Beta coefficient, of an individual security or portfolio, helps to volatility relative to the market. The market's beta is always one, regardless of market conditions. A beta of more than one means the portfolio is more sensitive to price movements than the market. A beta of less than one means the portfolio is less sensitive to price movements than the overall market. In rising market conditions, a higher beta may mean more potential price appreciation. However, a higher beta also means more potential portfolio risk.
A client's securities portfolio has an average beta of 1.8. The client's holdings will rise or fall faster than the overall market.
