“The reality of risk is much less simple and straightforward than the perception. People vastly overestimate their ability to recognize risk and underestimate what it takes to avoid it; thus, they accept risk unknowingly and in so doing contribute to its creation.
“Risk arises as investor behavior alters the market. Investors bid up assets, accelerating into the present appreciation that otherwise would have occurred in the future, and thus lowering prospective returns. And as their psychology strengthens and they become bolder and less worried, investors cease to demand adequate risk premiums. The ultimate irony lies in the fact that the reward for taking incremental risk shrinks as more people move to take it.
