A new paper argues that factor investing challenges the decades-old Capital Asset Pricing Model (CAPM), according to an article in Institutional Investor. The paper’s co-author, Northern Trust Asset Management’s head of quantitative strategies Michael Hunstad, said in an interview: “CAPM asserts that if you want more return you take more risk.

Investors: Consider revenue-weighted ETFs

Citing Schroders research, the article reports that over the past five years, about 60% of funds flowing into US equity ETFs has gone to alternative equity index strategies rather than those based on market capitalization, but the returns have been largely disappointing.

Five Questions: A Wealth Manager’s View of Factors with Michael Batnick

By Jack Forehand (@practicalquant) — Factor Investing poses some interesting challenges for wealth managers. On one hand, the evidence is very strong that investing using factors produces superior to returns to market cap weighted indexes over the long-term. On the other, factor strategies introduce another set of behavioral problems for clients because the extended periods of underperformance that are common in factor investing can lead to bad decision making and underperformance relative to index funds… Read More
