Informed Momentum Company CIO Travis Prentice breaks down why 52 week highs don't mean what you think, the extreme dispersion beneath the surface of the market, why traditional definitions of risk may be flawed, and how investors should think about momentum, quality, and diversification in a rapidly changing environment.
