FYI: A contrarian timing approach—emphasizing factors or strategies trading cheap relative to their own historical norms, and deemphasizing the more expensive factors or strategies—can improve performance, but should be used in moderation to avoid increasing portfolio risk from a loss of diversification.
•Contrarian timing is a form of value investing, but is not the same as doubling down on value risk. Relative valuation may support investing in the value factor when value is cheaply priced, and conversely, may indicate avoiding the value factor when it is expensive
