"One way to measure market risk is by calculating a portfolio’s beta. Beta shows how much a portfolio fluctuates when the market as a whole fluctuates. A higher beta means that the portfolio is exposed to more risk. The market has a beta of 1.0. In this example: The Optima Equity Fund has a beta of 1.4, which means the Fund is expected to be 1.4 times more volatile than the market as a whole. If the S&P/TSX Composite Index is used to measure the performance of the Optima Fund, then if the Index rose by 10% you would expect to see the Optima Fund rise by 14% (1.4 × 10%)."
