Explanation:

The market index is the financial tool usually used by investors and Financial managers in measuring the market and also used to compare returns on specific investments in the market like returns on stock investment can be compared using the stock market index tool.

The market index reached its lowest in 2009 due to the financial crisis ( recession ) that rocked the united states economy from late 2007 to early 2009. and the demand for commodities and stocks fell sharply in 2008 due to the recession that made investors loose confidence in buying stocks and commodities. It was a very strong bearish market ( selling off ) of stocks and commodities during this period.
