Why the Nasdaq Refuses to Break Even With Treasury Yields Above Five Percent

The ten-year Treasury yield just hit levels that should be crushing growth stocks, yet the Nasdaq-100 keeps refusing to fall. The reason comes down to six companies whose balance sheets are rewriting the rules of how rate pressure actually transmits.

The long end of the Treasury curve pushed to fresh highs, with the ten-year yield at 5.18% and the thirty-year at 5.47%, yet the Invesco QQQ Trust (NASDAQ:QQQ) closed the session at $741.10, down 0.01%.

The Dow slipped while the Nasdaq-100 held. Standard valuation theory says the index most exposed to long-duration cash flows should have taken the largest hit. Instead, a handful of megacap names carried the session, which is why QQQ refuses to crack and why it is thinner than the flat close implies.

Every Treasury maturity from five years to thirty was above 5.00% on 2026-09-24, with the twenty-year at 5.53%. The five-year sat at 5.03% and the seven-year at 5.10%.

QQQ carried a 3.37% one-week gain and a 20.64% year-to-date advance. The VIX at 14.21 on 2026-09-22 signals almost no hedging demand, unusual against a curve this high.

These firms generate more cash than they need to fund operations, so a higher cost of capital hurts competitors more than it hurts them. Balance-sheet quality explains why the index held while long rates rose.

When six names carry these weights, you own concentrated exposure to a handful of businesses rather than a diversified technology position. The two Alphabet (NASDAQ:GOOG, NASDAQ:GOOGL) share classes add another 3.27% and 3.02% on top of that.

These companies commit enormous amounts to AI capital spending, precisely the activity a higher cost of capital hurts (the power, cooling, and networking suppliers absorbing that spend are the subject of a free report we put together here: seven AI infrastructure names that aren’t chipmakers). Concentration is the engine on days like this and the fault line when one of these names disappoints.

Real yields, which strip out inflation, have kept climbing. The ten-year real yield reached 2.85% on 2026-09-24, up from 2.44%.

Higher real yields lift the discount rate applied to distant cash flows, which is what a growth index depends on. Mortgage rates, tied to the long end, transmit the same pressure into household budgets before it reaches earnings.

The Federal Funds target upper bound sits at 4% as of 2026-09-24, so this long-end move reflects the market repricing of the term premium and inflation risk without policy help, rather than Fed action.
