Investing Fundamentals: EPS, Market Cap, Revenue, Margins, Debt, and Cash Flow

When you are investing for years, not days, fundamentals matter more than intraday noise. This checklist helps you evaluate business quality behind the headlines.

Core indicators

  • Earnings per share (EPS): profit allocated to each share.
  • Market cap: total market value of the company.
  • Revenue growth: whether demand is expanding.
  • Margins: whether growth converts into profit.
  • Debt: whether the balance sheet can survive stress.
  • Free cash flow: whether profits become usable cash.
  • Valuation: what we pay for the future earnings stream.

This is where investing differs from trading. Investing seeks durable ownership and compounding. Trading seeks tactical returns and must use a smaller, risk-controlled capital allocation.
