The Anatomy of a Stock Market Bubble

Since early December, the Nasdaq Composite Index has lost over 10% amid rising volatility and fears of a recession. These falls come from lofty levels: Over the past decade, the Index quadrupled, pushing valuations into overheated territory.

Are we starting to see the bursting of the large asset price bubble we warned about in The 2025 Picton Report?

We believe the signs point to yes. Historically, bull runs of this magnitude have been associated with unsustainable booms that left investors nursing significant losses:

  • The Roaring 20s saw a rise of 451.2% in the Dow Jones Industrial Average, followed by a decline of 66.3% in The Great Crash.
  • During the Japanese Asset Price Bubble that peaked in 1989, the Nikkei 225 Index climbed 407.9% and subsequently gave back 40.6%.
  • In the DotCom Bubble, the Nasdaq Composite Index soared 538.2%, then fell 56.8%.

By the Numbers: It Sure Seems like a Bubble

From valuations to household allocations, U.S. equities seem to tick off many key attributes found in a bubble—beyond simply the extent of their rise.

 

Preparing for what’s ahead

Rather than betting on a potential crash, investors can consider a more cautious approach with multi-asset strategies that aim to balance risk and achieve long-term returns.
