SUITABILITY – The appropriateness of a particular security as an investment for a particular investor, taking into account the specific features of the security and the investor's financial capabilities and sophistication, tax status, investment objectives and other relevant considerations.  A security that seems appropriate for the investor in light of these factors is said to be “suitable,” whereas one that does not seem appropriate may be “unsuitable.”  Broker-dealers are required under MSRB rules to make suitability determinations before recommending particular investments or investment strategies to customers.  See: RECOMMENDATION.
