Take a look at this chart of Dow Jones for the last 100 years: http://www.macrotrends.org/1319/dow-jones-100-year-historical-chart. The gray vertical bars denote a recession. Also take a look here: http://www.nber.org/cycles.html for a list of these recessions and the time it took from peak to trough – from the the high point in the cycle to the lowest. How do the peaks / troughs in the stock market compare with the peaks / troughs in the business cycles? What leads and what follows? Write a detailed description of your observations and your conclussions.
