It is important to understand why this capitalization rate for small, privately held companies is significantly higher than the return that an investor might expect to receive from other common types of investments, such as money market accounts, mutual funds, or even real estate. Those investments involve substantially lower levels of risk than an investment in a closely held company. Depository accounts are insured by the federal government (up to certain limits); mutual funds are composed of publicly traded stocks, for which risk can be substantially minimized through portfolio diversification.
