Why Rising Bond Yields Hit the Nasdaq Harder Than the Dow

The yield on the 10-year US Treasury has climbed to around 4.8%, a level not seen since early 2025, as an oil-driven inflation scare pushes the Federal Reserve toward a rate hike this month. Equity indices have wobbled — and, as usual, not evenly. The technology-heavy Nasdaq has been more sensitive than the industrial Dow. This is not a coincidence, and understanding why is the difference between trading indices and trading a random number.

Why do higher yields hurt tech stocks?

A share is worth the cash it will pay its owner in the future, discounted back to today. The discount rate is built on the government bond yield. When the 10-year yield rises, every future dollar is worth a little less today — and the further in the future the dollar is, the more it is worth less. A utility paying a steady dividend now is barely affected. A company whose value rests on profits five or ten years out is affected a great deal.

That is the mechanical reason the NAS100, dominated by growth companies whose earnings are weighted toward the future, tends to fall further than the US30 when yields rise. The Dow's thirty members are older, dividend-paying businesses whose value is closer to the present. The S&P 500 sits between them, and the small-cap US2000 — full of companies that borrow at floating rates — often does worst of all when financing costs climb.

There is a second, more human reason. When a safe bond pays close to 5%, the case for owning something risky has to be better than it was when the bond paid 1%. That gap is the equity risk premium, and when it compresses, money leaves equities for bonds without any change in the companies themselves.

Which index does what

Index	What drives it	Sensitivity to yields
NAS100	Large-cap technology and growth	Highest
S&P500	Broad US market	Moderate
DOW30	Industrials, financials, dividend payers	Lowest of the three
US2000	Small caps, floating-rate borrowers	High, via financing costs

A trader who is short NAS100 and long DOW30 is not hedged; they are expressing a view on yields. That can be a perfectly good trade — but it should be sized as one position, because on a yield shock it will behave like one. The contract sizes and margin requirements differ between the indices, and the margin calculator shows what each leg ties up.

Single stocks feel it too — unevenly

Among the individual US stock CFDs we list, the effect is sharpest in the names whose valuations rest most on future growth. NVDA and the other large AI-linked names have carried the market for two years on expectations that stretch a long way out; those are precisely the cash flows a higher discount rate hurts most. That does not mean they fall on every yield uptick — earnings can overwhelm rates for a while — but it does mean they move more per basis point than a bank or an industrial.

Can you trade bonds as CFDs?

Yes. A bond CFD tracks the price of a government or corporate bond, and bond prices move inversely to yields: when yields rise, the bond price falls. That inverse relationship is the whole reason bond CFDs are interesting to an index trader right now — being short a long-dated government bond is, in effect, being long yields, which is the same macro view that being short NAS100 expresses, in a different instrument with different characteristics. Our bond trading guide covers the mechanics: duration, why long-dated bonds move more than short-dated ones, and how the price–yield relationship works.

Two cautions. Bond CFDs are less liquid than the major indices and can gap on central bank news. And some bond instruments are offered without leverage, so the margin is the full notional — check the contract specifications for the exact terms of any bond you are considering before sizing a position.

Positioning into 16 September

If the Fed hikes and signals more, yields may push higher and the pattern above continues: NAS100 and US2000 under the most pressure, DOW30 the least. If the Fed hikes and signals it is done, the long end of the yield curve could actually rally on relief — bond prices up, growth stocks up — even as the policy rate rises. That second scenario catches out traders who assume "hike = stocks down" without thinking about which part of the curve equities actually care about.

The instrument to watch is the 10-year, not the Fed funds rate. The Fed sets the overnight rate; the market sets the 10-year, and it is the 10-year that discounts the Nasdaq's future.
