Which of the following can we conclude based on our observation of capital market history from 1926 to 2016? (Hint: this is the "Second Lesson" from capital market history) O Securities perceived to be riskier had lower returns on average than securities perceived to have low or no risk. O Securities with lower returns had returns with greater risk (i.e., standard deviation of returns). O Securities had greater risk premiums due to having lower returns, on average. O We observed no relation between a stock's risk premium and standard deviation. Securities with greater risk premiums had returns with greater risk (i.e., standard deviation of returns)
