Explanation:
The stock market crash followed a speculative 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 borrowing money to buy more stocks. There was an initial stock market crash that triggered a "panic sell-off" of assets. This was followed by a deflation in asset and commodity prices, dramatic drops in demand and credit, and disruption of trade, ultimately resulting in widespread unemployment (over 13 million people were unemployed by 1932) and impoverishment.
