To articulate the market-top question without pretending he can answer it, Spencer Jakab turns to one of Wall Street's most enduring stories [1] — Spencer Jakab "Joe Kennedy made his fortune by selling before the 1929 crash after a shoeshine boy started giving him stock tips.

Joe Kennedy, the Kennedy family patriarch and once one of the richest men in America, famously avoided the Great Crash of 1929 by selling his stock holdings after a shoeshine boy began offering him tips. Kennedy's reasoning was elegant: if a shoeshine boy knows as much as I do — and has been right — something is wrong with the market. Jakab draws the parallel explicitly to today's retail AI enthusiasm, noting that ordinary investors who buy into hot themes online and have been right for a while create the same uneasy signal. He is careful to add that bull markets produce many false alarms; plenty of smart people have called the top too early. But the anecdote itself is the point: the question deserves to be asked.
Joe Kennedy famously sold his stocks after a shoeshine boy gave him stock tips, correctly sensing the 1929 market top — Spencer invokes this as a warning for 2026.
Joe Kennedy made his fortune by selling before the 1929 crash after a shoeshine boy started giving him stock tips. When everyday people become stock market experts, the smart money gets nervous. Spencer Jakab tells this story for a reason: retail AI excitement today looks a lot like 1929.

The ceiling on future returns is structurally lower — the best realistic outcome is a doubling, which any number of less exciting stocks can also deliver.
