Key point: Remember: individual stocks can lose principal. This page provides education and a research framework only, not stock picks or entry/exit signals.
The income statement shows performance over a period
Revenue, costs, expenses, and net income help investors track profitability trends.
The balance sheet shows financial structure at a point in time
Cash, inventory, receivables, debt, and shareholder equity help assess financial flexibility and leverage.
The cash-flow statement shows how cash actually moved
Operating, investing, and financing cash flows add information that accounting earnings alone cannot provide.
Read all three together
Net income alone can hide changes in receivables, inventory, capital spending, and borrowing. Connecting the statements provides a fuller picture.
How to verify information
Start with company filings, exchange/regulatory sources, and primary disclosures before relying on media summaries or market commentary. When sources conflict, prioritize formal filings and primary sources.
Primary sources
General investing education only. Not a recommendation, trading instruction, or promise of returns.
