What does an excellent motivational speaker in New York City has in common with the great depression of 1929. It is probably around this time when this concept was first being thought about. Wall Street market crashes are common and a major one occurred in 1929. It is the most devastating stock market crash in the history of United States.  This crash affected the Western industrial countries. Just before the crash, the market sustained very high level in the stock prices. On October 29, the optimism and financial gains bore down the market. The share price in the New York Stock Exchange collapsed.  The market price fall continued for a full month. Gradually, the crisis affected the real estate in US. The market was unstable during the whole month. The Dow Jones Industrial Average further slipped in Nov - Dec 1929 and reached down in the lowest level in the financial market history - a fertile opportunity for a motivational speaker in New York. In that month the markets sharply fell down, which in the initial leg, was down close to 17% of its value. On the trading floor, Wall Street bankers found the solution to the panic and chaos and chose as the vice president of the exchange, Richards Whitney. In the stock market thousands of Americans had invested by borrowing money to invest more. More people invested and this led to the rise of the share prices. Speculation created an economic bubble and fuelled further rises.  In September 1929, the average price to earnings ratio of stocks was 32.6. In the modern economic history this event was the most dramatic one. The US Senate studies the causes of the crash by establishing Pecora Commission. In 1933, Glass- Steagall Act was passed by the US Congress, which extended loan, take deposits and investment banks. This is not 1929, but should change and uncertainty plaque your organization, book a motivational speaker in New York.
