Taobiz explains Market Basket
For investors, the market basket is the principal idea behind index funds. A sample of stocks, bonds or other securities are placed in a portfolio that is expected to represent all aspects of the market. This provides investors with a benchmark against which to compare their investment returns.
Another popular market basket relates to the Consumer Price Index , which tracks a variety of consumer goods. The CPI looks at the price levels of consumer products and provides an estimate for inflation.
