There may also be private investment pools, which may have some characteristics of securities. Generally, securities are represented by certificates or electronic book entry interest. The certificates can be bearer or registered. Investorwords.com defines securities as "Property which is pledged as collateral for a loan" (http://www.investorwords.com/4446/security.html).
