Yields Above 5% and the Nasdaq 100 Still Won't Crack
A ten-year Treasury yield above five percent is supposed to punish long-duration growth stocks. The Nasdaq-100 has not obliged, and the reason sits on six corporate balance sheets.
The ten-year Treasury yield has pushed above five percent without dragging the Nasdaq-100 lower, a resilience 24/7 Wall St attributes to the balance sheets of six mega-cap companies; the QQQ ETF tracking the index closed at $744.50, up 0.46%, on Sept. 25, 2026.
The textbook says this is not supposed to happen. When the ten-year Treasury yield climbs above five percent, the discount rate applied to every dollar of future corporate profit rises with it, and the stocks that promise the most distant earnings are supposed to fall hardest. Growth indexes are long-duration assets. Higher rates shorten the investor's patience.
And yet the Nasdaq-100 has refused to break. The Invesco QQQ Trust (NASDAQ: QQQ), the exchange-traded fund that tracks the index, closed at $744.50 on Friday, Sept. 25, 2026, up 0.46% from its prior close of $741.10, with an intraday range of $739.64 to $745.91. That is a quiet session, not a repricing. Over the same stretch the S&P 500 proxy SPY closed at $771.35, up 0.54%, and the Dow 30 proxy DIA closed at $517.49, up 0.94%.
Where the rate-transmission mechanism breaks down
The mechanism by which rates are supposed to hurt equities is not mystical. It works through three channels: the discount rate applied to future cash flows, the cost of refinancing existing debt, and the cost of funding new investment. A company that has to roll over borrowings into a five-percent-plus market pays more, earns less, and is worth less.
Each of those channels requires the company to actually need the bond market. 24/7 Wall St traces the index's stubbornness to the balance sheets of six companies — the cluster of mega-caps whose weight in the Nasdaq-100 is large enough that their behavior effectively is the index's behavior. When those firms carry net cash rather than net debt, fund capital expenditure from operating cash flow, and hold term debt issued years ago at far lower coupons, two of the three transmission channels simply do not connect.
That leaves the discount-rate channel, which is real but is a matter of investor arithmetic rather than corporate arithmetic. And a discount-rate effect can be offset by an upgrade to expected cash flows. If the market believes earnings power is rising faster than the required return, the valuation holds. That is the bet being made at current levels, whether or not investors would phrase it that way.
A cash-rich balance sheet is a rate hedge
There is a second-order effect that gets less attention than it deserves. For a company sitting on a large net cash position, a higher risk-free rate is not purely a cost — it is income. Interest earned on short-dated Treasury and money-market holdings rises with the same curve that is punishing leveraged borrowers. The five-percent world that squeezes a highly indebted industrial rewards a corporate treasury running a surplus.
That asymmetry is why the same yield move produces such different outcomes across the market. The index membership does the sorting. The Nasdaq-100 is, by construction, weighted toward companies that spent the past decade generating more cash than they could redeploy. The result is an index that behaves less like a long-duration bond proxy and more like a portfolio of self-funding cash machines with an equity option attached.
What the day's tape actually says
Look at the relative performance in the most recent session and the picture is subtler than "growth is immune." The Dow proxy's 0.94% gain outpaced the Nasdaq-100 proxy's 0.46% by roughly 0.48 percentage points on the day — a modest rotation toward cyclicals and away from long-duration tech, not a rout. The Nasdaq-100 proxy's intraday range spanned about 0.85% of its prior close. These are the numbers of an index absorbing a rate shock, not ignoring one.
That distinction matters. "Refuses to fall" is not the same as "rallies through it." What the tape shows is a growth index holding its ground while the rest of the market leads modestly. The absence of breakage is the story; outperformance is not being claimed.
Concentration cuts in both directions
" What the tape shows is a growth index holding its ground while the rest of the market leads modestly.
Here is the uncomfortable corollary. If six balance sheets are strong enough to hold a 100-stock index up against a five-percent ten-year, those same six are load-bearing on the way down. An index insulated from rates by concentration is an index exposed to anything that impairs the specific companies doing the insulating — a capital-spending cycle that stops converting into earnings, a regulatory action, a demand disappointment in one product line.
Investors who read the index's rate-resilience as a broad signal about growth equities are drawing the wrong conclusion. The resilience is not diffusing across the other names in the Nasdaq-100; it is being supplied by a handful of constituents whose weight overwhelms whatever the smaller members are doing. A screen of equal-weighted technology performance would very likely tell a different story than the cap-weighted headline.
What would actually break the pattern
Three developments would test the thesis. First, evidence that the cash-rich cohort is moving from net cash toward net debt — large acquisitions, aggressive buyback funding, or data-center capital programs financed in the bond market rather than from operating cash flow. That would reconnect the refinancing channel.
Second, a yield move driven by credit or fiscal stress rather than growth. A ten-year above five percent because the economy is running hot is survivable for equities; the same level reached because buyers are demanding a higher term premium for holding government paper is a different animal, because it lifts the discount rate without lifting expected cash flows.
Third, a change in the composition of the leadership. If the six names that have been carrying the index start to diverge from each other, the insulation thins fast.
How to read this as an investor
The practical takeaway is that the old heuristic — rates up, growth down — has stopped functioning as a reliable trading rule in this market, but not because the underlying finance changed. Discounted cash flow still works. What changed is the corporate finance of the companies at the top of the index. They stopped being borrowers.
That is a durable condition until it isn't, and it is observable. Anyone relying on it can check it directly in quarterly filings: net cash position, weighted-average coupon on outstanding debt, the maturity schedule, and the share of capital expenditure covered by operating cash flow. Those four lines explain more about how the Nasdaq-100 handles a five-percent ten-year than any macro forecast will.
For now, the index is doing what the balance sheets permit it to do. The yield is high, the discount rate is real, and the market has decided the cash flows are growing fast enough to cover it. That is a judgment, not a law — and judgments get revised.

Frequently asked questions
Why are higher Treasury yields supposed to hurt growth stocks?
Growth stocks derive most of their value from profits expected years in the future. Valuing those profits today requires discounting them at a rate tied to the risk-free Treasury yield. When the ten-year yield rises above five percent, the discount applied to distant cash flows grows larger, mechanically reducing the present value of long-duration equities more than that of companies earning cash now.
What level is the Nasdaq-100 trading at right now?
The Invesco QQQ Trust, the exchange-traded fund tracking the Nasdaq-100, closed at $744.50 on Friday, Sept. 25, 2026, a gain of 0.46% from the previous close of $741.10. Its intraday range that session ran from $739.64 to $745.91. Markets were closed at the time of the most recent quote, so that is the last traded price.
Which six companies are credited with holding the index up?
The reporting attributes the Nasdaq-100's resilience to six mega-cap companies whose balance sheets blunt the effect of higher rates, without those specific names being enumerated in the summary. What matters structurally is the profile: net cash positions, capital spending funded internally, and existing debt locked in at older, lower coupons.
How can a high interest rate actually help a company?
A company holding a large net cash position invests that cash in short-dated Treasury bills and money-market instruments. When yields rise above five percent, the interest income on those holdings rises too. So the same rate environment that increases borrowing costs for indebted firms increases investment income for cash-rich ones, creating an asymmetry across the market.
Does the Nasdaq-100's strength mean growth stocks generally are immune to rates?
No. The index is capitalization-weighted, so a small number of very large constituents can hold the headline level steady while smaller members underperform. Resilience supplied by a handful of balance sheets does not diffuse to the rest of the index. Equal-weighted measures of technology performance would likely show a different picture than the cap-weighted number.
What would signal that the pattern is breaking?
Three things to watch: the cash-rich cohort shifting toward net debt by financing acquisitions or data-center capital spending in the bond market; a yield rise driven by fiscal or credit stress rather than economic growth, which lifts discount rates without lifting expected earnings; and divergence among the handful of large constituents currently moving together.
