Is it possible that factor investing won't work?
Notas do episódio
A longtime listener wrote in after watching a Ben Felix video making the point that factor investing may not beat the S&P 500 by the end of an investor’s lifetime — and could even do worse. His question was simple: is factor investing really worth the effort?
Paul’s answer turned out to be two answers, so he’s splitting it into two episodes. This week is about the thinking. Next week is about the evidence — including new data Daryl Bahls just sent over.
Paul also tries something new: using AI to canvas the writings of the Truth Tellers and surface what they would say about this exact question. What emerges is a point they all agree on — good decisions do not guarantee good outcomes, and bad decisions sometimes produce wonderful ones. Bill Bernstein, Larry Swedroe, Ben Felix, Mike Piper, Christine Benz, Rob Berger, Jim Dahle and Jack Bogle each frame the same distinction: expected returns are not realized returns, and probability is not certainty.
Investing is one long series of forks in the road — save or spend, stocks or bonds, index or active, buy-and-hold or market timing — and none of them come with a guarantee. What they come with is a probability. The job is to choose thoughtfully, accept the uncertainty, and have the courage to stay the course while the evidence still supports the plan.
