Stock

A security representing partial ownership in a company. Each share entitles the holder to a proportional claim on assets and earnings, with prices set by buyers and sellers on stock exchanges.

What stocks represent

A share of stock entitles holder to:

  • Proportional ownership of the company.
  • Claim on assets after liabilities (residual claim).
  • Dividend rights when declared.
  • Voting rights (typically) on major corporate actions.
  • Right to participate in liquidation proceeds.

The collective stockholders own the company.

Common vs. preferred

Two main classes:

  • Common stock — standard equity ownership; voting; junior in liquidation.
  • Preferred stock — fixed dividends; senior to common; usually no voting.

Most "stock" discussion refers to common stock.

Why stocks matter

For wealth creation:

  • Long-run returns — equities historically return ~10% nominal annualized in US.
  • Beating inflation — equity returns typically exceed inflation by significant margin.
  • Compounding power — long-term holdings produce substantial wealth.
  • Ownership claim on real businesses' future cash flows.

Stocks are foundational to long-term wealth building.

How investors hold stocks

Most retail:

  • Through brokerage accounts — Vanguard, Schwab, Fidelity, Robinhood.
  • Through retirement accounts — 401(k), IRA.
  • Through index funds and ETFs — diversified exposure.
  • Through mutual funds.

Direct individual stock holding is less common than fund-based exposure.

Stock returns

Historical patterns:

  • US stocks (S&P 500) — ~10% nominal, ~7% real annualized since 1928.
  • Wide variability — single-year returns range from -50% to +50%.
  • Long-term holding captures the upward drift.
  • Short-term timing is hard and often underperforms.

The boring math of long-term holding has produced most equity wealth.

Stock investing approaches

Several:

  • Index funds — passive, low-cost, diversified.
  • Active mutual funds — managed; often underperforms after fees.
  • Individual stock picking — concentration risk; potentially high return.
  • Dividend investing — focus on income-producing stocks.
  • Growth stocks — focus on appreciation.
  • Value stocks — focus on undervalued.

For most retail, broad index investing wins.

What individuals should know

For most retail:

  • Broad equity exposure is foundational to long-term wealth.
  • Index funds capture market returns at low cost.
  • Long-term holding beats trading.
  • Diversification reduces single-stock risk.
  • Don't time the market.

The basic principle: stocks represent ownership in real businesses. Long-term holdings of diversified equity exposure has been the primary path to wealth creation for most investors over multiple cycles.
