What would typically not be included in cash from operating activities?

Cash from operating activities primarily reflects the cash flows generated from a company’s main business operations. This includes revenues received from sales, changes in working capital such as accounts receivable, and non-cash adjustments like depreciation.

Investments in equity securities are generally classified under cash flows from investing activities, not operating activities. This is because such investments are related to the acquisition or sale of long-term assets or financial investments rather than the day-to-day operations of the business. Understanding this classification is crucial for analyzing a company's cash flow statement as it provides insights into how well a company can generate cash from its core activities separate from investment actions.

The other options, such as depreciation, changes in accounts receivable, and sales revenue, are integral components of operating cash flow. Depreciation is added back to net income as it is a non-cash expense, changes in accounts receivable affect the cash flow depending on whether sales are on credit, and sales revenue reflects the cash generated from the core business operations.
