Goldman Sachs: 10 Stocks Drive 68% of Q3 Earnings Growth — Don't Fight the Concentration
nashnova research
Goldman partner Mark Wilson says just 10 stocks drove 68% of Q3 earnings growth, pushing market concentration to an extreme; his core call — betting against that concentration is costly until the data actually shifts.
68% of earnings growth from just 10 stocks — what does that mean?
In the current Q3 earnings season, just 10 stocks account for 68% of total earnings growth — concentration is at an extreme.
At the sharpest end, two stocks alone drive a third of all earnings growth.
This means → most stocks contribute almost nothing to earnings growth. Market "breadth" is an illusion — very few companies are actually growing profits, and index performance hinges on a handful of giants.
How bad is investor sentiment right now?
After a two-week client roadshow, Wilson summarized: sentiment and positioning data are fully aligned, and what the positioning data shows is "about as bad as it gets."
His phrasing is blunt: momentum has flipped from tailwind to trap, and investors are "seeing ghosts around every corner."
This reflects a market that has entered a "good news is bad news" state — the problem isn't the headlines themselves, but the fact that holders' nerves are stretched to breaking point.
Positive headlines kept coming — so why did the market fall?
This week brought several positive signals: a strong 10-year Treasury auction and record results from two of the world's largest chipmakers.
None of it lifted the market. Instead, each headline became a reason for investors to take profits.
In plain terms = when sentiment is bad enough, good news stops being a "buy" signal and becomes an exit — "finally, a decent price to sell at." Wilson's diagnosis: the problem isn't the news, it's the people.
"Don't fight concentration" — what's the logic behind that call?
Wilson's core stance is right in the report title: "Don't fight concentration."
His logic: when a handful of stocks dominate earnings growth, strategies that bet on a return to market breadth — expecting gains to spread more evenly — face persistent headwinds.
This means → it's not that concentration carries no risk. It's that, until the data actually changes, trading against concentration costs more than living with it. Put simply = don't rush to bottom-fish stocks that "should be rising but aren't" — wait for the structure to genuinely loosen.
