stra∙te∙gic as∙set mix (noun)
An investor’s long-term mix of stocks, bonds, cash and other investments that will provide her with the best opportunity to achieve her objectives. It should take into consideration an investor’s goals, risk tolerance, and investment time horizon.
An investor should not alter her Strategic Asset Mix unless she experiences a change in her personal circumstances such that her investment objectives, risk tolerance or time horizon change. The SAM will evolve over time due to the inevitability of aging, but major shifts should not be made in reaction to short-term market moves.
The above term is taken from The Steadyhand Dictionary, which is designed to help you sift through and make sense of the investment industry's dialect. Think of it as the little black book of investing.
