Efficient-market hypothesis (EMH)

The efficient-market hypothesis asserts that information is efficiently reflected in asset prices. Three forms of efficiency are identified:

  • Strong form: in its strong form, all information (including private information) is integrated intothe prices.
  • Semi-strong form: in this form, all public information is integrated into the price.
  • Weak form: in the weak form, past prices do not reveal any information on future prices.

ETFs offer investors access to diversified and passive liquid portfolios at low cost.
