Mednax Inc has a beta of 1.0866. Let's try to break down what Mednax's beta means in this case. As the market goes up, the company is expected to outperform it. However, if the market returns are negative, Mednax will likely underperform. The beta indicator helps investors understand whether Mednax moves in the same direction as the rest of the market, and how volatile (i.e., risky) it is compared to the market (i.e., selected benchmark). In other words, if Mednax deviates very little from the market, it does not add much risk to the portfolio, but it also doesn't increase the expected returns.
