The capital market theory builds upon the Markowitz portfolio model:
5. All Assets are Infinitely Divisible - This indicates that fractional shares can be purchased and the stocks can be infinitely divisible.
6. No Taxes and Transaction Costs -assume that investors' results are not affected by taxes and transaction costs.
7. No Inflation Exists - Returns are not affected by the inflation rate in a capital market as none exists in capital market theory
8. There is No Mispricing Within the Capital Markets - Assume the markets are efficient and that no mispricing within the markets exist.
