Alice’s Adventures in Factorland

Over the last 15 years, factor returns have not delivered on investors’ expectations. Are factors broken or far riskier than investors believe? Investors could dismiss the approach based on recent poor performance, but perhaps a better path would be to gain an understanding of three risks associated with factor investing. Doing so can help investors form more realistic return expectations.

All of the well-established factors to which investors gain exposure in low-cost smart beta funds are expected to deliver a premium in the long run, but none is guaranteed to outperform at all times.
