entire amount of currency circulating in the U.S. at the time.
