Alpha Duties: The Search For Excess Returns And Appropriate Fiduciary Duties, Ian Ayres, Edward Fox Mar 2019

Alpha Duties: The Search For Excess Returns And Appropriate Fiduciary Duties, Ian Ayres, Edward Fox

Articles

Modern finance theory and investment practice have shifted toward “passive investing.” The current consensus is that most savers should invest in mutual funds or ETFs that are (i) well-diversified, (ii) low-cost, and (iii) expose their portfolios to age-appropriate stock market risk. The law governing trustees, investment advisers, broker–dealers, 401(k) plan managers, and other investment fiduciaries has evolved to push them gently toward this consensus.

Turning to sanctions, we find that the incidence of top officer resignation is greater for class-action-only lawsuits relative to SEC-only investigations. Our findings are consistent with the private enforcement targeting disclosure violations at least as precisely as (if not more so than) SEC enforcement.
