Shares Outstanding Number of shares that are currently held by investors, including restricted shares owned by the company's officers and insiders as well as those held by the public. For companies with multiple common share classes, market capitalization includes both classes. Market Cap is calculated by multiplying the number of shares outstanding by the stock's price. Market Capitalization Reflects the total market value of a company. Earnings Per Share (TTM) A company's net income for the trailing twelve month period expressed as a dollar amount per fully diluted shares outstanding. P/E Ratio (TTM) The Price to Earnings (P/E) ratio, a key valuation measure, is calculated by dividing the stock's most recent closing price by the sum of the diluted earnings per share from continuing operations for the trailing 12 month period.
