Stock investing involves owning an interest in a public company and evaluating both the business and the price paid for that ownership. This guide explains the key concepts in practical terms.
Why cash flow matters
Profit reported under accounting rules and actual cash movement are not the same thing. The cash-flow statement helps investors track cash generated and used during a reporting period.
Operating activities
Operating cash flow generally reflects cash related to the company’s core business activities, with adjustments for noncash items and changes in working capital.
Investing activities
This section can include purchases and sales of property, equipment, investments and businesses. Large capital expenditures may be necessary to maintain or expand operations.
Financing activities
Financing cash flows can include borrowing and repaying debt, issuing or repurchasing shares and paying dividends.
Free cash flow
Investors often discuss free cash flow, commonly calculated using operating cash flow and capital expenditures. Definitions can vary, so check how a company or analyst calculates a non-GAAP measure.
Connect all three statements
The cash-flow statement is most useful when read with the income statement and balance sheet. Together they provide a broader picture of profitability, financial position and cash generation.
