US mega-cap tech stocks single-handedly prop up indices as elevated rates weigh on most sectors
nashnova research
The S&P 500 gained 3.9% over three months, yet the equal-weight index fell 2.1% — more than 70% of constituents are down over 10% from their highs, and rates near 5.3% are splitting the market in two.
The index is rising — so why are most stocks falling?
The S&P 500 climbed 3.9% in three months, driven almost entirely by the "Magnificent Seven" mega-cap tech names. The Invesco equal-weight ETF (RSP) — which treats all 500 stocks the same — fell 2.1% over the same period.
This means → unless you are heavily concentrated in a handful of giant tech stocks, your actual return is most likely negative.
Morgan Stanley's Lisa Shalett noted the index sits just ~1% below its all-time high, yet over 70% of its constituents have pulled back more than 10% from their individual peaks.
In plain terms = the index is a weighted average; a few trillion-dollar companies are heavy enough to drag it upward even while the majority of stocks decline.
What does a 5.3% Treasury yield do to stocks?
The 10-year Treasury yield hovers near 5.3%, pressing down on rate-sensitive sectors: consumer staples, consumer discretionary, utilities, and healthcare.
This means → when a risk-free government bond pays 5.3%, investors demand even higher returns from stocks — especially slower-growth, dividend-reliant sectors — making those shares harder to bid up.
Shalett warned that sustained high rates could push more companies into "earnings-downgrade territory."
Where do two strategists see the market heading?
Stifel strategist Thomas Carroll set a year-end S&P 500 target of 7,900 — roughly 2% above current levels — and framed the market as "a tale of two economies": red-hot industrial capex versus inflation-squeezed consumers.
Shalett is more optimistic: her mid-2027 target is 8,300, about 7% higher.
Yet she conceded the index's ability to hold depends heavily on continued mega-cap tech support — this reflects a deep market reliance on the AI narrative staying intact.
What should investors buy in a high-rate world?
Carroll argued that Fed Chair Kevin Warsh's persistent focus on inflation will keep long-end rates elevated. In that backdrop he flagged two lanes: AI-beneficiary chip stocks and capex-driven cyclicals.
Chips: Nvidia, Micron; equipment makers KLA, Lam Research, Teradyne, Applied Materials.
Cyclicals: oil & gas producers APA, Diversified Energy; transport names Old Dominion Freight Line, C.H. Robinson; industrials Comfort Systems, Sterling Infrastructure, Valmont.
Where is the biggest risk hiding?
The core tension: index-level calm masks severe internal divergence.
Whether this split can persist hinges on whether the AI theme keeps supplying valuation support to mega-cap tech.
In plain terms = the entire index is like a table standing on just a few legs. If the AI story falters and those legs wobble, the crushing weight of high rates on everything else will be fully exposed.
