Dr. Daniel Crosby on Behaviorally Optimal Portfolios, Risk Composure and the Casino Myth

Diversified long-term US investing is far from a casino; no meaningful US period lacked extraordinary outcomes.

Crosby pushes back on the common view that investing is a casino. He argues that if you have diversified your assets and stayed invested for the long term, there has been no meaningful period in American history without an extraordinary outcome. The 'Wall Street casino' framing, in his view, is inaccurate, and it is damaging because it leads people to avoid long-term equity investing. He offers no specific data in this passage beyond the historical claim.

“If you diversified your assets and been long term, there's basically been no meaningful period of time in American history where you haven't had an extraordinary outcome. Like, it's the furthest thing from a casino.”at 28:56

Investors wrongly assume straight-line returns and see markets as less volatile than they are; they'll relearn it the hard way.

Crosby says many people, especially FIRE-minded savers, make straight-line assumptions about markets. They assume 10% a year for life, with no sequence-of-returns risk and no adjustment for valuations. He attributes this to primacy and recency effects: early and recent investing experiences loom large, so a growing share of people believe markets are less volatile than they really are. He expects that lesson will eventually have to be relearned, probably painfully. He gives no timing and no quantified forecast.

“I see a lot of people making straight line assumptions about markets. ... for an increasingly large swath of the population, they think that markets are less volatile than they actually are.”at 30:06

Stock-picking opportunities are growing as crowds pile into one side, though mispricing can persist a long time.

Crosby is skeptical of the familiar claim that 'this year it's finally a stock picker's market', noting markets can stay behaviourally irrational for a very long time. He still argues that opportunities are being created as more and more people crowd onto one side of the trade, so mispricing grows. He warns it can take a long time for that boat to tip. The argument is general and offers no specific holdings, data or timeline.

“I do think that opportunities are being created as more and more people crowd into one side of the boat. I do think you get more and more opportunities.”at 38:42

Most funds marketed as active are closet index funds; about three-quarters don't meaningfully differ from benchmarks.

Crosby cites research from Wes Gray and his team to argue that much of what is nominally active asset management is passive management in disguise. He says about three-quarters of what gets marketed as active doesn't differ meaningfully from a benchmark. He concludes that investors who only want to match the market can simply index, but those who want to outperform must hold portfolios that look different from the benchmark, enough to be meaningful but still diversified.

“a lot of what is nominally asset management is just passive management in sheep's clothing. ... about three quarters of what gets marketed as active doesn't differ meaningfully from a benchmark.”at 23:14

Sports betting and prediction markets have done a great disservice to the investing community and pose a formula for disaster.

Crosby argues that sports betting and prediction markets have harmed the wider investing community. He links this to economic strain: inflation and policy choices have left people, especially young people, feeling strapped and unable to follow the conventional path to wealth, so they 'throw Hail Marys.' Pairing that desperation with the easy access of sports betting and prediction markets makes a 'formula for disaster.' He also describes the apps as engineered for maximum addictiveness, with variable reward structures that make users feel expert, engaged and hopeful, and compares them unfavourably with long-term diversified index investing. He says people conflate gambling with long-term investing, which he calls 'the furthest thing from a casino.'

“I think that prediction markets and sports betting in particular have done a great disservice to the larger investing community.”at 24:48

AI will automate low-value advisor work, freeing advisers for client relationships, but that payoff isn't guaranteed.

Crosby argues that the best value investment advisers add is human: connecting with clients and keeping them from big mistakes. Research shows the best predictor of a client following that guidance is how much they like the adviser. He thinks AI frees advisers to automate lower-value tasks and become more relational. He cites the rise in leisure time, which people mostly spend scrolling and watching Netflix, to argue that the capacity freed up may be wasted unless the industry deploys it meaningfully.

“I feel like this frees us up to automate some of the lower value add parts of our work and to become more deeply relational and more deeply human with our clients. But I don't take for granted that that will happen.”at 44:47
