As the underperformance of U.S. growth is mainly attributable to weakness in the Magnificent Seven names. The question becomes: Has the Mag 7 become the Lag 7?
Magnificent Seven Fundamentals
To answer that question, I begin by reviewing the fundamentals of the Magnificent Seven stocks, which mainly translates into the fundamentals and expectations of the AI boom.
The margin expansion story may be about to change. Analysis from FactSet shows that while earnings growth expectations of the Magnificent Seven lead the S&P 493, the expected growth differential between Q4 2025 and CY 2006 is narrowing.
If the underperformance of large-cap stocks is based on changes in expectations, a bull case can be made by observing that cap-weighted 2026 earnings revisions are outperforming equal-weighted earnings revisions.
Too Far, Too Fast
Arguably, the recent underperformance of U.S. large-cap growth is a case of a group of stocks that became overbought and staged a reversal. The accompanying chart shows the relative performance of the Russell 1000 Growth to Russell 1000 Value ratio. The ratio became overbought in early November, as measured by the 14-day RSI, and recently fell to an oversold reading. Similar episodes in the last five years have led to bounces, though it’s an open question as to whether a reversal is durable.
Indeed, the pullback in technology and growth stocks reached a phase that the forward P/E of the technology sector fell to second place behind the forward P/E of the consumer discretionary sector.
From a technical perspective, U.S. large-cap growth is washed out and ready to bounce. The NASDAQ 100, which is a proxy for large-cap growth, has staged a rally but pulled back from overhead resistance. Relative breadth indicators (bottom two panels) are showing signs of improvement.
The Value of Diversification
Putting it all together, how should investors react to the recent weakness and recovery in U.S. large-cap growth? Is the strength in the Magnificent Seven over?
My crystal ball is cloudy. Under such conditions, I continue to believe investors should maintain a diversified allocation to the barbell strategy of U.S. large-cap growth and EAFE value in their equity allocations.









Every year for the last few we have experienced higher PE valuations that boosted stock prices over earnings gains. Investors assume that stocks will go up with earnings as a minimum plus extra from the hopeful PE boost. But a rising PE is due to stocks forecasting better times ahead. I don’t see those better times in 2027 post the November Dem winning the House and the strong possibility of higher long-term interest rates.
If the PE on the S&P 500 went back to Jan 2020 pre-Covid the market would go down 17%. If it went down to 2022 low PE, it would go down 27%. That is with forward earnings estimates being realized. If earnings fall short, the drop would be larger.
The average drawdown in the second year of a two term President is 18%. PE compression in a good economy is the way to that happening.
Thank you Cam and Ken for your excellent analysis. I would like to point out that there could be a contribution of the monetary policy in the valuation. During Covid central banks printed enough money to buy another planet
