Summary

David Rosenberg, founder and president of Rosenberg Research, joins The Exchange to discuss record-high Russell 2000 and rising speculative risk in equity markets. He argues the small-cap rally is junky and prefers the quality-focused S&P 600. He also says AI dominance is spreading through the market but the total addressable market is uncertain, and he expects inflation to surprise to the downside, supporting Fed cuts and long-duration Treasuries.

  • Russell 2000 hits record highs and outperforms the S&P, raising speculative-risk concerns.
  • Rosenberg calls Russell 2000 the junkiest index and prefers S&P 600 quality.
  • Unprofitable companies have outperformed profitable ones by 2,000 basis points since Liberation Day.
  • AI and technology dominance has spread into energy infrastructure, utilities, pipelines, and financials.
  • Rosenberg questions AI total addressable market and compares investor behavior to the late-1990s internet bubble.
  • Inflation data were described as strong, with core inflation near target after stripping out tariffs.
  • Shelter disinflation and lower food and agriculture commodity inflation are seen driving downside inflation surprises through 2026.
  • The Fed is expected to cut rates eventually but is currently on hold and sounding hawkish until a new chair arrives.

Russell 2000 junky; prefer S&P 600 quality.
Russell 2000 is the junkiest index, with unprofitable and speculative companies leading the rally; he would rather focus on the S&P 600, which contains higher-quality small-cap companies.

Equity rally is speculative and junky.
The U.S. equity rally is speculative and junky, with unprofitable companies outperforming profitable ones by 2,000 basis points since Liberation Day, which signals casino-like investor behavior and elevated risk rather than a healthy market broadening.

AI hype resembles late-1990s internet bubble.
Generative AI and technology dominance have spread through the market into energy infrastructure, utilities, pipelines, and financials, but the total addressable market for AI remains uncertain and investors are paying up like in the late-1990s internet bubble, creating bubble-like risk.

Fed cuts and inflation downside favor Treasuries.
The Fed will eventually cut rates and inflation is likely to surprise to the downside through 2026 because tariff effects are peaking, shelter disinflation is coming through, and food and agriculture commodity inflation has fallen, which should support long-duration Treasuries even though long yields have not fallen much yet.
