ANECDOTE

Tech Bubble Memory Against Quitting Value

  • Asness recalled clients praising sticking with value after the tech bubble while contrasting Julian Robertson closing his fund and leaving.
  • He used this to show sticking with a belief isn't always bravery but often necessity when you lack alternatives.

  • The 'different this time' story deserves respect but usually fails; Asness leans toward behavioral explanations for value's history.
  • Recent value underperformance showed fundamentals and other factors stopped working, suggesting irrational price momentum dominance.

  • Today's expensive growth companies are real businesses with strong products, unlike many frivolous dot-com era firms.
  • That makes current valuations excessive but less blatantly nonsensical than 1999–2000 bubble darlings.
