The use of numerical or measurable information in evaluating a security, company, or market.

Examples of this type of information include characteristics such as cash flow, option pricing, value of assets, cost of capital, historical and projected patterns of sales, costs, and profitability, market share, and financial ratios such as earnings per share. This information may be implemented through the use of mathematical and statistical modeling. Its applications include the formation of predictions and strategies, measurement, performance evaluation, and valuation of a financial instrument. Quantitative analysis must be used in conjunction with qualitative analysis to give a complete picture of any situation.
